I'm using PHPMailer in a Simple Script For Send Email's Through Gmail, and I'm getting an "Unknown Error" (At least for me!):
SMTP Error: Could not authenticate.
Error: SMTP Error: Could not
authenticate.

I've read about Configure OpenSSL For SSL/TLS Connections, and I did it. Apache And PHP Are properly-Configured (With OpenSSL extension Running in PHP and mod_ssl running in Apache 2.2.16).
This is The PHP Script:
<?php
require_once ("PHPMailer\class.phpmailer.php");
$Correo = new PHPMailer();
$Correo->IsSMTP();
$Correo->SMTPAuth = true;
$Correo->SMTPSecure = "tls";
$Correo->Host = "smtp.gmail.com";
$Correo->Port = 587;
$Correo->UserName = "foo#gmail.com";
$Correo->Password = "gmailpassword";
$Correo->SetFrom('foo#gmail.com','De Yo');
$Correo->FromName = "From";
$Correo->AddAddress("bar#hotmail.com");
$Correo->Subject = "Prueba con PHPMailer";
$Correo->Body = "<H3>Bienvenido! Esto Funciona!</H3>";
$Correo->IsHTML (true);
if (!$Correo->Send())
{
echo "Error: $Correo->ErrorInfo";
}
else
{
echo "Message Sent!";
}
?>
The Username and Password are OK, And I tried in Thunderbird, without any problem.
I've also Used SSL Authentication and Port 465, getting the same Error.
I encountered this problem. To get it working, I had to go to myaccount.google.com -> "Sign-in & security" -> "Apps with account access", and turn "Allow less secure apps" to "ON" (near the bottom of the page).
Alternatively you can follow this direct link to these settings
this is GMail issue
read this Google Help (https://support.google.com/mail/answer/14257?p=client_login&rd=1)
Open your web browser and sign in to Gmail at http://mail.google.com/mail. If you see a word verification request, type the letters in the distorted picture and finish signing in.
Close your browser and try accessing your messages in your email client again.
If you're still having problems, visit http://www.google.com/accounts/DisplayUnlockCaptcha and sign in with your Gmail username and password. If necessary, enter the letters in the distorted picture.
Click Continue.
Restart your mail client and try accessing messages in your email client again.
Try this instead :
$Correo->Username = "foo#gmail.com";
I tested it and its working perfectly without no other change
I received the same error and in mycase it was the password. My password has special characters.
If you supply the password without escaping the special characters the error will persist.
E.g $mail->Password = " por$ch3"; is valid but will not work using the code above .
The solution should be as follows: $mail->Password = "por\$ch3";
Note the Backslash I placed before the dollar character within my password.
That should work if you have a password using special characters
Because Allow less secure apps is no longer available
The solution was to enable 2-step verification and generate app password
select mail and computer from the list then click generate
copy the code shown in the box and replace your google password with your app password it works like a charm.
I experienced the same error when configuring the WP-Mail-SMTP plugin in Wordpress.
The problem would persist even when I have 'triple checked' the settings and login credentials, and am able to log in manually using a browser.
There's a list of steps you can take to fix this.
Create a new password for the Gmail account you want to use
Enable less secure apps in Google Security settings
Use the Display Unlock Captcha page to give your app or website permission to sign in to Gmail. Click Continue or follow the instructions.
Sign in using the app or website. The smtp settings that work for me are 1) SMTP Host: smtp.gmail.com 2) SMTP port: 587 3) Encryption: TLS 4) Authentication: SMTP authentication 5) Username: example#gmail.com 6) Password: examplesecret
my solution is:
change gmail password
on gmail "Manage your google Account" > Security > Turn on 3rd party app Access
This the new step that i discover by UnlockingCaptcha that told in this site, the exact site is https://accounts.google.com/b/0/DisplayUnlockCaptcha, but maybe you want to read the former site first.
That all, hope it works for you
I received this error because of percentage signs in the password.
For me I had a special characters in my password field, and I put it like $mail->Password = " por$ch3" which work for gmail smpt server but not for other; so I just changed double quotes to single quotes and it works for me. $mail->Password = ' por$ch3';
If you still face error in sending email, with the same error message. Try this:
$mail->SMTPSecure = 'tls';
$mail->Host = 'smtp.gmail.com';
just Before the line:
$send = $mail->Send();
or in other sense, before calling the Send() Function.
Tested and Working.
The other post is correct to resolve the issue but doesn't address how to do it if the 2-step-verification is turned on. The option to allow the less secure apps is NOT available then. Here is an answer to how to do it:
a. Go to the URL of `https://myaccount.google.com/` and click `Sing-in and security`
b. Click on the app password.
You will reach a page like this,
c. Create name of your app and generate a password for the respective app.
d. Use that password acquired here inside the app.
This should resolve the issue.
I had the same issue and did all the tips including Gmail setting (e.g. less secure apps access) with no luck. But finally when I changed password to something different, for some reason it worked! FYI, the initial password did not have any special characters.
first go to https://myaccount.google.com
Select Security tab
Scroll down and select 'Less secure app access'
Turn on access
This will solve my “SMTP Error: Could not authenticate” in PHPMailer error.
I had the same issue and did all the tips with no luck. Finally when I changed password to something different, for some reason it worked! (the initial password or the new one did not have any special characters)
The correct answer:
Go to "Manage your google accounts => Security => Signing in to Google => App passwords".
Generate your maill account password there (that will be used from other device)
I had the same problem with authentication. The fix was to set up 2-step verification and create an application specific password for the device ( error messages for blocking the device will appear in your account settings->"Notifications and alerts" if you problem is the same with mine)
It was the selinux issue. I just updated the below given part in /etc/selinux/config file
SELINUX=permissive (it was SELINUX=enforcing before).
then just reboot the system by giving
reboot
Now the mail goes without any hassle.
Configuration
From Email Address : [noreply#yourdomain.com]
From Name : [your domain name]
SMTP Host : smtp.gmail.com
Type of Encryption : SSL
SMTP Port : 465
SMTP Authentication : YES
Username : [your mail id]
Password : [your password]
SMTP Error: could not authenticate
I had the same problem. The following troubleshooting steps helped me.
I turned off two-factor authentication in my gmail account.
I allowed less secure apps to access my gmail account. To get it working, I had to go to myaccount.google.com -> Sign-in & security -> Apps with account access, and turn Allow less secure apps to ON (near the bottom of the page).
At this step, when I tried to register a user, I would get the same error. Google would sent me a warning message that someone has my password and the login was blocked.
Gmail will then provide you with options. You either click whether the activity was yours or not yours. Click the option that the activity was yours.
Try registration again. It should now work.
There is no issue with your code.
Follow below two simple steps to send emails from phpmailer.
You have to disable 2-step verification setting for google account if you have enabled.
Turn ON allow access to less secure app.
I had the same issue which was fixed following the instructions below
Test enabling “Access for less secure apps” (which just means the client/app doesn’t use OAuth 2.0 - https://oauth.net/2/) for the account you are trying to access. It's found in the account settings on the Security tab, Account permissions (not available to accounts with 2-step verification enabled): https://support.google.com/accounts/answer/6010255?hl=en

SOLVED
In 2022 the reason i found that
You need to do two-factor authentication in your mail service.
I am using Mail.ru https://account.mail.ru/user/2-step-auth/passwords/
Source:
https://www.courier.com/error-solutions/smtp-error-could-not-authenticate/
I am using PHPMailer to send emails in PHP using SMTP with username & password authorization.
It works well, but I am concerned about hard coding the SMTP username & password in the php file.
Other threads on Stack Overflow have suggested "storing the username & password in an 'ini' file outside of the web server / document root"
So I've stored it in inetpub, but before wwwwroot. Eg. E:\inetpub\smtp.ini
Where as my websites are stored in E:\inetpub\wwwroot\exampleWebsite
My question is: Is my smtp.ini file stored in a 'non-public' area? In other words, if a website user can access wwwroot, can they also access a file in inetpub? Or is there a better folder / sub folder I should be storing it in?
My PHP code is as follows:
$path = realpath('/inetpub/smtp.ini');
$config = parse_ini_file($path, true);
$mail = new PHPMailer(true);
$mail->isSMTP();
$mail->Host = 'outlook.office365.com';
$mail->SMTPAuth = true;
$mail->Username = $config['smtp']['un'];
$mail->Password = $config['smtp']['pw'];
// ... rest of mail function ...
$mail->send();
What you're doing is safe: the file is outside the web root and so has no external URL (assuming your server doesn't allow silly things like letting relative URLs go out of the web root like ../../smtp.ini). You could protect it further by making it render to nothing, for example by adding a line like this at the start and then saving it as a .php file:
;<?php return false;
This looks like a harmless comment to an ini-file parser, but will produce a blank page if accessed as a PHP file.
I am trying to setup a php page to automatically send a verification email. I would like to use the gmail smtp servers, and everywhere I've looked suggests to use PHPMailer. I installed it and used the following example code:
ini_set('display_errors', 1);
error_reporting(E_ALL);
require_once ("incl\PHPMailer\PHPMailerAutoload.php");
$mail = new PHPMailer();
$mail->IsSMTP();
$mail->SMTPAuth = true;
$mail->SMTPSecure = "tls";
$mail->Host = "smtp.gmail.com";
$mail->Port = 587;
$mail->Username = "myemail#gmail.com";
$mail->Password = "mypassword";
$mail->SetFrom('myemail#gmail.com','Me');
$mail->AddAddress("ToAddress#gmail.com");
$mail->Subject = "Verify your email";
$mail->Body = "Thank you for signing up. Please verify your email using the link below:";
$mail->IsHTML (true);
if($mail->Send()){
echo "Success";
}else{
echo "Error";
}
When trying to access the page via Firefox, the page will load for a few minutes, then give this error:
500 - Internal server error.
There is a problem with the resource you are looking for, and it cannot be displayed.
The server is Windows Server 2008 R2 Standard running IIS 7.5 and PHP Version 5.5.8. I can access all other pages without issues, but trying to call $mail->Send() seems to be timing out or something. I know this because I commented every line and slowly added pieces back in and $mail->Send() is the line that causes the behavior.
My Google abilities are failing me here as I simply cannot figure out how to make this work. Any ideas on what might be wrong?
Update
I opened the server log then tried loading the page again, but no new errors were added to the log. However, I noticed the following errors from today in System32\LogFiles\httperr1.log
2014-10-27 06:29:21 1.161.23.122 3148 212.83.145.123 80 HTTP/1.0 CONNECT mx2.mail2000.com.tw:25 400 - URL -

UPDATE 2
I am positive that my gmail account details are correct and have tested sending from it using Thunderbird on the server. When trying to sent without secured methods, as suggested in this comment I get this error:
MAIL FROM command failed,550,5.7.3 Requested action aborted; user not authenticated
My PHP Mailer version is 5.2.9 and I've now also tried the following:
Using \\ in file paths instead of \
No change
Including class.phpmailer.php instead of PHPMailerAutoload.php
Fatal error: Class 'SMTP' not found in C:\inetpub\wwwroot\incl\PHPMailer\class.phpmailer.php on line 1195
Using ssl over port 465
SMTP connect() failed
Sending with a hotmail address over port 25 with $mail->SMTPAuth = false;
MAIL FROM command failed,550,5.7.3 Requested action aborted; user not authenticated
Update 3
After reloading the problem page, I checked through the Event Viewer and saw a new entry in Windows Logs -> System:
PHP Error : syntax error, unexpected BOOL_TRUE in C:\PHP\php.ini on line 101
That line is:
php_flag display_errors on
Looks like you're dealing with bunch of issues and here is a checklist: you're having issues with ssl, the actual mail software and credentials. It became an issue of 3 from one main issue and I'm guessing you don't either have your credentials typed in correctly or your open ssl isn't setup and you're also having issues using the mail software.
535 535 5.7.3 Authentication Unsuccessful means auth is unsuccessful, check your credentials username and password.
550 error code, it means that the receiving system could not deliver your email to the user to whom it was addressed because the mailbox is unavailable.
There are plenty of other solutions to resolve your issue. Why don't you try something more simple instead of using the autoload PHPMailerAutoload.php. Create a new file and place the code below, create a message body (test_message.html) and call it from the browser to test gmail smtp with the gmail credentials. This is a snippet from PHPMailer on how to use it with gmail smtp and it shouldn't go wrong if you have everything filled in correctly.
<?php
require_once('../class.phpmailer.php');
//include("class.smtp.php"); // optional, gets called from within class.phpmailer.php if not already loaded
$mail = new PHPMailer();
$body = file_get_contents('test_message.html');
$body = eregi_replace("[\]",'',$body);
$mail->IsSMTP(); // telling the class to use SMTP
$mail->Host = "mail.yourdomain.com"; // SMTP server
$mail->SMTPDebug = 2; // enables SMTP debug information (for testing)
// 1 = errors and messages
// 2 = messages only
$mail->SMTPAuth = true; // enable SMTP authentication
$mail->SMTPSecure = "tls"; // sets the prefix to the servier
$mail->Host = "smtp.gmail.com"; // sets GMAIL as the SMTP server
$mail->Port = 587; // set the SMTP port for the GMAIL server
$mail->Username = "yourusername#gmail.com"; // GMAIL username
$mail->Password = "yourpassword"; // GMAIL password
$mail->SetFrom('name#yourdomain.com', 'First Last');
$mail->AddReplyTo("name#yourdomain.com","First Last");
$mail->Subject = "PHPMailer Test Subject via smtp (Gmail), basic";
$mail->AltBody = "To view the message, please use an HTML compatible email viewer!"; // optional, comment out and test
$mail->MsgHTML($body);
$address = "whoto#otherdomain.com";
$mail->AddAddress($address, "John Doe");
$mail->AddAttachment("images/phpmailer.gif"); // attachment
$mail->AddAttachment("images/phpmailer_mini.gif"); // attachment
if(!$mail->Send()) {
echo "Mailer Error: " . $mail->ErrorInfo;
} else {
echo "Message sent!";
}
?>
If you're getting user auth error, then your credentials aren't typed in
correctly. If that's not the issue, you'll get an ssl error if you're not using the right port.
If there are software issues with include, you should try something better.
I was debating this morning if I should should PHPMailer, ended up using Swiftmailer which worked right after I installed it with PHPComposer.
My Internal mail server is extremely picky and has ton of firewall settings and rules on hardware and software level and I was surprised it didn't give me any problems; the emails were being sent right away without any problems on port 587.
require_once 'vendor/swiftmailer/swiftmailer/lib/swift_required.php';
$transport = Swift_SmtpTransport::newInstance('mail.hellog***.com', 587)
->setUsername('apache#hellog***.com')
->setPassword('apa******')
;
This is what you need for gmail:
$transporter = Swift_SmtpTransport::newInstance('smtp.gmail.com', 465, 'ssl')
->setUsername($this->username)
->setPassword($this->password);
$this->mailer = Swift_Mailer::newInstance($transporter);
If none of what you like, you can try phpgmailer:
https://github.com/GregDracoulis/LectureBank/tree/master/phpgmailer
here is an example on how to use it:
http://www.vulgarisoverip.com/2006/10/13/update-send-email-with-php-and-gmail-hosted-for-your-domain/
this class is dedicated for gmail use.
If all your problems and issues relate to openSSL, you should follow the steps below:
1. Make sure the OpenSSL module DLL file is included in the PHP installation:
C:\user>dir \local\php\ext\php_openssl.dll
Directory of C:\local\php\ext
php_openssl.dll
2. Create the PHP configuration file, \local\php\php.ini, if it does not exist:
C:\user>copy \local\php\php.ini-production \local\php\php.ini
1 file(s) copied.
3. Enable the OpenSSL module by editing the configuration file with a text editor. You need to remove the comment maker (;) on two configuration lines:
...
; Directory in which the loadable extensions (modules) reside.
; http://php.net/extension-dir
; extension_dir = "./"
; On windows:
extension_dir = "ext"
...
extension=php_openssl.dll
...
That’s it. You should be all set setting up openSSL on your Windows IIS WebServer. Follow these options and steps, it could be your issue.
This problem is slashes ( \ )
Edit
require_once ("incl\\PHPMailer\\PHPMailerAutoload.php");
I have tried with you code, and i have only changed this line :
require_once ("incl\PHPMailer\PHPMailerAutoload.php");
by this one :
require_once ("incl\PHPMailer\class.phpmailer.php");
And it was worked successfully.
Also you should keep attention about your PHPMailer version and your PHP version.
Have you tried to send an email with not secured method ?
Are you sure that your google credentials are valid ?
UPDATED
From the command line of your server, what is the output of this command and how much time that it takes to respond
telnet smtp.gmail.com 587
I wonder if you are running into the same issue that this question ran into. Google actively frowns on people using Gmail as their own personal SMTP server.
http://www.labnol.org/internet/email/gmail-daily-limit-sending-bulk-email/2191/
Google also limits the number of email messages that you can send through your Gmail account in a day. If you exceed the daily quota, Google may temporarily disable your Gmail account without any warnings and you may have to wait for up to 24 hours before you can regain access to your Gmail mailbox.
I could see an error like that potentially producing a 500 error.
From the comments to the question, it seems pretty clear that this issue is OpenSSL related.
You mentioned that you already have extension=php_openssl.dll uncommented, but phpinfo() does show it not beeing loaded.
Some thoughts:
Have you restarted the webserver, after uncommenting the openssl php module in your php.ini?
This is the really obvious one, but still worth mentioning. The php.ini is loaded on start-up, and not doing a service restart is simply a common mistake.
Check the value of Loaded Configuration File in phpinfo()
If this is not the same location than the php.ini which you have edited, it also becomes clear why it has not been loaded. Also following lines from phpinfo() might be worth checking.
Configuration File (php.ini) Path
Loaded Configuration File
Scan this dir for additional .ini files
There are other things too which can be done like uninstalling and reinstalling OpenSSL, but it might be good to check these more obvious things first.
Further thoughts:
Checking the error logs
For php the path can (again) be found in your phpinfo(). Look for the value of error_log and check the latest entries, right after you tried to reload your page.
Also you may wanna check the log files of IIS. If you don't know the path look in the IIS Manager, select the computer on the left pane, and in the middle pane, go under "logging" in the IIS area. Usually these will point to something like C:\inetpub\logs\LogFiles or C:\Windows\System32\LogFiles with a subfolder like W3SVC[x] where [x] is the website ID. (Will be just 1 if you only have one page, otherwise check the top level websites folder in IIS Manager, view the lists of sites in the right hand pane, it's the App ID)
Setting Up and Configuring IIS
Start by going to the ServerManager on you Server. Most often this is the server you’ll be running your php website on. Go to Add features in the Features summary section. Check SMTP Services in the Add Features Wizard and hit install. Now wait for the installation to finish. Open IIS6 (or IIS7) Manager under Administrative Tools -> Internet Information Services 6.0 in the Start Menu, the configuration of SMTP makes use of the management console from IIS6. Under [SMTP Virtual Server], click your right mouse button and select properties from the context menu. Go to the Access Tab and hit the Relay button.Add a new entry to the list by clicking the Add button and enter 127.0.0.1 (or your web server's IP) in the single computer entry field. Hit Ok two times to apply the new settings.
Configuring Php
To make Php send emails you need to make some configurations. Basically there are two options.
In case you’re only going to use the SMTP server in a single project and do not want it to interfere with other projects, you can set the configuration from within your php code by adding the following lines anywhere before sending the email:
ini_set('SMTP','localhost' );
ini_set('sendmail_from', 'administrator#YourWebsite.com');
Another way, to make global use of these settings, add the next lines to your php.ini file.
[mail function]
SMTP = localhost
sendmail_from = me#example.com
Make sure you restart your server after making these changes, to be sure they’re loaded.
This solution is provided here http://geekswithblogs.net/tkokke/archive/2009/05/31/sending-email-from-php-on-windows-using-iis.aspx on how to set up IIS and php and was provided as answer to this question 500 error when trying to use the MAIL function

I'm using a form on my website to send an email using the PEAR mail function. The email will send via gmail as described here - http://www.phpmaniac.net/wiki/index.php/Pear_Mail
I will therefore need to include something like the:
<?php
$smtp_params["host"] = "smtp.gmail.com";
$smtp_params["port"] = "25";
$smtp_params["auth"] = true;
$smtp_params["username"] = "user#gmail.com";
$smtp_params["password"] = "pass";
?>
Is it secure to put my username and password in the script like that? Obviously you wouldn't be able to see server-side script like this using 'View Source', but could you grab the source files via a web clipper or something and read the script that way? Thanks
If someone accidently disbles php parsing on you apache, your file will be served as plain text, so i like to keep passwords in config files outside my docroot... Just in case. Several times when building a new php modual for apche i forgot to copy a php.conf file into my httpd/conf.d/ direcoty and started apache without php. i
In theory, any insecure connection can be snooped. However, in this case it would need to be intercepted between your server and gmails smtp server. Also, even if you securly sent the email to the mail server, you have no certainty that they will connect securely to deliver it or the inteded receipient will securely check their email account.
In this case you just care about your basic auth being snooped. Use gmails secure ssl connection
Be safe by assuming all email communication is not secure. (unless you encrypt the message)
You should certainly use SSL/TLS for the connection - simply because sending passwords in plaintext over an unencrypted channel is a bad idea.
The login data inside your PHP script is safe as long as the PHP interpreter works properly and there are no security holes in your PHP scripts that allow an attacker to view the sourcecode of your PHP files.
Against the risk of misconfiguration causing PHP sourcecode to be visible an easy improvement would be storing the config file outside the document root.

I've read about Configure OpenSSL For SSL/TLS Connections, and I did it. Apache And PHP Are properly-Configured (With OpenSSL extension Running in PHP and mod_ssl running in Apache 2.2.16).
This is The PHP Script:
<?php
require_once ("PHPMailer\class.phpmailer.php");
$Correo = new PHPMailer();
$Correo->IsSMTP();
$Correo->SMTPAuth = true;
$Correo->SMTPSecure = "tls";
$Correo->Host = "smtp.gmail.com";
$Correo->Port = 587;
$Correo->UserName = "foo#gmail.com";
$Correo->Password = "gmailpassword";
$Correo->SetFrom('foo#gmail.com','De Yo');
$Correo->FromName = "From";
$Correo->AddAddress("bar#hotmail.com");
$Correo->Subject = "Prueba con PHPMailer";
$Correo->Body = "<H3>Bienvenido! Esto Funciona!</H3>";
$Correo->IsHTML (true);
if (!$Correo->Send())
{
echo "Error: $Correo->ErrorInfo";
}
else
{
echo "Message Sent!";
}
?>
The Username and Password are OK, And I tried in Thunderbird, without any problem.
I've also Used SSL Authentication and Port 465, getting the same Error.
I encountered this problem. To get it working, I had to go to myaccount.google.com -> "Sign-in & security" -> "Apps with account access", and turn "Allow less secure apps" to "ON" (near the bottom of the page).
Alternatively you can follow this direct link to these settings
this is GMail issue
read this Google Help (https://support.google.com/mail/answer/14257?p=client_login&rd=1)
Open your web browser and sign in to Gmail at http://mail.google.com/mail. If you see a word verification request, type the letters in the distorted picture and finish signing in.
Close your browser and try accessing your messages in your email client again.
If you're still having problems, visit http://www.google.com/accounts/DisplayUnlockCaptcha and sign in with your Gmail username and password. If necessary, enter the letters in the distorted picture.
Click Continue.
Restart your mail client and try accessing messages in your email client again.
Try this instead :
$Correo->Username = "foo#gmail.com";
I tested it and its working perfectly without no other change
I received the same error and in mycase it was the password. My password has special characters.
If you supply the password without escaping the special characters the error will persist.
E.g $mail->Password = " por$ch3"; is valid but will not work using the code above .
The solution should be as follows: $mail->Password = "por\$ch3";
Note the Backslash I placed before the dollar character within my password.
That should work if you have a password using special characters
Because Allow less secure apps is no longer available
The solution was to enable 2-step verification and generate app password
select mail and computer from the list then click generate
copy the code shown in the box and replace your google password with your app password it works like a charm.
I experienced the same error when configuring the WP-Mail-SMTP plugin in Wordpress.
The problem would persist even when I have 'triple checked' the settings and login credentials, and am able to log in manually using a browser.
There's a list of steps you can take to fix this.
Create a new password for the Gmail account you want to use
Enable less secure apps in Google Security settings
Use the Display Unlock Captcha page to give your app or website permission to sign in to Gmail. Click Continue or follow the instructions.
Sign in using the app or website. The smtp settings that work for me are 1) SMTP Host: smtp.gmail.com 2) SMTP port: 587 3) Encryption: TLS 4) Authentication: SMTP authentication 5) Username: example#gmail.com 6) Password: examplesecret
my solution is:
change gmail password
on gmail "Manage your google Account" > Security > Turn on 3rd party app Access
This the new step that i discover by UnlockingCaptcha that told in this site, the exact site is https://accounts.google.com/b/0/DisplayUnlockCaptcha, but maybe you want to read the former site first.
That all, hope it works for you
I received this error because of percentage signs in the password.
For me I had a special characters in my password field, and I put it like $mail->Password = " por$ch3" which work for gmail smpt server but not for other; so I just changed double quotes to single quotes and it works for me. $mail->Password = ' por$ch3';
If you still face error in sending email, with the same error message. Try this:
$mail->SMTPSecure = 'tls';
$mail->Host = 'smtp.gmail.com';
just Before the line:
$send = $mail->Send();
or in other sense, before calling the Send() Function.
Tested and Working.
The other post is correct to resolve the issue but doesn't address how to do it if the 2-step-verification is turned on. The option to allow the less secure apps is NOT available then. Here is an answer to how to do it:
a. Go to the URL of `https://myaccount.google.com/` and click `Sing-in and security`
b. Click on the app password.
You will reach a page like this,
c. Create name of your app and generate a password for the respective app.
d. Use that password acquired here inside the app.
This should resolve the issue.
I had the same issue and did all the tips including Gmail setting (e.g. less secure apps access) with no luck. But finally when I changed password to something different, for some reason it worked! FYI, the initial password did not have any special characters.
first go to https://myaccount.google.com
Select Security tab
Scroll down and select 'Less secure app access'
Turn on access
This will solve my “SMTP Error: Could not authenticate” in PHPMailer error.
I had the same issue and did all the tips with no luck. Finally when I changed password to something different, for some reason it worked! (the initial password or the new one did not have any special characters)
The correct answer:
Go to "Manage your google accounts => Security => Signing in to Google => App passwords".
Generate your maill account password there (that will be used from other device)
I had the same problem with authentication. The fix was to set up 2-step verification and create an application specific password for the device ( error messages for blocking the device will appear in your account settings->"Notifications and alerts" if you problem is the same with mine)
It was the selinux issue. I just updated the below given part in /etc/selinux/config file
SELINUX=permissive (it was SELINUX=enforcing before).
then just reboot the system by giving
reboot
Now the mail goes without any hassle.
Configuration

Password : [your password]
SMTP Error: could not authenticate
I had the same problem. The following troubleshooting steps helped me.
I turned off two-factor authentication in my gmail account.
I allowed less secure apps to access my gmail account. To get it working, I had to go to myaccount.google.com -> Sign-in & security -> Apps with account access, and turn Allow less secure apps to ON (near the bottom of the page).
At this step, when I tried to register a user, I would get the same error. Google would sent me a warning message that someone has my password and the login was blocked.
Gmail will then provide you with options. You either click whether the activity was yours or not yours. Click the option that the activity was yours.
Try registration again. It should now work.
There is no issue with your code.
Follow below two simple steps to send emails from phpmailer.
You have to disable 2-step verification setting for google account if you have enabled.
Turn ON allow access to less secure app.
I had the same issue which was fixed following the instructions below
Test enabling “Access for less secure apps” (which just means the client/app doesn’t use OAuth 2.0 - https://oauth.net/2/) for the account you are trying to access. It's found in the account settings on the Security tab, Account permissions (not available to accounts with 2-step verification enabled): https://support.google.com/accounts/answer/6010255?hl=en
