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 <code>$mail-&gt;Password = &quot; por$ch3&quot;;</code> is valid but will not work using the code above .
The solution should be as follows: <code>$mail-&gt;Password = &quot;por\$ch3&quot;;</code>
Note the Backslash I placed before the dollar character within my password.
That should work if you have a password using special characters

I experienced the same error when configuring the <code>WP-Mail-SMTP</code> 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.

<ol>
<li>Create a new password for the Gmail account you want to use</li>
<li>Enable less secure apps in <a href="https://myaccount.google.com/lesssecureapps" rel="nofollow noreferrer">Google Security settings</a></li>
<li>Use the <a href="http://www.google.com/accounts/DisplayUnlockCaptcha" rel="nofollow noreferrer"><code>Display Unlock Captcha</code> page</a> to give your app or website permission to sign in to Gmail. Click <code>Continue</code> or follow the instructions.</li>
<li>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</li>

SMTP Error: could not authenticate
I had the same problem. The following troubleshooting steps helped me.

<ul>
<li>I turned off two-factor authentication in my gmail account.</li>
<li>I allowed less secure apps to access my gmail account. To get it working, I had to go to <code>myaccount.google.com</code> -> <code>Sign-in &amp; security</code> -> <code>Apps with account access</code>, and turn <code>Allow less secure apps</code> to <code>ON</code> (near the bottom of the page).</li>
<li>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.</li>
<li>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.</li>
<li>Try registration again. It should now work.</li>
</ul>

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: 

<pre><code>a. Go to the URL of `https://myaccount.google.com/` and click `Sing-in and security`

b. Click on the app password. 
</code></pre>

<a href="https://i.stack.imgur.com/0iUHt.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/0iUHt.png" alt="enter image description here"></a> 

<pre><code>You will reach a page like this,

<a href="https://i.stack.imgur.com/3y4oZ.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/3y4oZ.png" alt="enter image description here"></a>

<pre><code>c. Create name of your app and generate a password for the respective app. 

d. Use that password acquired here inside the app.
</code></pre>

This should resolve the issue.

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)

my solution is:

<li>change gmail password</li>
<li>on gmail &quot;Manage your google Account&quot; &gt; Security &gt; Turn on 3rd party app Access</li>
<li>This the new step that i discover by UnlockingCaptcha that told in this <a href="https://support.google.com/mail/thread/27318463?hl=en" rel="nofollow noreferrer">site</a>, the exact site is <a href="https://accounts.google.com/b/0/DisplayUnlockCaptcha" rel="nofollow noreferrer">https://accounts.google.com/b/0/DisplayUnlockCaptcha</a>, but maybe you want to read the former site first.</li>
</ol>
That all, hope it works for you

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!):

<blockquote>

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:

<pre><code> &lt;?php
 require_once ("PHPMailer\class.phpmailer.php");
 $Correo = new PHPMailer();
 $Correo-&gt;IsSMTP();
 $Correo-&gt;SMTPAuth = true;
 $Correo-&gt;SMTPSecure = "tls";
 $Correo-&gt;Host = "smtp.gmail.com";
 $Correo-&gt;Port = 587;
 $Correo-&gt;UserName = "foo@gmail.com";
 $Correo-&gt;Password = "gmailpassword";
 $Correo-&gt;SetFrom('foo@gmail.com','De Yo');
 $Correo-&gt;FromName = "From";
 $Correo-&gt;AddAddress("bar@hotmail.com");
 $Correo-&gt;Subject = "Prueba con PHPMailer";
 $Correo-&gt;Body = "&lt;H3&gt;Bienvenido! Esto Funciona!&lt;/H3&gt;";
 $Correo-&gt;IsHTML (true);
 if (!$Correo-&gt;Send())
 {
 echo "Error: $Correo-&gt;ErrorInfo";
 }
 else
 {
 echo "Message Sent!";
 }
?&gt;
</code></pre>

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.
