Failed to authenticate on SMTP server error using gmail

I'm trying to set up email for my first laravel project, and was thrilled that there's a laracast for it: https://laracasts.com/lessons/mailers

I've followed the simple steps, chose gmail in mail.php (x's added for anonymity): 

'driver' => env('MAIL_DRIVER', 'smtp'),
'host' => env('MAIL_HOST', 'smtp.gmail.com'),
'port' => env('MAIL_PORT', 587),
'from' => ['address' => '[email protected]', 'name' => 'Diane Kaplan'],
'encryption' => env('MAIL_ENCRYPTION', 'tls'),
'username' => '[email protected]',
'password' => 'xxxxx',
'sendmail' => '/usr/sbin/sendmail -bs',
'pretend' => false,

.env has (x's added for anonymity)- the laracast doesn't have us use MAIL_USERNAME and MAIL_PASSWORD, but they're updated for good measure assuming I'll pull from there later: 

MAIL_DRIVER=smtp
MAIL_HOST=mailtrap.io
MAIL_PORT=2525
[email protected]
MAIL_PASSWORD=xxxxxx
MAIL_ENCRYPTION=null

But in the first little moment of truth trying to send a mail (3:30 mark), I get an authentication error: Swift_TransportException in AuthHandler.php line 181: Failed to authenticate on SMTP server with username "[email protected]" using 3 possible authenticators

Based on a little stackoverflow reading, I tried turning on 'access to less secure apps' in my gmail settings, but no change in the error. (And the other posts about this issue had other factors that made a fancier problem than mine).

Nothing jumps out at me from laravel.log (below)- any ideas?

This is how I managed to fix this issue. first allowed 2 step verification and click this.

enter image description here

Then find this at the bottom and create an app password

enter image description here

Now add this in env

MAIL_MAILER=smtp
MAIL_HOST=smtp.gmail.com
MAIL_PORT=465
[email protected]
MAIL_PASSWORD="your app password"
MAIL_ENCRYPTION=ssl
MAIL_FROM_ADDRESS="[email protected]"
MAIL_FROM_NAME="${APP_NAME}"

Add your app app password previously generated instead of "your app password"

I know this is too late to answer, but I solved this issue by adding double quotes to the password like so:

MAIL_PASSWORD="yourpasswordgoeshere"

This will not work as of May 30, 2022 checkout here https://support.google.com/accounts/answer/6010255?hl=en&authuser=6 Thanks @sarout for pointing this out.

Did you turn on the "Allow less secure apps" on? go to this link

https://myaccount.google.com/security#connectedapps

Take a look at the Sign-in & security -> Apps with account access menu.

You must turn the option "Allow less secure apps" ON.

If is still doesn't work try one of these:

And change your .env file

MAIL_DRIVER=smtp
MAIL_HOST=smtp.gmail.com
MAIL_PORT=587
[email protected]
MAIL_PASSWORD=xxxxxx
MAIL_ENCRYPTION=tls

because the one's you have specified in the mail.php will only be used if the value is not available in the .env file.

I also got the same error-

  1. Make sure less secure app access is enabled in your gmail account https://myaccount.google.com/security#connectedapps
  2. Put double quotes to the password "password" in .env file

These solutions worked for me.

If you still get this error when sending email: "Failed to authenticate on SMTP server with username "[email protected]" using 3 possible authenticators"

You may try one of these methods:

Go to https://accounts.google.com/UnlockCaptcha, click continue and unlock your account for access through other media/sites.

Use double quote for your password: like - "Abc@%$67eSDu"

Change the .env file as follow

MAIL_DRIVER=smtp
MAIL_HOST=smtp.googlemail.com
MAIL_PORT=587
[email protected]
MAIL_PASSWORD=password
MAIL_ENCRYPTION=tls

And the go to the gmail security section ->Allow Less secure app access

Then run

php artisan config:clear

Refresh the site

I had the same problem and I've already tried everything and nothing seemed to work until I just changed the 'host' value in config.php to:

 'host' => env('smtp.mailtrap.io'),

When I changed that it worked nicely, somehow it was using the default host " smtp.mailtrap.org" and ignoring the .env variable I was setting.

After making some test I realize that if I placed the env variable in this order it would worked as it shoulded:

MAIL_HOST=smtp.mailtrap.io


MAIL_DRIVER=smtp


MAIL_PORT=2525


MAIL_USERNAME=xxxx


MAIL_PASSWORD=xxx


MAIL_ENCRYPTION=null

Nothing wrong with your method, it's a G-mail security issue.

  1. Login g-mail account settings.

  2. Enable 2-step verification.

  3. Generate app-password.

  4. Use new-generated password in place of your real g-mail password.

Don't forget to clear cache.

php artisan config:cache.
php artisan config:clear.

MAIL_DRIVER=smtp
MAIL_HOST=mailtrap.io
MAIL_PORT=587
[email protected]
MAIL_PASSWORD=generatedAppPassword
MAIL_ENCRYPTION=tls
