Failed to authenticate with SMTP server error using gmail

Question

I am trying to set up email for my first laravel project and was thrilled to have laracast there: https://laracasts.com/lessons/mailers

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

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

.env has (x added for anonymity) - laracast does not use us MAIL_USERNAME and MAIL_PASSWORD, but they are updated for a good rating, assuming that I come from there later:

 MAIL_DRIVER=smtp MAIL_HOST=mailtrap.io MAIL_PORT=2525 MAIL_USERNAME=[e-mail] MAIL_PASSWORD=xxxxxx MAIL_ENCRYPTION=null 

But in the first moment of truth, trying to send mail (mark 3:30), I get an authentication error: Swift_TransportException in the AuthHandler.php line 181: Authentication on the SMTP server with the username " [e-mail] " failed, using 3 possible authenticator

Based on a small read on the stack, I tried to enable "access to less secure applications" in gmail settings, but no changes in the error. (And other reports about this issue were related to other factors that caused a more serious problem than mine).

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

Answer 1

Have you enabled "Allow less secure apps"? follow this link

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

Take a look at the Login and Security menu → Applications with account access.

You must enable the "Allow less secure applications" option.

If still not working, try one of them:

• Go to https://accounts.google.com/UnlockCaptcha and click "Continue" and unlock your account to access through other media / sites.

• Use a double quote in your password: "your password"

And change your .env file

 MAIL_DRIVER=smtp MAIL_HOST=smtp.gmail.com MAIL_PORT=587 MAIL_USERNAME=[e-mail] MAIL_PASSWORD=xxxxxx MAIL_ENCRYPTION=tls 

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

Answer 2

Your method is okay, this is an email security issue.

1. Email account login settings.

2. Enable two-step verification.

3. Create application password .

4. Use the new generated password instead of your real email password.

Remember to clear the cache.

 php artisan config:cache. php artisan config:clear. MAIL_DRIVER=smtp MAIL_HOST=mailtrap.io MAIL_PORT=587 MAIL_USERNAME=[e-mail] MAIL_PASSWORD=generatedAppPassword MAIL_ENCRYPTION=tls 

Answer 3

I had the same problem, but when I ran the following command, it was fine:

 php artisan config:cache 

Answer 4

Here is how I solved this problem:

• Modify the .env file as follows

2. Never forget to restart the server after modifying the .env file

Answer 5

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

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

When I changed this, it worked well, somehow it used the default host "smtp.mailtrap.org" and ignored the .env variable that I set.

After some testing, I understand that if I put the env variable in that order, it would work the way it should:

MAIL_HOST = smtp.mailtrap.io

MAIL_DRIVER = SMTP

MAIL_PORT = 2525

MAIL_USERNAME = xxxx

MAIL_PASSWORD = xxx

MAIL_ENCRYPTION = zero

Answer 6

I had this error:

"Authentication failed on the SMTP server with the username" [e-mail]. "Using 3 possible authenticators. LOGIN authorization returned Swift_TransportException: expected response code 235, but received code" 535 "with the message" 535-5.7.8 Username and password not found "accepted. More on 535 5.7.8 https://support.google.com/mail/?p=BadCredentials 75sm6289114otc.67 - gsmtp"

Maharjan's Milan answer solved my problem! Thanks dude.

Answer 7

If you still get this error when sending e-mail: "Failed to authenticate to the SMTP server with the username" [e-mail] "using 3 possible authenticators"

You can try one of the following methods:

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

Using the password in double quotes: "your password". & lt; - This also solved my problem.
