Answer 1

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
MAIL_USERNAME=yourgmailid@gmail.com
MAIL_PASSWORD=generatedAppPassword
MAIL_ENCRYPTION=tls

If you still get this error when sending email: "Failed to authenticate on SMTP server with username "youremail@gmail.com" using 3 possible authenticators"

You may try one of these methods:

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

2. Using a double quote password: "your password" <-- this one also solved my problem.

Answer 6

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
