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:

Go to https://accounts.google.com/UnlockCaptcha , and click continue and unlock your account for access through other media/sites.
Use double quote in your password: "your password"

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.

Question 2

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?
