You'll need to enable 2FA in google and use the following settings.

You will need to generate an application specific password after configuring 2 factor authentication and use as password in the SMTP configuration

MAIL_DRIVER=smtp
MAIL_HOST=smtp.gmail.com
MAIL_PORT=587
MAIL_USERNAME=<<your email address>>
MAIL_PASSWORD=<<app password>>
MAIL_ENCRYPTION=tls
