I used these settings in joomla mail settings

Mailer: smtp
SMTP Authentication: yes
SMTP Security: SSL
SMTP Port: 465
SMTP Username: My gmail full address
SMTP Password: My gmail password
SMTP Host: smtp.gmail.com

Answer 1

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
