Reply To: gmail is blocking M1 emails

There is a better and secure way to give non-Google apps “SMTP access” to the Google account. You can generate an “app password” and use that in ELK. It works as follows:

1. Sign in to your Gmail account security
2. Enable 2-step verification.
3. Create an App password
4. Use this password for SMTP.

The process to generate and use app password is documented here:

App password works with ELK. It is very secure. Also, it only allows SMTP access to the Google account and NOT the complete access to Gmail/Google account.
Another problem in using “Allow less secure apps” option is that this option get disabled after some time, auto-magically. Unless you check, you don’t know that this option has been disabled.
