I'm trying to add second gmail account, but my credentials were rejected.

An email server was detected, however your credentials were rejected.

But my credentials are correct. So whats the solution?

Hi,
please double-check if you’re using the right password and login, check with your online login window to your account.
What version of eM Client are you using?

Thank you,
Paul.

Hi Paul,

6.0.19861.0 and my login/password is ok too. Diagnose/fix doesn’t help either.
Yahoo is working fine.

Thanks !

Hi again,
can you please check if your gmail account doesn’t have enabled two step verification?
If so you need to generate app specific password and use that password instead of your regular password.

Paul.

Thanks Paul !

Sorted.
