Why should I confirm email if I use Google Auth?

Why should I always confirm email if I use Google Auth for signing in on trello.com?

For the last few weeks when I try to log in on Trello with a Google button, Im getting a message with email confirmation. I guess If I use Google Auth that must means my email adress is already comfirmed, is not?

Is this a bug or a new account protection system?

Hi @3via , welcome to the Community!

For sign-ins using the "Continue with Google" button, we're sending verification codes via email. Once you enter the code, it should stay validated for the rest of your browser session. If you happen to restart your computer or close out of your browser entirely, you might be asked to enter a new verification code. Otherwise, it should stay verified while your browser is open.

Cheers,
Daniel
