I’m trying to add a recovery number to an old google Gmail email but the only way I have access to the email is from the mail app (NOT the Gmail app or for google itself) my question is how do I do that when it won’t show me the sign in and security button? Please help !!

another question Is there a way to reset the password without logging out or knowing the old password? (The email is so old it does not have a recovery email or 2 times authentication it’s VERY old )
