When I was asked about a recovery e-mail address for my Gmail account I added my Yahoo account home e-mail address. This has become my primary (user name for my Gmail account and has locked up Google on my new phone, and my Gmail account....can't open to get in and fix anything. Afraid to delete old account since it is attached to my new phone.


The way to change the primary email address of a Google account is by canceling the Gmail address this will remove Gmail from the account and also could affect any other service that use a Gmail address as the user ID. But you could still get back your Gmail address.
