I received this message in my same named yahoo email n......email@example.com. I also received this message in text to my cell phone.
Sign-in attempt was blocked n......firstname.lastname@example.org Someone just used your password to try to sign in to your account. Google blocked them, but you** should check what happened.
I am not able to recover the account using the security question. I don't remember ever setting up this n.......email@example.com account. It seems like someone is trying to use a Gmail account using the same account name as my yahoo mail account. I have gotten this message in the past as well.
