As stated above, the addition on an authenticator is an absolute sure sign your email is compromised.
I do see you've changed it. While I normally recommend a change to something a bit different, hopefully this will address your issue. Make absolutely certain you are not reusing passwords, that's very high risk.
I also wouldn't use that email anywhere else.
