An Authenticator is not required to initiate a password reset, Brooklyne, you only need to be able to answer some account specific questions and have access to the registered e-mail.
Though I see where you reset your password I also see a previous attempt that, unless you have some secret wormhole technology, is likely not your doing.
I'd recommend that you check your system for possible compromise then change your e-mail password or perhaps consider changing the e-mail address for your account.
