Sounds like your account name is listed in some leaked DB.
A dozen or so ruskies/BR's skiddies bought the list, and run a script on it. You and a few thousand accounts have changed password, so they're running the non-autheticated accounts through a simple Dictionary script to try commonly used passwords.
Protip: if your password is listed here: https://en.wikipedia.org/wiki/List_of_the_most_common_passwords
then fucking change it.
The authenticator bullshit is a doubleedged sword: the ruskies don't count on it much, but the BR's have an habit of making login attempts as frequently as possible until the victim gives up and turns that shit off. Nothing you can do except change the password, but on the off chance you got some RAT listening on your computer, router, try changing at a friends computer.
DON'T log on your own computer. Wait a few days, see if the authetnticator stops hammering you with requests.
If it does, congratulations: you not only sucesssfully changed the password, but you've also proven something's listening on your PC or router. Bleach both.
