You could be logged off (or else logged out) in the TM ID authorization center, whose account is used to log in to Habr and Toaster, as well as token authorization to Freelance and My Circle. Do not worry, we are not hacked - this is a planned operation related to the relocation of the authorization center from the address id.tmtm.ru to account.habr.com .
For the convenience of logging into the site in the future, you can link GitHub or any social network. If you have not done this before, you will have to remember the password or complete a small quest to restore it. However, a periodic password change is one of the golden rules of information security. ')
Holiday greetings!
