ChatGPT doesn't allow me to login suddenly

Hello there. For about two weeks I’ve tried logging in into my ChatGPT account (not this one), but it always says that I tried logging using a password and it’s not the way I signed in. I tried other ways to login, but impossible (it says the same). I also tried to login with an alternative account, but it says that I still tried logging in with my main account. I even tried resetting cache and all that, but it’s impossible. Help, please.
