[Login] Am I GETTING HACKED or is this a BUG? Unable to login.

Today I tried to login to my account, but it gave me a credential error, even after checking and rechecking what i typed was indeed my correct username and password, and also tripled checked that my keyboard settings were correct. THEN I was able to sign in again by changing my password then signing in with the new password. This whole week, I have been playing almost everyday and login in without any issues, until now.

ok very strange, BUT THEN.....

JUST NOW, I was automatically logged out, saying my session has ended. When I tried to login again, IT ONCE AGAIN DID NOT WORK, giving me a credentials error. I checked many times to make sure my username/password did not have any typos. I had to request a password change AGAIN, then was able to log in with that new password.

What is going on am I getting hacked? Or is this a bug?
