Hi. Last month Google and several other applications notified me that my old passwords had been leaked. Yesterday I received a "codeforces new login" message from my email. My personal information, password and email address were reset.

Surprisingly, I wasn't automatically logged out of my account, although I can't log back in with my old password.

I recommend guys using different passwords for different apps. This way, even if a password leakage occurs, your other apps will still be protected.
