Credential stuffing is the common form of a security breach that attacker use nowadays. Although Drupal is a secure platform, still the chances of exploitation are there.

And if the user tries to log in from more than one browser at the same time then either he will be asked to log out from the previous browser before logging in another browser or abort their new login session.
