Description Paramvir jindal 2021-04-26 06:33:02 UTC

Even though Permanent Lockout is a feature of Brute Force Detection, it doesn't protect the account from exposing his/hers credentials.
Once the account is locked, the malicious actor can keep trying to login and will get informed the account is disabled once the password is correct.
