The account is locked when the user enters his/her password incorrectly more than five times or uses an incorrect Multi-Factor Authorization. The system will show you an error message saying: 'User is Locked'.
By default, the system unlocks itself after 5 minutes and the user can log in again with the correct credentials.
Once the account is locked, even if you add the correct email or password, you will need to wait until the account is unlocked. Please be aware that if you keep trying, the system will keep adding extra time for every attempt. So, If you cannot remember the password, please wait for 5 minutes, then go to the login page, and click on "Forgot your password".
