By default, if you key in the wrong password of the bal user for more than 3 times, the bal user account will be locked for 10 minutes.
To change the setting, navigate to: Certificates & Security > Admin WUI Access.
Session Management must be enabled in order to allow this setting.
Note that only the bal user is allowed to be automatically unlocked. Local users must instead be manually unlocked by a user with administrator privileges.
If you have forgotten the bal login password, you can reset it using the console. For more information, refer to the following article: https://support.kemptechnologies.com/hc/en-us/articles/115003713826-How-to-Reset-and-Change-The-Bal-User-Password
