The Login Settings page contains options for user blocking and login limitations.
The default Login Setting is:
Block user on login failure: Enabled
Block timeout: 5 minutes
Maximum number of failed logins: 3
To configure login settings:
Click Security > Login Settings.
To block users for failed logins, select the Block user on login failure checkbox, then configure the parameters.
Block timeout: Select the time period that users with failed logins will be blocked from logging in.
Maximum number of failed logins: Enter the number of failed login attempts that users can make before they are blocked.
To automatically logout users after an idle period, select a time in the Idle timeout period field. To allow idle users to remain logged in, select "infinite."
Select "Prevent concurrent login with same username" to prevent logins by more than one user with the same username. This setting does not apply to the default admin user.
