Lock Out User Accounts

You can prohibit login when there are a certain number of consecutive failed attempts to login with an invalid user name or password.

Important: To increase security, we recommend you enable the setting(s).

You can configure the settings at following property window.

In the Project Explorer window, go to [Security] and click [Settings].
In the Properties window, click [Basic] tab.

[Lockout]

Select this check box to prohibit login when the number of consecutive failed attempts to login with an invalid user name or password reaches the number set in the [Number of Attempts] property.
Once login is prohibited, locked out users cannot log in even if they use a valid username and password.
All users with a security level less than the security level set in [Security Level for Unlock] are locked out.

Use one of the following methods to release the lock:

Wait for the time set in [Lockout Time (Min)] to elapse
Reboot the display unit
Login with a user that has a security level higher than the security level set in the [Security Level for Unlock] property
Transfer the project file

To increase security, we recommend you select this check box.

Note:

While users are locked out, the value of the source property (SecuritySettings.LockStatus) is ON.
If a user attempts to login while locked out, the login failure message "User account is locked" will display.
