Account Lock

You can configure Full Disk Encryption to lock user accounts after a specified number of unsuccessful Pre-boot login attempts:

• Temporarily - If an account is locked temporarily, users can try to log on again after a specified time.
• Permanently - If the account is locked permanently, it stays locked until an administrator unlocks it.

Select one of these Actions to define if and when user accounts are locked:

Action	Description
Do not lock out users upon failed authentication.	Users are not locked out of their accounts if they try to log on unsuccessfully. This setting is not recommended.
Temporarily lock user account upon failed authentication attempts	After a configured amount of failed log on attempts (the default is 5), the user's account is temporarily locked.
Permanently lock user account upon failed authentication attempts	After a configured amount of failed log on attempts (the default is 10), the user's account is permanently locked.

Right-click an Action to edit the properties. You can also create custom Account Lock actions.
