When you're not using F-Secure KEY on either your computer or mobile device, it's a good idea to use the lock to add an extra layer of security.
To lock KEY:
In the menu, click Lock.
To unlock KEY:
Type in your master password.
Note: On your computer, F-Secure KEY locks itself automatically by default KEY after five minutes. You can set the time intervals for when KEY locks itself in Settings > General. The time intervals are 5 minutes, 30 minutes, 60 minutes, 10 hours, and one week.
