On mobile devices, F-Secure KEY always asks you to enter your master password every time you launch the app by default. This works as an automatic lock, designed to give you an added layer of security.
You can set KEY to remember your master password when you access the app, if you'd rather access KEY without unlocking it every time.
To set KEY to remember your master password:
Open up the app.
Select the box Remember my Master Password on this device.
Once selected, KEY does not ask you for your master password any longer, unless you lock the app from the menu.
Note: If you allow KEY to remember your password on your device, we recommend that you use a screen lock on that device.
