iOS or Android update resets fingerprint login and KEY asks for master password instead
After a Operating System update on an Apple IOS or Android device, the fingerprint login is reset and F-Secure KEY now asks for master password to login.
After an Operating system update that has reset the fingerprint login, you will have to login one time using your master password. After you have logged in with your master password you can continue to login using your fingerprint. If you have forgotten your master password, you can use the "Forgot Master Password?" to recover it.
