Login across devices with mobile biometric authentication.
Hey, here's an idea for login authentication.
For example when at desktop/ browser and logging in, you get a promt to verificate the login with your fingerprint on you mobile device. No need to type the master password, just use your fingerprint to authenticate the login via key. This service is used in few banking apps and payment apps.
It would help with security for the master password (which would also act as a backup), you would be able to log in everywhere with your biometrics data via F-Secure Key.
