• a user authentication input configured to receive information from the user;
• a user interface configured to convey information to the user;
• and
• a processor configured to receive a user authentication input at the mobile electronic device via the user authentication input, cache the authentication input and, while the authentication input remains cached, authenticate the user to use the device via the authentication input, open the FIDO compliant application, and provide the cached authentication input to the FIDO compliant application to open an authenticated session of the user on the FIDO compliant application.

A method of enabling user access to a locked FIDO (fast identification online) compliant application on a locked mobile electronic device, the method comprising:

• receiving user authentication input at the mobile electronic device;
• authenticating the user to use the mobile electronic device via the authentication input and unlocking the mobile electronic device;
• and
• prior to additional user input if any, opening the FIDO compliant application and providing the same authentication input to the FIDO compliant application to open an authenticated session on the FIDO compliant application.
