Explain that first factor and other forms of second factor authentication is up to the developer as to how they want to implement it.
SurePassIdU2fSign
The Sign In Activity must extend SurePassIdU2fSignActivity. It must implement the following abstract methods.
...
Below is the code related to processing a FIDO U2F sign operation.

Upon successfully authenticating the user it should call

That method will perform all the necessary U2F operations.
