Title
FAL3 With an RP-Bound Authenticator
Control
The home agency IdP authenticates the PIV identity account using an authenticator bound to the account, and then creates an assertion that is flagged as FAL3 and using an RP-bound authenticator.
When the RP receives the assertion, it processes it as usual and sees the FAL3 flag. The RP looks up the bound authenticator associated with the RP Subscriber Account and prompts the subscriber for this authenticator. When the authenticator has been verified, the RP creates a secure session at FAL3.
