Title

Changing the Federated Identifier

Control

To facilitate recovery of an account when a federated PIV identity account can no longer be used, an RP MAY change the federated identifier bound to an RP subscriber account in limited circumstances to be recorded in the trust agreement:

• A change of PIV IdP for the home agency of a PIV identity account

• A change of configuration that alters the subject identifier or issuer identifier portion of the federated identifier for a PIV identity account

When the federated identifier is changed, the RP SHALL make the RP subscriber account inactive and SHALL require a succesful federated authentication using the new federated identifier before considering the RP subscriber account active again. The RP SHALL NOT allow the previously used federated identifier to be used to access the account.

The RP SHALL make a record of any such change, including the identifiers of all affected RP subscriber accounts at the time of the change. The RP SHALL provide notice to the subscriber when a federated identifier is bound or unbound to an RP subscriber account.

The RP SHALL NOT convert an RP subscriber account to be available using local authentication.
