Authentication of user accounts for students, faculty and staff of the University of Arkansas in Fayetteville (UAF) is handled by the UAF Identity Provider (IdP) service. An IdP service verifies user's identity by requiring a user name, password and a two factor authentication step (2FA) - an additional time limited security token usually obtained by a phone application.

Other schools within the University of Arkansas System (UASYS) use their own IdP services. IdP services for all schools within the UASYS are combined in a UASYS IdP Bridge. This bridge allows any student, faculty and staff within UASYS to log into the AHPCC clusters.

Users external to UASYS can access AHPCC clusters by using a guest account. A guest account is verified by an external IdP service.

All identities, regardless of whether verified by one of UASYS IdP's or the external IdP, have to have a matching active user account on the AHPCC cluster to allow access into the system. AHPCC account application
