Periodic reauthentication of subscriber sessions SHALL be performed, as described in Sec. 5.2 . A definite reauthentication overall timeout SHALL be established, which SHOULD be no more than 24 hours at AAL2. The inactivity timeout SHOULD be no more than 1 hour. When the inactivity timeout has occurred but the overall timeout has not yet occurred, the verifier MAY allow the subscriber to reauthenticate using only a successful password or biometric comparison in conjunction with the session secret , as described in Sec. 5.1 .
