Qué comprueba
Temporary Access Pass allows time-limited passcodes for onboarding users to passwordless credentials, but can serve as a backdoor if not properly restricted. TAPs that are configured with long lifetimes or reusable settings can be exploited by attackers who compromise the issuance process. The TAP policy should enforce short lifetimes, single-use restrictions, and limit issuance to authorized administrators.
Valor recomendado
TAP enabled with maximum lifetime of 1 hour, single-use only, restricted to authorized onboarding administrators
Remediación
Review the TAP policy in Entra ID > Protection > Authentication methods > Temporary Access Pass. Set the minimum and maximum lifetime to the shortest practical duration and enable one-time use. Restrict TAP issuance permissions to a limited set of administrators through role-based access controls.
