Qué comprueba
FIDO2 security keys provide phishing-resistant authentication but must be inventoried and managed throughout their lifecycle. Untracked keys may remain associated with departed employees or become lost without detection. Regular audits ensure only authorized keys are active and properly assigned to current users.
Valor recomendado
All registered FIDO2 keys inventoried with documented owner assignments and regular attestation reviews
Remediación
Review FIDO2 key registrations via Entra ID > Protection > Authentication methods > FIDO2 security key. Cross-reference registered keys with your hardware asset inventory and remove keys for departed users. Implement key registration policies that restrict allowed AAGUID values to approved vendor models.
