Key Generation Process

The key generation process for Azure AD passkeys involves several essential steps to guarantee secure and efficient authentication.

First, you’ll engage in enrollment and registration by directing yourself to ‘aka.ms/mysecurityinfo’ to set up a security key, typically using a QR code. After authenticating with a Temporary Access Pass (TAP), you’ll choose your security key method, tap the key, and set your PIN. Once registered with Microsoft Entra ID, you’ll name your security key and complete the process.

During this phase, your security key vendor provides a unique Authenticator Attestation GUID (AAGUID), a 128-bit identifier that distinguishes key types. This AAGUID needs to be unique and consistent across identical keys.

Provisioning can also be managed via the Microsoft Graph API, where administrators create user credentials, guaranteeing a smooth deployment of FIDO2 security keys.

To enhance security, organizations must update their passkey policies to include approved AAGUIDs, and establish Conditional Access Policies to enforce security key usage. By defining authentication strength, you guarantee that Passkeys (FIDO2) are recognized as valid authentication methods.

How Authentication Works

Once you’ve registered your security key, you can start the authentication process through Azure AD. Begin by entering your username on the Microsoft Entra sign-in page. When prompted, select your sign-in method, choosing the Azure AD passkeys option. Your device will detect the FIDO2 security key, leading you to save the passkey securely.

Next, Microsoft Entra ID sends a nonce to your device, which signs it using your private key stored in the secure enclave of the FIDO2 security key. This signed nonce is sent back for validation. Microsoft Entra ID verifies it using your registered public key. If validation is successful, a primary refresh token (PRT) is created and returned to your device. This process emphasizes the importance of multifactor authentication (MFA) in enhancing security.

The PRT, encrypted with your device’s transport key, allows access to on-premises resources and applications. This entire authentication process enables secure, passwordless authentication, minimizing risks associated with traditional passwords. Enhanced security against phishing attacks makes this method even more reliable for users.

Administrators can manage this process through the authentication methods policy, specifying who can use passkeys and enforcing conditional access for sensitive resources. By utilizing Azure AD passkeys, you enhance your user authentication experience with robust security.

Biometric and PIN Usage

Biometric and PIN usage offers you flexible and secure options for signing in to your accounts. With biometric recognition, like face and fingerprint scanning, you can authenticate quickly and conveniently. This data stays on your device, enhancing your private key security and making it resistant to phishing attacks.
