FIDO2 match criteria fields lists the match criteria fields used in this policy; for descriptions of valid values, refer to the FIDO Registry.

FIDO2 policy configuration fields
Field	Type	Description
allowSelfAttestation	boolean	Attestation is used to cryptographically prove that a user has a specific device model at registration time. It is a keypair burned into the device at manufacturing time that is specific to a device model. During registration, the generated credentials are signed with the attestation private key and the service that registers the user can verify that the credentials came from the device. The allowSelfAttestation flag controls whether the RelyingParty accepts self-signed certificates at registration instead of an attestation certificate that chains back to some root certificate.

allowSelfAttestation

boolean

Attestation is used to cryptographically prove that a user has a specific device model at registration time. It is a keypair burned into the device at manufacturing time that is specific to a device model. During registration, the generated credentials are signed with the attestation private key and the service that registers the user can verify that the credentials came from the device.

The allowSelfAttestation flag controls whether the RelyingParty accepts self-signed certificates at registration instead of an attestation certificate that chains back to some root certificate.

Field	Type	Description
FIDO2 match criteria fields
aaguid	Array of strings	Each FIDO2 authenticator model has an attestation ID (AAGUID) that uniquely identifies the type of authenticator. Valid values: UUIDv4 format Example: ["7a98c250-6808-11cf-b73b-00aa00b677a7"]
attestationCertificateKeyIdentifier	Array of strings	FIDO U2F authenticators do not support AAGUID, however they use attestation certificates to uniquely identify the authenticator model. Valid values: Hex string, Format: [0-9a-f]+ Example: ["1434d2f277fe479c35ddf6aa4d08a07cbce99dd7"]
userVerification	Array of strings	Describes the methods and capabilities of a FIDO2 authenticator for locally verifying a user. Valid values: PRESENCE_INTERNAL FINGERPRINT_INTERNAL PASSCODE_INTERNAL VOICEPRINT_INTERNAL FACEPRINT_INTERNAL LOCATION_INTERNAL EYEPRINT_INTERNAL PATTERN_INTERNAL HANDPRINT_INTERNAL PASSCODE_EXTERNAL PATTERN_EXTERNAL NONE Example: ["FINGERPRINT_INTERNAL", "PASSCODE_INTERNAL", "PASSCODE_EXTERNAL"]
keyProtection	Array of strings	Describes the method an authenticator uses to protect the private key. Valid values: SOFTWARE HARDWARE TEE SECURE_ELEMENT REMOTE_HANDLE Example: ["SOFTWARE"]
authCertLevel	Array of strings	Describes the level of Certification. (For more information, refer to the FIDO documentation on authenticator certification levels.) Valid values: NOT_FIDO_CERTIFIED FIDO_CERTIFIED FIDO_CERTIFIED_L1 FIDO_CERTIFIED_L1_PLUS FIDO_CERTIFIED_L2 FIDO_CERTIFIED_L3 FIDO_CERTIFIED_L3_PLUS Example: ["FIDO_CERTIFIED_L1"]
minAuthenticatorVersion	Integer	Describes the minimum version of the authenticator. Example: 2
