Features / Passkeys
Use authenticator model identifiers as one input to a WebAuthn/passkey policy where the implementation exposes and validates the relevant attestation data.
Explore the design intent, review practical decisions and validate exact behavior against your deployed configuration.
Why it matters
Organizations with device requirements may need to distinguish authenticators beyond simply allowing passkeys. AAGUID filtering is useful only when the signal is available and interpreted correctly.
Design intent
Specify allow and deny lists deliberately, decide how missing or untrusted identifiers are handled, and verify attestation and user-verification settings together. Avoid treating an identifier alone as proof that every device posture requirement is met.
Worked scenario
A passkey enrollment is accepted only when the authenticator satisfies the organization’s configured policy and the needed signals can be validated.
Boundary to verify
Confirm enforcement at the relevant server, API, resource or operational decision point. A hidden button or an informative dashboard is not, by itself, an authorization control.
Practical path
Use these stages as a review guide. Exact settings and enforcement points depend on the configured deployment and connected systems.
Identify the actor, target resource and operation that aaguid filtering for passkeys is meant to govern.
Specify allow and deny lists deliberately, decide how missing or untrusted identifiers are handled, and verify attestation and user-verification settings together. Avoid treating an identifier alone as proof that every device posture requirement is met.
A passkey enrollment is accepted only when the authenticator satisfies the organization’s configured policy and the needed signals can be validated. Also test the path that should be denied, deferred or sent for review.
Check that the resulting state is understandable and that the decision can be investigated later. For audit-enabled operations, confirm the relevant actor and context are captured.
Before rollout
A capability is easier to operate when ownership, failure behavior and verification are defined upfront.
This page describes a design approach based on WebFrolic’s documented product model. Verify feature availability and exact behavior in your environment before relying on it for a control requirement.

Evaluate with your scenario
Share the identities, resource boundary and decision you want to test. The walkthrough can focus on the relevant behavior rather than a generic feature tour.
