Relying-party binding
Bind credentials and challenges to the configured verifier.
Use verifier-bound credentials instead of reusable shared secrets.
2AYE implements passkey registration, authentication, recent-user-verification checks, credential revocation, and policy-driven passkey step-up.
- Relying-party binding
- User verification
- Credential lifecycle
What you can evaluate
Phishing resistance through cryptographic binding.
User verification
Record whether the authenticator verified the user.
Credential lifecycle
List, rename, and revoke registered passkeys.
Step-up enforcement
Refuse stale, revoked, or wrong-principal authentication.
Follow Passwordless from identity to evidence.
Each consequential action moves through the same six control points. See where 2AYE evaluates authority, requests human review, and preserves the outcome.
- 01IdentityWho or what is acting
- 02IntentSigned purpose and limits
- 03PolicyDeterministic evaluation
- 04ApprovalA named human when required
- 05ExecutionSingle-use grant, redeemed at the resource
- 06EvidenceReceipt joined to the audit chain
A practical adoption path
Start with one consequential workflow. Prove the boundary before expanding.
Assess
Document the environment, threat model, and integration boundary.
Design
Select protocols, signals, policies, and failure behavior.
Validate
Test vendor-specific APIs, tenant isolation, and abuse paths.
Release
Mark available only after deployed end-to-end verification.
