Instant Revocation of Service Principal Bearer Tokens with CAE

Microsoft documents how Continuous Access Evaluation can invalidate service-principal bearer tokens within minutes instead of waiting for their normal token lifetime to expire.

What changed

A client-credential token request can advertise the CAE client capability claim xms_cc with the value cp1. CAE-enabled workload-identity tokens can then be revoked when the service principal reaches high risk, is disabled or is deleted.

Technical details

CAE client capability for service-principal token requests
Automatic revocation when a service principal is high risk, disabled or deleted
Manual validation workflow for incident-response readiness

Why it matters

Service-principal bearer tokens normally remain usable until expiry. Rapid revocation provides an operational kill switch when a workload identity or its token is compromised.

Known limitations

The application requesting the token must support the CAE client capability
Workload identity protection and tenant prerequisites remain authoritative in the linked Microsoft article
