When to Use This Skill
- Implementing Proof-of-Possession (PoP) tokens with DPoP or mTLS
- Configuring Pushed Authorization Requests (PAR) for front-channel parameter security
- Setting up JWT Secured Authorization Requests (JAR) for tamperproof authorize requests
- Building FAPI 2.0 compliant authorization servers
- Choosing between DPoP and mTLS for sender-constrained tokens
- Configuring APIs to validate proof-of-possession tokens
- Meeting regulatory or industry security requirements (open banking, e-health, e-government)
