    • Will reach out to Anoop to confirm whether this is still needed
  • #293 - PKCE & Nonce Security Considerations
    • PKCE is mandatory in FAPI2
    • For FAPI1, encourage use of PKCE in deployment and implementation advice

    • Will be updated in errata
  • #434 - Certification Team Query: error messages shown by OPs

    • Need text proposal
  • #443 - Missing Discovery Metadata for login_hint types and login_hint_token type: backchannel_endpoint_login_hint_token_values_supported
    • Brazil will only us id_token_hint so there is no longer need for this in Brazil
  • #282 - FAPI 2.0: x-fapi-* headers
    • Useful to have some headers standardized

  • #429 - FAPI Certification with Lodged Intent or RAR - User Consent vs Technical Process Certification.
