Worked on the goauthentik/authentik repository to deliver OpenID Connect back-channel logout support by introducing a dedicated 'logout+jwt' token type. This feature enhanced compliance with the OIDC specification by leveraging the JWT 'typ' header to explicitly distinguish logout tokens, following cross-JWT guidance. The implementation improved the security and auditability of logout flows, ensuring that token typing is both explicit and verifiable. Using Python for backend development, the work focused on OAuth2 and JWT handling, addressing interoperability and compliance challenges. The update also highlighted potential breaking changes for clients relying on previous token type validation, reflecting careful attention to integration impacts.
