23 Commits • 9 Features
Jun 1, 2025June 2025 focused on strengthening security, improving 2FA workflows, and hardening platform reliability across Windows and browser environments in the keycloak/keycloak repository. The team delivered extensive WebAuthn/Passkeys integration across authentication flows with recovery codes, upgraded the WebAuthn library, and expanded test coverage. Passkeys were extended to the Organization Authenticator, the original Passkeys Conditional UI Authenticator was deprecated, and login without a password credential was enabled. The browser 2FA flow was clarified by renaming the default flow, accompanied by 2FA documentation updates. Several reliability and cross-platform fixes were implemented to improve UX and stability in real-world environments. In addition, data correctness and policy hygiene were improved through targeted fixes in brute force handling, createTimeout representation, and policy tab consistency.
