Henrik Strath updated the authentication flows documentation in the keycloak/keycloak repository to reflect recent GUI changes, focusing on improving clarity and accuracy for developers. He revised the description of the 'Requirement' field, specifying it as a drop-down rather than radio buttons, and refined the definitions of 'Required', 'Alternative', 'Disabled', and 'Conditional' to reduce misconfigurations. Working primarily with adoc and leveraging his documentation skills, Henrik ensured the documentation now aligns with the current user interface. This update supports future feature development and onboarding by making authentication flow concepts more accessible and reducing the risk of errors for new and existing users.
