Adaxes Self-Service Client is a lightweight application that integrates with the Windows and macOS login screen to give users a secure link for resetting their Active Directory or Entra ID passwords without administrator involvement. It opens a restricted browser session to the Adaxes self-service portal, preventing users from navigating outside the password-reset workflow. The client supports offline and remote scenarios, allowing password changes even without active network connectivity, and can notify unenrolled users to register for self-service.
