  • Publication number: 20250080527
    Abstract: The invention is a method for managing a remote server that assigns to a user agent (30) a session reference (31) and a user authentication request. The user agent (30) delegates the authentication request to an identity wallet (20) that sends a proof (21) of identity to the remote server (10). The user agent and the identity wallet are two separate devices, one of which generates and displays an ephemeral confirmation token (60) and sends to the remote server a control token (65) generated from the ephemeral confirmation token. The other of said devices gets a code (61) entered by the user then communicates with the remote server for contributing to a checking of the code by using the control token. The remote server grants rights associated to the session reference only if the proof of the identity is valid and if said checking is successful.
