Identification and/or authentication method

A computer-implemented authentication method allows a user having a personal electronic device (PED) to login to a recipient system. The user establishes an account on an authentication server, provides personal information to the PED, and uniquely identifies the user's PED. The authentication method establishes a unique token ID for the user. Upon interacting with the recipient system, the user is prompted for his token ID. The recipient system communicates with the authentication server to request the user's information. The authentication server sends an authentication request to the user's PED, which prompts the user for a decision to proceed or not. The user, if deciding to proceed with authentication, selects a subset of the user's personal information that is then sent to the recipient system by the PED, the recipient system authenticating the user thereby.
