The present disclosure discloses a method, device and system for negotiating authentication mode. A first negotiation request carrying an authentication mode supported by a terminal is sent to an authentication server, so that the authentication server determines and sends an authentication mode supported by both the authentication server and the terminal, where the authentication mode is determined according to an authentication mode supported by the authentication server and the authentication mode supported by the terminal in the first negotiation request. The authentication mode supported by both the authentication server and the terminal is received by the terminal from the authentication server. Therefore, according to the disclosure, a common authentication mode supported by both the authentication server and the terminal is negotiated before the authentication is performed. |
