Abstract: A security authentication system for a website provides a safe login without having to directly enter an ID and a password on a user device requesting login to the website. A first user device receives one-time use authentication information from a second user device after the second user device received the one-time use authentication information from an authentication server without the authentication server receiving user login authentication information from the second user device. A request is transmitted to the authentication server based on the one-time use authentication information and the user login authentication information. In response to the request, one-time password (OTP) information is received from the authentication server. The OTP information is presented by the first user device, such that the OTP information can be entered into the second user device and used in a request to log in to the website.
