Abstract
A computer system and method for authenticating a user device associated with a user during the process of logging into a server. The server can generate input requests each of which is valid only during a defined time period, and displays said input requests in succession in a login screen. The user device reads in the input request displayed at the time of the login and calculates a response by using said input request, the password of the user device, and the current time. The user device transmits the calculated response to the login screen and the response is transmitted by the login screen to the server. The server confirms the authentication when the response calculated by the server matches the response transmitted by the user device.
