The purpose of the present invention is to make it possible to simplify the authentication information to be inputted by a user while securing safety. An information-processing device specifies the current conditions in which the user is situated. The information-processing device acquires the conditions in which the user was situated at the time of past authentication. When the user is currently in an authenticated state, the information-processing device simplifies the authentication information to be inputted by the user in accordance with the current and the past conditions. The information-processing device outputs information for prompting the input of simplified authentication information. |
