An objective is to provide a terminal device, an authentication information management method, and an authentication information management system for securing a security level of authentication information while maintaining the convenience for a user. A mobile device (10) determines whether communication with a wearable device (30) is possible and determines whether the mobile device (10) is able to communicate with an authentication server (20). When it is determined that communication between the mobile device (10) and the wearable device (30) is possible and communication between the mobile device (10) and the authentication server (20) is possible, the mobile device (10) transmits identification information corresponding to the wearable device (30) to the authentication server (20), requests the authentication server (20) to transmit authentication information, receives the authentication information from the authentication server (20) in response to the transmission request, and transmits the received authentication information to the wearable device (30). |
