Abstract: The embodiments of the present disclosure relate to a method for unlocking administration authority and a device for performing authentication, and pertain to the technical field of computer information security. In the method, the authentication device receives authentication information sent by a plurality of member devices. The member devices include a mobile terminal or a wearable device. The authentication device performs a matching authentication of the authentication information by matching authentication information sent from a member device with authentication information prestored in an authorized authentication information list, and determines a distance between an authenticated member device and the authentication device. Then, the authentication device unlocks local administration authority if the number of authenticated member devices that are located within a predetermined distance threshold from the authentication device reaches a predetermined number threshold.
