1. An authentication device comprising:
a memory configured to store instructions; and
at least one processor configured to execute the instructions to:
extract first biological information of an authentication target from a first image, the authentication target being moving toward an exit of a predetermined area, the first image including the authentication target captured by a first image device;
extract, as candidate information of the authentication target, one or more sets of registrant information from a storage by performing a first authentication using the first biological information, the storage storing a plurality of sets of registrant information about a plurality of registrants to be authenticated;
extract second biological information of the authentication target from a second image, the second biological information being different type from the first biological information, the second image being an image by capturing the authentication target moving in the predetermined direction after the first image is captured, the second image captured by a second image device, the second image device capturing a still image;
determine, as a second authentication, whether to authenticate the authentication target by comparing the second biological information and one or more sets of biological information of being included in one or more sets of candidate information and the same type as the second biological information; and
adjust an imaging time when the second image device captures the second image so as to output a authenticate result before the authentication target arrives at the exit using a moving speed of the authentication target.
