1. An electronic device comprising:
a display;
a communication circuit;
memory storing one or more computer programs; and
at least one processor operatively connected to the display, the communication circuit, and the memory,
wherein the one or more computer programs include computer-executable instructions that, when executed by the at least one processor, cause the electronic device to:
receive, from an augmented reality (AR) device through the communication circuit in a state of being wirelessly connected to the AR device through the communication circuit, fingerprint candidate group data corresponding to fingerprints remaining on a front display of the electronic device captured by a camera of the AR device,
determine authentication validity of a fingerprint candidate area by matching the fingerprint candidate group data with a fingerprint authentication template registered in the electronic device, and
transmit, to the AR device through the communication circuit, a security level obtained by evaluating a security risk of the fingerprints remaining on the front display of the electronic device as a result of the authentication validity, such that guidance information relating to the fingerprints remaining on the front display is output.
