An electronic apparatus comprising: a first camera disposed on one surface of the electronic apparatus; a second camera disposed on the one surface; and a processor, connected to the first camera and the second camera, configured to: obtain a request associated with biometric authentication; obtain, based on the request, at least one first image using the first camera having a first field of view, FOV; obtain, based on the request, at least one second image using the second camera having a second FOV corresponding to a part of the first FOV; identify a first external object associated with the biometric authentication from the at least one first image; identify a second external object associated with the biometric authentication and corresponding to a part of the first external object, from the at least one second image; provide a first notification indicating that the first external object is not identified from the at least one first image and the second external object is not identified from the at least one second image, when the first external object is not identified from the at least one first image and the second external object is not identified from the at least one second image; provide a second notification for positioning the second external object in the second FOV, when the first external object is identified from the at least one first image and the second external object is not identified from the at least one second image; and perform authentication using biometric information corresponding to at least a part of the second external object, when the second external object is identified from the at least one second image, wherein the second notification includes information guiding at least one of a movement upward, a movement downward, a movement to the left, or a movement to the right and the information is determined based on the location of the first external object identified from the at least one first image. a first camera disposed on one surface of the electronic apparatus;
