An electronic device may include a finger-operated input device, and a finger sensor carried by the finger-operated input device to sense a user's finger. The electronic device may also include a processor to perform at least one device function responsive to operation of the finger-operated input device. The processor may also acquire finger-enrollment biometric data of the user's finger from the finger sensor responsive to each of multiple operations of the finger-operated input device. The processor may further acquire finger-matching biometric data of the user's finger from the finger sensor responsive to a subsequent operation of the finger-operated input device, and authenticate the user based upon a match between the acquired finger-matching biometric data and the finger-enrollment biometric data.
