An electronic device is provided. The electronic device includes a touchscreen display, a pressure sensor positioned to sense external pressure against the display, a fingerprint sensor positioned to detect a fingerprint on at least a portion of the display, a processor electrically coupled to the display, the pressure sensor, and the fingerprint sensor, and a memory electrically coupled to the processor, in which the memory stores at least one registered fingerprint. The processor is configured to sense pressure of a user's finger against the display using the pressure sensor, upon sensing of the pressure, activate the fingerprint sensor, detect a fingerprint of the finger using the fingerprint sensor, determine whether the detected fingerprint is matched with any of the at least one registered fingerprint, and perform a preselected function without further requiring authentication, when the detected fingerprint is matched with any of the at least one registered fingerprint.
