1. An electronic device comprising:
a fingerprint sensor;
a display comprising a touch sensor;
at least one processor including processing circuitry; and
memory storing instructions that, when executed by the at least one processor individually or collectively, cause the electronic device to:
obtain a first touch input of a user to the display through the touch sensor,
perform authentication for the user, based on a fingerprint image and registered fingerprint information, the fingerprint image being obtained through the fingerprint sensor when the first touch input is obtained,
identify, based on the authentication for the user being successful, whether the fingerprint image satisfies a first condition for updating the registered fingerprint information,
identify whether an intensity of the first touch input is greater than a threshold intensity set to determine whether a touch input to the display is inputted by the user's finger without a foreign object between the user's finger and the display, and
update the registered fingerprint information using the fingerprint image, based on identifying that the fingerprint image satisfies the first condition and the intensity of the first touch input is greater than the threshold intensity.
