Abstract
An electronic device is provided. The electronic device includes a memory storing first authenticated fingerprint information, and a processor configured to obtain first fingerprint information corresponding to a first input, compare the first fingerprint information with the first authenticated fingerprint information during a first user authentication, perform a designated function when the first authenticated fingerprint information belongs to a first reference, temporarily store the first fingerprint information when the first authenticated fingerprint information belongs to a second reference, obtain second fingerprint information corresponding to a second input during a second user authentication, compare the second fingerprint information with the first authenticated fingerprint information during the second user authentication when the second input satisfies a designated reference in relation to the first input, store the temporarily stored first fingerprint information as second authenticated fingerprint information when the second authenticated fingerprint information belongs to the first reference, and perform the designated function.
