Abstract: The present disclosure relates to an electronic device capable of performing multimodal biometric authentication, and the electronic device may include a memory configured to store information; a plurality of sensors configured to receive biometric information; a controller configured to: receive contextual information from one or more of the plurality of sensors; receive first biometric information from a first sensor of the plurality of sensors; perform a first biometric authentication comprising a generated similarity value between the received first biometric information and first biometric user information stored in the memory, wherein the first biometric authentication uses a first comparison threshold which varies based on the received contextual information; when the first biometric authentication is successful, execute the function according to the successful authentication; when the first biometric authentication is unsuccessful, perform a second biometric authentication using a second biometric information received from a second sensor of the plurality of sensors.
