An electronic device includes a touch screen display, a biometric sensor, an audio interface, a wireless communication circuit, a processor, and a memory. The memory stores instructions causing the processor to receive a selection of a first authentication scheme for a payment in a default scheme, to set the first authentication scheme as the default scheme, to receive a user utterance indicating a payment action task using a second authentication scheme, to transmit data associated with the user utterance to an external server, to receive a response including a state sequence of the electronic device for performing the payment action task and a parameter associated with the second authentication scheme, to perform the payment action task depending on the state sequence in the second authentication scheme, and to provide a user interface for changing the default scheme to the second authentication scheme. |
