17The following figure shows the use of **userAuthIcon** for fingerprint authentication. When a user taps the fingerprint authentication icon (shown in the left part of the figure) integrated into the application, the system starts the user authentication component (shown in the right part of the figure) to complete identity authentication. The embedded icons eliminate the need for initiating user identity authentication requests by using APIs, making the identity authentication process simpler.
