Google Smart Lock for Password on Android

By integrating Smart Lock for Passwords into your Android app. Integrating Smart Lock for Passwords into your Android app in a simple and automatic way. You can automatically sign users in to your app using the credentials they have saved. Users can save both username-password credentials and federated identity provider credentials. Integrate Smart Lock for Passwords into your app by using the Credentials API to retrieve saved credentials on sign-in. Use successfully retrieved credentials to sign the user in, or use the Credentials API to rapidly on-board new users by partially completing your app's sign in or sign up form. Prompt users after sign-in or sign-up to store their credentials for future automatic authentication.

		}
	}

     */
    fun smartLockStoreCredentials(username: String, password: String) {}

     */
    fun smartLockStoreCredentials(username: String, password: String) {}
    
    
    /* SmartLockInterface */
    fun onCredentialsResult(username: String, password: String) //you can use auto login from credential retrieved
