The Google Authenticator app only supports manual configuration.
To initiate configuration in the Google Authenticator app, the user creates an account for two-factor authentication using the app. After account creation, the user manually enters the secret key received from the resource owner. (For details on the secret key, see Generating a Secret Key for the Oracle Mobile Authenticator.) Additionally, ensure that TOTP is enabled at the bottom of the Google Authenticator screen. Google Authenticator generates the OTP code in an offline, disconnected mode; it does not interact with Access Manager.
