Remarks

Usually, the shared secret is provided by the provider or service website to the user by means of a QR code. Both sides need to retain this secret key for one-time password generation. The YubiKey takes care of securely storing this secret on behalf of the user when the credential is added. An authenticator app does not need to store this secret anywhere else.
