+Following the instructions you should configure your Authenticator app. In this case we show the process with the [Microsoft Authenticator](https://play.google.com/store/apps/details?id=com.azure.authenticator&hl=es&gl=US) app. But you can use any other app that supports the TOTP protocol such as [Google Authenticator](https://play.google.com/store/apps/details?id=com.google.android.apps.authenticator2&hl=es&gl=US) or [Authy](https://play.google.com/store/apps/details?id=com.authy.authy&hl=es&gl=US).
