Extra confirmation to configure certain functions
The first time a sensitive function is changed or executed, you will be asked once for additional confirmation. The confirmation is then valid for one hour, so you do not have to reconfirm permission to make further changes during this time. If you log into the user interface again within this hour or open the user interface in a new browser window, you will be asked again for confirmation when executing a sensitive function.
When accessing it from the internet and the home network, you can enter a confirmation code from an authenticator app. In the home network, you can also push a button on the FRITZ!Box or use a telephone connected to the FRITZ!Box to confirm that the procedure may be executed.
Note:All instructions on configuration and settings given in this guide refer to the latest FRITZ!OS for the FRITZ!Box.
1 Confirming execution by button
- Briefly push any button on your FRITZ!Box when the user interface asks you to do so. The LEDs on the FRITZ!Box flash once to confirm.
- Click "OK" in the "Procedure confirmed" window in the user interface to complete the procedure.
2 Confirming execution with a telephone
IP telephones, for example FRITZ!App Fon, cannot send key commands to the FRITZ!Box. Therefore, you cannot use IP telephones to confirm execution:
- Enter the code displayed in the message in the user interface on the telephone and press the call key (pick up the handset).
- Hang up again after about 3 seconds.
- Click "OK" in the "Procedure confirmed" window in the user interface to complete the procedure.
3 Using an authenticator app to confirm that procedure may be executed
Installing an authenticator app

- Click "FRITZ!Box Users" in the "System" menu.
- Click the (Edit) button for the user who should be allowed to change security-relevant settings over the internet.
- In the section "Confirmation by App (One-time Password)", click "New Setup" and on the FRITZ!Box, confirm that the procedure may be executed, if you are asked to do so.
- Enter a name for the mobile device.
- Open the authenticator app and set up a new account.
- Point the camera on the mobile device at the QR code displayed by the FRITZ!Box until it is recognized.
- Click "Next".
