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 (for example the Google Authenticator app). In the home network, you can also push a button on the FRITZ!Box to confirm that you want to configure these functions.
