However, if the mobile device has been stolen or lost and it is no longer possible to uninstall the FRITZ!Apps, proceed as described in this guide to revoke the apps' rights to access your FRITZ!Box.

In this case we also recommend changing the network key of the FRITZ!Box and deleting VPN connections configured for the mobile device in the FRITZ!Box.
