Even better and easier: MyFRITZ! for browser and app
Following the fritz.box user interface the window to the FRITZ!Box with FRITZ!OS 6.80 the user interfaces of the MyFRITZ! service (myfritz.net) and FRITZ!NAS now also appear in a responsive design and adjust to any display size. Using the MyFRITZ!App 2 (for Android) users have convenient access to saved data, their call list or voice messages - at home and from anywhere else. Users will receive real time notifications via the app about missed calls or new voice messages. With a single swipe you can establish a secure connection to your home network and access your FRITZ!Box and connected devices from on the go. Even Smart Home devices can be operated and switched directly via app or widget.
On the safe side: strong passwords and settings requiring confirmation
The configuration of new IP phones and call diversions as well as the saving of backup files is even safer now as a new function implements an additional confirmation that can only be verified where the FRITZ!Box is located (two-factor authentication). Attempts to log in with wrong user data are recorded as an event. On top of this, FRITZ!OS 6.80 makes sure that users assign a password with at least 8 digits when configuring an IP telephone or an IP intercom system via the FRITZ!Box. Numerous other FRITZ!OS 6.80 upgrades provide the FRITZ!Box with the latest security standards. With every large update AVM always advises to install the latest version of FRITZ!OS for optimum security and best network synchronization.
Approve access from the Internet for online games, gaming consoles or IP devices
Devices connected to the FRITZ!Box are safe from unauthorized access from the Internet. However, certain applications such as online games or devices like IP cameras or gaming consoles sometimes need to be accessible for others over the Internet. FRITZ!Box users can enable such connections through port sharing. Now it's also possible to allow certain devices to control port sharing automatically. With FRITZ!OS 6.80 all shared ports (IPv4, IPv6, MyFRITZ! or autonomous) can be viewed and configured at once. Users can find an overview of all shared ports with their connected home network devices in the menu at "Internet > Permit Access". Settings for parental controls can also be used with pure IPv6 devices with the new FRITZ!OS 6.80. ___________________________________________________________
