Web browser reports that connection to FRITZ!Box is not safe
When you try to open the FRITZ!Box user interface, the web browser displays one of the following messages:
- "Your connection is not private" (Google Chrome)
- “Your connection is not private” (Microsoft Edge)
- "Warning: Potential Security Risk Ahead" (Mozilla Firefox)
- "This connection is not secure" (Mozilla Firefox)
- "This Connection is Not Private" (Apple Safari)
The messages are either displayed in the web browser's address bar, when you enter the password for the user interface, or in the web browser itself. Note the information given in the corresponding section.
1 Web browser shows a non-encrypted connection
If the web browser describes the connection to the FRITZ!Box as "Not secure" in the address bar or displays a lock with a red line through it :
The web browser indicates that connections to websites that are not or are only partially encrypted are not secure because data entered on such websites can be stolen by a third party. You can ignore this message because the FRITZ!Box user interface is opened within your home network and no data is sent over the internet.
2 Firefox reports "This connection is not secure"
If Firefox displays the message "This connection is not secure. Logins entered here could be compromised" when entering the password for the FRITZ!Box user interface:
Firefox warns you about transmitting passwords over an internet connection that is not encrypted because the password could be stolen by a third party. You can ignore this message because the FRITZ!Box user interface is being opened within your home network and your password is not sent over the internet.
3 Web browser warns about unknown security certificate
If the web browser displays a certificate warning instead of the FRITZ!Box user interface:
When establishing an encrypted HTTPS connection, the web browser checks the website's security certificate. Since the FRITZ!Box's individual security certificate is not known to third party organizations that issue such certificates, the web browser indicates that the HTTPS connection to the FRITZ!Box is not secure.
We recommend using MyFRITZ!Net to access the FRITZ!Box via the internet. If you use a certificate from letsencrypt.org, the web browser does not display a certificate warning.
When accessing the FRITZ!Box from the home network or using a different dynamic DNS provider, confirm the web browser's certificate warning. This does not pose a security risk.
