Sometimes, we receive some feedbacks which are related to the security issue of Tenda web interface management via HTTPS. When customers enable Local Management via HTTPS option on Tenda router to stay extra safe, some web browsers still report Not Secure when accessing HTTPS Tenda web interface however. This article will explain why this happens with details.

The error message reported by some web browsers for Tenda https web interface would be like the following picture:

The reason why our browsers recognize tendawifi.com as “insecure” is that tendawifi.com’s Certificate is a self-signed Certificate. Most browsers do not accept this kind of Certificate because tendawifi.com is not an authoritative CA.

However, even if our self-signed Certificate is not trusted, the connection between your browser and the tendawifi.com server is secure.

A Certificate's purpose is only to allow a client verify an unknown server. It has nothing to do with the encrypted connection. The data transmitted between the browser (client) and tendawifi.com (server) remains safe and encrypted. No one else could decrypt these data except the client and the server.
