44.7.7.3 Avoiding Browser Warning Messages
Here are the main reasons your browser displays warnings about the Zyxel Device's HTTPS server
certificate and what you can do to avoid seeing the warnings:
• The issuing certificate authority of the Zyxel Device's HTTPS server certificate is not one of the browser's
trusted certificate authorities. The issuing certificate authority of the Zyxel Device's factory default
certificate is the Zyxel Device itself since the certificate is a self-signed certificate.
• For the browser to trust a self-signed certificate, import the self-signed certificate into your operating
system as a trusted certificate.
• To have the browser trust the certificates issued by a certificate authority, import the certificate
authority's certificate into your operating system as a trusted certificate.
44.7.7.4 Login Screen
After you accept the certificate, the Zyxel Device login screen appears. The lock displayed in the
bottom of the browser status bar denotes a secure connection.
