By default, the device allows an administrator to log in to the FW web UI using HTTPS.
The following browsers are recommended for logging in to the web UI of the device:
By default, the FW supports TLS1.2. You can run the web-manager security version { { tlsv1 | tlsv1.1 | tlsv1.2 } * | all } command to change the supported protocols. If the browser uses SSL of outdated insecure versions, the login page cannot be accessed. In addition, using a browser of a much earlier version may also cause the login page to be inaccessible. In this case, upgrade the browser.
Firefox: Choose and ensure that JavaScript is enabled.
JavaScript is enabled by default on version 23.0 and later. Therefore, the preceding configuration option is unavailable for them.

If the address is http://192.168.0.1, the device automatically uses the more secure HTTPS to access the web UI.
The browser prompts you with a message, saying that the certificate is insecure. Select to continue browsing. For security, you are advised to configure the specified certificate after logging in to the device. For details, refer to CLI: Example for Logging In to the Web UI Using HTTPS (Specified Certificate).
The administrator account is a string of 1 to 64 case-sensitive characters, and cannot contain such characters as the vertical bar (|), backslash (\), slashes (/), colon (:), asterisk (*), ampersand (&), question mark (?), apostrophe, equal sign (=), number sign (#), straight quotation mark ("), less than sign (<), greater than sign (>), and at sign (@). It is recommended to be different from command keywords.
Use HTTPS to log in to the web UI for management and configuration. You can also create more administrators. For details, refer to Administrator.
