WebUI authentication

Solar2MQTT supports optional HTTP basic authentication for the Web UI.

Enable it

1. Open Wi-Fi
2. Expand Advanced Network Settings
3. Fill Username
4. Fill Password
5. Save settings

Disable it

1. Open Wi-Fi
2. Expand Advanced Network Settings
3. Clear the username
4. Save settings

Current behavior

• Authentication is skipped in AP mode so initial setup remains reachable.
• Once the device is on your normal Wi-Fi, the configured username and password protect the Web UI.

Security note

This is local HTTP basic authentication only. Do not expose the Web UI directly to the internet.

If you need remote access, use:

• VPN
• reverse proxy with proper authentication and TLS
• other network-level protection
