i'm currently running HiFi Berry OS on a Raspberry Pi 3B+ with a HiFiBerry DAC+. I'm planning to place this device in a Public WiFi and therefore I would like to protect the HiFiBerry Web-Interface with a password. So no one without the password can change any settings like Volume or Source. I already disabled any Streaming Services like Spotify Connect, AirPlay, Roon, etc. This device will be mainly used for playing WebRadio.
Probably I was searching the wrong way but up to now there wasn't any post regarding this.
Thanks for your Help
