private video stream

So, I may have bit off more than I can chew with this one, and I need some pointers. I'm working on a streaming/recording setup for a client. I thought that OBS Studio would do the job, but it appears that OBS cannot be used independently to host a video stream. Can anybody explain how I can achieve this? I need to self-host a video stream that the client can connect to from any device (including Windows, Mac, Linux, Android, and iOS) using something along the lines of VLC. The stream must be private and accessible to only those with a key/password. I do not have access to a static IP address. I suspect there must be a way to make this happen -it's just pushing data over a network connection, the question is what software do I need, and potentially also, how do I use it?

obs may still be useful to you, it can build the video stream, allowing you control over what actually is displayed. Then you need an rtsp or rtmp stream to get it from obs to the receivers. A quick search found me this rtsp plugin for obs: https://obsproject.com/forum/resources/obs-rtspserver.1037/

otherwise, you can find the streaming software of choice, then use the obs virtual camera to send the feed to that, if you need anything more complicated than just streaming in the camera.

I'll look into it, thanks! Any recommendations for client/viewer apps? Particularly for iOS... Client has an iPhone but I haven't had an iOS device in a decade.
