 It is **highly recommended** to protect obs-websocket with a password against unauthorized control. To do this, open the "Websocket server settings" dialog under OBS' "Tools" menu. In the settings dialogs, you can enable or disable authentication and set a password for it.
 
+### Connecting over a TLS/secure connection (or remotely)
+
+**Before doing this, secure the WebSockets server first by enabling authentication with a strong password!**
+
+If you want to expose the WebSockets server of obs-websocket over a secure TLS connection (or to connect remotely), the easiest approach is to use a localhost tunneling service like [ngrok](https://ngrok.com/) or [pagekite](https://pagekite.net/). 
+
+**Please bear in mind that doing this will expose your OBS instance to the open Internet and the security risks it implies. You've been warned!**
+
+#### ngrok
+
+[Install the ngrok CLI tool](https://ngrok.com/download), then start ngrok bound to port 4444 like this:
+
+```bash
+ngrok http 4444
+```
+
+The ngrok command will output something like this:
+
+```

+Tunnel Status                 online
+Version                       2.0/2.0
+Web Interface                 http://127.0.0.1:4040
+Forwarding                    http://TUNNEL_ID.ngrok.io -> localhost:4444
+Forwarding                    https://TUNNEL_ID.ngrok.io -> localhost:4444
+```
+
+Where `TUNNEL_ID` is, as the name implies, the unique name of your ngrok tunnel. You'll get a new one every time you start ngrok.
+
+Then, use `wss://TUNNEL_ID.ngrok.io` to connect to obs-websocket over TLS.
+
+See the [ngrok documentation](https://ngrok.com/docs) for more tunneling options and settings. 
+
+#### PageKite
+
+[Install the PageKite CLI tool](http://pagekite.net/downloads), then start PageKite bound to port 4444 like this (replace NAME with one of your choosing):
+
+```bash
+$ python pagekite.py 4444 NAME.pagekite.me
+```
+
+Then, use `wss://NAME.pagekite.me` to connect to obs-websocket over TLS.
+
 ### Possible use cases
 
 - Remote control OBS from a phone or tablet on the same local network
