PlexAuth, PHP based Plex authentication for your domain.
https://github.com/hjone72/PlexAuth
The idea was to secure my domain using familiar username and passwords for my users. I wanted to remove the need for users to have to sign in at each different website (comics, plex, requests, etc) but still wanted them to all be secure. I hate the idea of shared passwords so I came up with this project.
Using Nginx's Auth_Request module I've now been able to secure all the services using users Plex credentials.
Let me know what you guys think.
