🛡️ uSentry - Identity & Access Management (github.com)

uSentry is a lightweight, self-hosted Identity and Access Management (IAM) and Single Sign-On (SSO) solution designed for homelab and small-scale environments.

⚡ A single PHP file. < 400 lines of code. No database. No background processes. No cloud. Just works. ⚡

Most IAM and SSO solutions require databases, certificates and background services baked into a dozen containers. This is all fine but also also overkill for homelabs and impossible for low-power ARM devices. uSentry is different, it isn't pretty but it sucks less for a lot of use cases.

Enjoy!

I have been constantly asking myself why there isn't something like this, and just wondering if maybe I was missing something about the seeming immense complexity of doing this on a small scale.

Now there is something like this.

I don't love PHP, but I also don't love having dozens of separate passwords, keys, certificates and other nonsense to keep track of like I'm doing now. I don't mind using PHP to get around that if I can.

Well, it isn’t pretty, but gets the job done.

The thing with PHP in this case is that I was already serving a ton of simple websites / small apps like freshrss that use PHP and by making this tool in PHP it means I don’t need yet another process running and wasting resources, can just re-use the existing php-fpm for this.

For what’s worth PHP is better than it looks, and my implementation is very crude, but also small and auditable and contained to a single file. :)
