2title: I made a small auth server template for Deno Deploy
3description: I've fallen in love with Deno and its Deploy service, but also OpenAuth, so I made a simple template to deploy OpenAuth to Deno Deploy, using Deno KV for storage.

13I'm currently messing around with Deno Deploy to build a tiny little service for myself, and I needed authentication—all apps need auth nowadays, url scanners are out of control.
14
15I didn't really want to have the auth server coupled with the main service, so I just made it into a [separate repository](https://github.com/finxol/auth).
16The advantage here is that it's very minimal, so it runs for free no problem.

18It's just a very basic wrapper around OpenAuth, using Deno KV for storage. It took me an afternoon to put together properly,
19but if you need a little auth server and not bother too much, this might be a good starting point.

21With that, I can now use my own domain to authenticate users, and I only need my url and client id key.

23So go crazy, [follow the instructions](https://github.com/finxol/auth#deploy) in the README, and deploy it to Deno Deploy!
