Grant VS dex

I am implementing OAuth with Grant. It looks pretty fantastic with 200+ providers and completely manages full OAuth with a single config file. The problem is I am unable to work it with Next JS. The library works perfectly when I create a test project with express and express-session with these libraries it works perfectly from login to logout everything. In Next JS, I am using iron-session for session management.

Thanks for taking a look! I use the https://www.npmjs.com/package/grant for OAuth (to spare people having to remember yet another password) and I believe it uses cookies to prevent OAuth replay attacks. Thanks for highlighting this. I'll work on a better error message if cookies are not enabled.

Use a proxy like grant or delegating Idp like dex

An alternative to passport is https://github.com/simov/grant

Dex: https://dexidp.io

Recently I looked into having a relatively simple SSO setup for my homelab. My main objective is that I could easily login with Google or GitHub auth. At my previous job I used both JetBrains Hub [1] and Keycloak but I found both of them a bit of a PITA to setup.

JetBrains Hub was really, really easy to get going. As was my previous experience with them. The only thing that annoyed me was the lack of a latest tag on their Docker registry. Don't get me wrong, pinned versions are great, but for my personal use I mostly just want to update all my Docker containers in one go.

On the other hand I found Keycloak very cumbersome to get going. It was pretty easy in dev mode, but I stumbled to get it going in production. AFAIK it had something to do with the wildcard Let's Encrypt cert that I tried to use. But after a couple of hours, I just gave up.

I finally went with Dex [2]. I had previously put it off because of the lack of documentation, but in the end it was extremely easy to setup. It just required some basic YAML, a SQLite database and a (sub)domain. I combined Dex with the excellent OAuth2 Proxy and a custom Nginx (Proxy Manager) template for an easy two line SSO configuration on all of my internal services.

In addition to this setup, I also added Cloudflare Access and WAF outside of my home to add some security. I only want to add some CrowdSec to get a little more insights.

Another great option is to use https://github.com/dexidp/dex in an authentication setup. In your app, you federate the authentication to dex using OAuth2. Dex then has a pluggable architecture with built-in connectors for many established identity providers using a variety of protocols: Among others OAuth2, SAML 2 but also GitHub, Google, Gitea and so forth.

dex is well-known: https://github.com/dexidp/dex

We used keycloak for openid identity provider as well. It is fine to setup keycloak once. But it is painful share the setup with other engineers.

For local development, we end up using dex (https://dexidp.io). When we need support group/role, we use dex and glauth(https://glauth.github.io). Both dex and glauth can be configured with yaml files. We just created a few yaml files and a docker compose file, every engineer can be brought up the whole environment in a few seconds.

Also https://www.authelia.com and https://github.com/goauthentik/authentik look pretty promising, if you need more advanced features from them.

I added it as an available option (flake) in Dex: https://github.com/dexidp/dex
