Ask HN: What type of Auth are you using on your side projects?

Keycloak or auth0. The app should support oauth2, if it does not it gets traefik-forward-auth (or whatever it’s called) to enforce mfa then you are in.<p>There are tons of open source projects to complete the self service experience, from sign up systems to self service password resets

This is the absolutely simplest of authentication (not authorization) schemes I&#x27;ve used that is both easy for people to use and prevents the simplest of spam&#x2F;robots:<p>- Be able to store two types of tokens, one that is temporary, and one that is &quot;permanent&quot;<p>- Users can use their email address to get sent a temporary token (which expires if unused after X minutes)<p>- Users can click that link to change the temporary token for a &quot;permanent&quot; token they (the frontend) can use for authentication<p>- Clicking &quot;Logout&quot; invalidates the currently used &quot;permanent&quot; token<p>Biggest issue is making sure that whatever email provider you use for the &quot;Login Emails&quot; consistently sends emails quickly, as there is nothing worse but sitting for 2-3 minutes waiting for a login email because the provider batches sends or something.<p>This would specifically be for side projects. If it grows beyond that, you really should implement something with proper rotation and more, but there are tons of resources about that out there.

I develop an internet forum [0] that uses express-session with a Redis datastore for standard username and password website login. Separately, it also has a JSON API that uses OAuth 2 auth code flow with PKCE [1].<p>[0] <a href="https:&#x2F;&#x2F;github.com&#x2F;ferg1e&#x2F;comment-castles">https:&#x2F;&#x2F;github.com&#x2F;ferg1e&#x2F;comment-castles</a><p>[1] <a href="https:&#x2F;&#x2F;www.commentcastles.org&#x2F;api#api-user-authentication" rel="nofollow">https:&#x2F;&#x2F;www.commentcastles.org&#x2F;api#api-user-authentication</a>

I’ve been using <a href="https:&#x2F;&#x2F;clerk.com" rel="nofollow">https:&#x2F;&#x2F;clerk.com</a>. Not needing to build authentication &#x2F; the UI &#x2F; … as well as not worrying about hosting it myself has been nice.

I&#x27;ve been in big tech and out of touch with the real world for a while, and I started a project only a couple of weeks ago to get a feel for what the cool kids are doing in web dev in 2024. So I can&#x27;t claim any deep authority or experience with a lot of different approaches. But I picked Clerk because it was in a tutorial, and so far so good. It couldn&#x27;t have been much easier, and the free tier seems more than generous enough to get through the prototype stage.<p>My main concern is that I don&#x27;t want to weld too much of my design to any one service provider, so I&#x27;ve got to be careful about taking too much advantage of their feature set and API so that it won&#x27;t be a pain if they go away or it becomes necessary to migrate to something else.

A lot of my side projects are only visible over a VPN. I have no auth for them as it is not needed.

Amazon Cognito. If I ever scale past a handful of users and it starts costing money I&#x27;ll revisit but for a side project? Auth is the least interesting part and I just want it to work securely with no fuss.

None, because my projects never make it as far as launching.

In my latest side project I am allowing people to start using the tool without signing up. You can see it working on sandbox.wasitsent.com.<p>I am using Django’s user system. When a user comes and wants to use the app, I create a Django user and mark it as auto-created. Later, when they decide to sign up, I fill the details and I mark it as auto-created.<p>Using password auth for now. Will migrate to auth0 if enterprise customers knock on the door and want SAML.

I first install and configured Authentik with totp then found a million things I can integrate it into because it basically supports everything.

I use Traefik with OpenID Connect for everything, and Google as IdP. It&#x27;s few enough people that I simply add them manually to traefik-forward-auth&#x27;s settings in Docker Compose.<p><a href="https:&#x2F;&#x2F;github.com&#x2F;thomseddon&#x2F;traefik-forward-auth">https:&#x2F;&#x2F;github.com&#x2F;thomseddon&#x2F;traefik-forward-auth</a>

Appwrite, all in one, and it shockingly just works from install to go focus on building the side projects.<p>Cheap&#x2F; free to self host. I have tried a bunch of the other ones and they all had things I liked but Appwrite gave me nothing to complain about other than getting on with building :)

Django allauth, 10 years later still a no-brainer.<p>For selfhosting Authentik + Traefik forward auth is a unbeatable combo

I delegate to Puter for <a href="https:&#x2F;&#x2F;hackyournews.com" rel="nofollow">https:&#x2F;&#x2F;hackyournews.com</a><p>HN post: <a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=41738273">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=41738273</a>

Email+password, jwt tokens. Nothing fancy.

I use firebase auth with Google, Facebook and email (magic link)<p>This is live at <a href="https:&#x2F;&#x2F;screenrun.app&#x2F;" rel="nofollow">https:&#x2F;&#x2F;screenrun.app&#x2F;</a>

I was thinking Kanidm [1] for authentication and SpciceDB [2] for authorization would be a good combo, but I haven&#x27;t gotten around to trying it yet.<p>[1]: <a href="https:&#x2F;&#x2F;kanidm.com&#x2F;" rel="nofollow">https:&#x2F;&#x2F;kanidm.com&#x2F;</a><p>[2]: <a href="https:&#x2F;&#x2F;authzed.com&#x2F;docs&#x2F;spicedb&#x2F;getting-started&#x2F;discovering-spicedb">https:&#x2F;&#x2F;authzed.com&#x2F;docs&#x2F;spicedb&#x2F;getting-started&#x2F;discovering...</a>

Social auth almost always means oauth (2.0). It&#x27;s good to have this, because you could technically Deploy your own oauth provider.<p>However, for my smaller personal side projects I rely on a simple JWT auth based on JWT, QR-codes and https-only AS secure AS possible cookies.<p>I plan to try openid but i did not habe the time yet.<p>If you have a userbase, a local username&#x2F;password login should be at least an Option...

Selfhosted <a href="https:&#x2F;&#x2F;goauthentik.io&#x2F;" rel="nofollow">https:&#x2F;&#x2F;goauthentik.io&#x2F;</a>

For admin panels, I use SSH port forwarding, as no additional configuration is needed for that. For users, I use email invite codes that contain the hash of the server’s public key and are pasted into a stand-alone client. That way, I don&#x27;t need to maintain TLS certificates.

We use Keycloak

Keycloak OIDC. Cannot go wrong doing this. Enterprise tested, easy to custom style, well documented hosting story, and no lock-in.

Supabase has very easy to setup auth while scaling beyond auth. You can use it standalone without issue.

Phoenix Auth

None or username&#x2F;pwd

I used to use Facebook because it&#x27;s really easy to work with

Auth0 and FusionAuth

X509 certs. They work nicely in an offline situation.

i use lucia in svelte.<p><a href="https:&#x2F;&#x2F;lucia-auth.com&#x2F;" rel="nofollow">https:&#x2F;&#x2F;lucia-auth.com&#x2F;</a>

Google, Apple, and Email using PocketBase.

Supabase

I make it a point not to have public user accounts for my stuff because it&#x27;s such a liability.<p>For admin, I use HTTP basic auth like the boomer I strive to be.

None. Users should handle their own data.

Firebase

no auth at all
