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.

There are tons of open source projects to complete the self service experience, from sign up systems to self service password resets

I’ve been using https://clerk.com. Not needing to build authentication / the UI / … as well as not worrying about hosting it myself has been nice.

This is the absolutely simplest of authentication (not authorization) schemes I've used that is both easy for people to use and prevents the simplest of spam/robots:

- Be able to store two types of tokens, one that is temporary, and one that is "permanent"

- Users can use their email address to get sent a temporary token (which expires if unused after X minutes)

- Users can click that link to change the temporary token for a "permanent" token they (the frontend) can use for authentication

- Clicking "Logout" invalidates the currently used "permanent" token

Biggest issue is making sure that whatever email provider you use for the "Login Emails" 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.

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'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'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't have been much easier, and the free tier seems more than generous enough to get through the prototype stage.

My main concern is that I don't want to weld too much of my design to any one service provider, so I've got to be careful about taking too much advantage of their feature set and API so that it won't be a pain if they go away or it becomes necessary to migrate to something else.

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].

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

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

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.

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.

Using password auth for now. Will migrate to auth0 if enterprise customers knock on the door and want SAML.

I was thinking Kanidm [1] for authentication and SpciceDB [2] for authorization would be a good combo, but I haven't gotten around to trying it yet.

I use firebase auth with Google, Facebook and email (magic link)

This is live at https://screenrun.app/

Email+password, jwt tokens. Nothing fancy.

Social auth almost always means oauth (2.0). It's good to have this, because you could technically Deploy your own oauth provider.

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.

I plan to try openid but i did not habe the time yet.

If you have a userbase, a local username/password login should be at least an Option...

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't need to maintain TLS certificates.

Django allauth, 10 years later still a no-brainer.

For selfhosting Authentik + Traefik forward auth is a unbeatable combo

Selfhosted https://goauthentik.io/

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

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

We use Keycloak

Google, Apple, and Email using PocketBase.

Phoenix Auth

None or username/pwd

X509 certs. They work nicely in an offline situation.

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

Supabase

I make it a point not to have public user accounts for my stuff because it's such a liability.

For admin, I use HTTP basic auth like the boomer I strive to be.

I used to use Facebook because it's really easy to work with

Appwrite, all in one, and it shockingly just works from install to go focus on building the side projects.

Cheap/ 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 :)

None. Users should handle their own data.

Firebase

Auth0 and FusionAuth

Auth.js!

Supported providers: https://authjs.dev/getting-started/providers/github

It's been really great so far and I can recommend it if you have a JS/TS codebase.

----------------------------

You can test Auth.js (v5 beta.22) in my Next.js 15 boilerplate:

https://achromatic.dev

• Credentials auth

• Google and Microsoft login

• Connected accounts

• Multi-factor authentication (via authenticator app)

• Session management
