Very impressive, and at the same time very scary because who knows what security issues are hidden beneath the surface. Not even Claude knows! There is very reliable tooling like https://github.com/ory/hydra readily available that has gone through years of iteration and pentests. There are also lots of libraries - even for NodeJS - that have gone through certification. In my view this is an antipattern of AI usage and „roll your own crypto“ reborn.
In Cloudlflare builds OAuth with Claude and publishes all the prompts
Hey Sytten, I work in the community team for Ory. OSS is actually very important for us and definitely not second class. (see also https://www.ory.sh/docs/open-source/commitment) The assumption that Ory does not offer support contracts for self-hosted Ory is wrong (although we did not in the past, when the team was smaller). We are doing contracts for companies using our software self-hosted: See here and contact us if you are interested! https://www.ory.sh/support/ This way we can assign engineers to your case and work on any issues you encounter or work on any contributions or features required. Ory releases all features for free for everyone to use. What is not free however is our time and work. To merge a PR/add a new feature/etc. a significant amount of time is needed to make sure the code lives up to standards, passes all tests,

any security implications, etc. This depends on the feature of course, but the one you are alluding to is probably one of those. See the Code of Conduct on OSS support as well: https://github.com/ory/hydra/blob/master/CODE_OF_CONDUCT.md I hope that makes it clearer and feel free to reach out to me directly in the Ory Community on github or slack.
In Blueprint for a distributed multi-region IAM with Go and CockroachDB
Congrats on the launch, building a product in this space is incredibly difficult. I took a look at the stack, here are a few observations: - "ISO certified secure auth": What does that mean? I could not find proof of your ISO certification. Can you please share? - 10k M2M tokens for $250/month sounds like a really bad deal if I can just spin up https://github.com/ory/hydra that can easily handle 10k requests per second. - Looks like you're using OAuth2 as the primary "login" and "session management". What compelled you to do this? - It looks like you're using some open source technology under the hood for the OAuth2 flows - which one are you using (out of curiosity)? And finally, what sets you apart? It looks like the same solution for the known problem that big players (such as Okta and Auth0 - publicly traded) have already mastered. Ory

(github.com/ory) for example has it's global network approach where you no longer need datacenter locations and is Open Source. Clerk is targeting React devs. What's your niche? Doing everything from auth to billing is, in my experience, way too much for a small team with little resources. Just getting Auth right is a mammoth task.
In Show HN: Kinde – auth, feature flags and billing (Q3) in one integration
Keto only does authorization, independent of users, devices, bots, applications, ... Basically you store your ACLs there and then ask "is _subject_ allowed to do _relation_ on _object_". All the variables are whatever you define them to be. Check out https://github.com/ory/kratos, our identity server. Or https://github.com/ory/hydra, our OAuth2 server. All of them together can be assembled to have something like Keycloak.
In Ory Keto, open source authorization server based on Google Zanzibar
The first vulnerability is in the title, OAuth is an Authorization framework (Open Authorization) and is explicitly NOT for authentication. It’s also a delegation protocol (I give you something to do on my behalf). If you want a list of things that can go wrong, look here: https://tools.ietf.org/id/draft-ietf-oauth-security-topics-1... Generally you probably do not need OAuth2: https://www.ory.sh/hydra/docs/concepts/before-oauth2/ But if you do don’t roll your own but use proven open source like https://github.com/ory/hydra
In OAuth 2.0 Authentication Vulnerabilities
Personally I think of Authelia and Keratin as really good projects in the don't-build-auth-into-your-apps-ever-again space. If auth isn't already built into your app gateway/mesh/proxy, then these services might be something worth dropping alongside. A few more projects in this space: - Keycloak (you won't get fired for picking this)[0] - CloudFoundry's UAA[1] - Gluu [2] - ORY (Hydra + friends)[3] - Keratin [4] - OpenUnison [5] - Dex[6] - Netlify's GoTrue[7] All of these solutions are a bit different but here are some of the axes: - Whether or not they function as an OAuth provider - Whether they're centered around application-user-login via mechanisms like email/password, application auth, or SSO - Whether or not they serve as a proxy to another down-the-line OAuth provider (Dex, GoTrue) - GUI availability - F/OSS-ness (basically all of

In Authelia is an open-source authentication/authorization server with 2FA/SSO
Keycloak and Authelia try to solve everything at once. So you get user management, but you also need to use their template and plugin system (so Java for Keycloak) and you can't use a different OAuth2 provider because well - you use Keycloak. I really love the projects and they have their use cases - with Ory however, you simply pick what you need: - Login, registration, mfa, user management, password change, account recovery, ... - Ory Kratos: http://github.com/ory/kratos - Permission management, roles, who is allowed to do what - Ory Keto: http://github.com/ory/keto - OAuth2, OpenID Connect Provider that you "connect" to your user management (e.g. Ory Kratos) - Ory Hydra: http://github.com/ory/hydra - A "middleware" which checks if requests are authenticated (who is the caller?) and authorized (is the caller allowed to do that) - Ory Oa

thkeeper: http://github.com/ory/oathkeeper It's a bit like lego where the other projects are more like the full car you buy. The car might use little fuel but it's slow and you can't change that. The lego parts you can combine any way you want. Plus, Ory is written in Go and we aim for supporting planet-scale distributed data stores to support global deployments with low latency, and other cool stuff! The last point, we are actually building out a cloud service (think CockroachCloud without the licensing issues), which means that you don't buy a support contract from IBM but instead get everything with a few clicks! Kinda like Auth0, Okta, or Firebase - but with everything open source (maybe like sentry.io?)
