Oauth and enterprise auth has to be the worst thing ever made, it might be the most confusing and frustrating part of dealing with the cloud. Even the AI tools took a year to just get basic Oauth working on headless systems without assuming you could open a browser. If they're going to go down the auth rabbit hole with RBAC/IAM/Workload identities?/service accounts and all the trash the big cloud providers have, I just hope to god they leave in the simple shit for personal use. I just want a damn API key, I keep it a secret and revoke if necessary and don't need 10000 layers of auth bullshit tangled up in every layer of every platform.

What I don't understand is why OAuth is rarely talked about in a privacy context, however your OAuth provider knows all the sites you log into and when.

It's a privacy nightmare.

Your OAuth provider can also vouch for anyone who pretends to be you, if they so desire. They can give access to anyone, including themselves.

True they'd know which sites you've signed up to, but not the login times, unless the service emails you every time you log in.

OAuth2 is complex and often not the right tool. I wrote Ory Hydra and also a blog post when OAuth2 is/is not a good idea: https://www.ory.com/blog/oauth2-openid-connect-do-you-need-u...

For API Keys we just launched Ory Talos (https://github.com/ory/talos) - a perfect alternative for when OAuth2 is too much for the use case.

There are use cases and security concerns that legitimize using OAuth2 - with specs like DPoP you can make these flows more secure. In my view the use cases presented here is a good one for OAuth2, but it certainly doesn’t make sense everywhere - complexity makes system harder to secure.

Don't get me wrong but data shows that you will likely fail to keep that api key a as secret and you will also fail to revoke when it becomes necessary. You will definately not going to rotate it frequently as you should.

Good thing about the OAuth2/OIDC is these things will not put the trust on the bearer of the api key, but on actual identity that needs to have the access.

> Good thing about the OAuth2/OIDC is these things will not put the trust on the bearer of the api key, but on actual identity that needs to have the access.

And... you do not see the myriad of problems with that? What about the OIDC provider going rogue or getting compromised? How do you ensure whatever you use to authenticate with your OIDC isn't compromised? Many identity providers and identity bearers have terrible security practices. "Add a backup email in case you lose your 2FA. Nevermind it's the same email we use for password reset."

Again, I trust zaptheimpaler to keep their secret much better than this whole pretend security theater.

Can you share source of this data? I have my doubts about the quality of the data, since OAuth2 is such a complex system with so many footguns.

In the end there is always some long lived secret. What changes is just where and how it is stored, secured and used.

I bet we can generalize to say that data shows that you will likely fail to properly secure any secret (including the ones used in OAuth2).

Not quite. You shift the trust from the key bearer (the most interested party in all of this) to the identity provider.

Then implement that on your app... You are just generating a random key and storing a hash + salt.

Auth is hard only applies to auth for many users. For your own auth this is dead simple and made even simpler if you use a half decent framework...

If you are really worried about the implementation being insecure throw one of the many moderately frontier models at it, they are really not bad at finding issues in an auth system that simple.

I am tempted to agree with you because I could never quite wrap up my head around it, but I never had to implement OAuth beyond a brief skim through the doc for my own understanding. I always thought this complexity was there for some good reason (security?).

OAuth is designed so that an end-user never needs to see an API key (OAuth refresh/access token) or even know what one is. When it is implemented to the spec, that happens well.

I think that most of the "just give me an API key" comments are from a <1% of end-users (developers) that know what an API key is, and are facing a broken OAuth implementation.

far from it! it was just designed by comitee who both future proofed it and made sure it worked on low powered devices from 1971.

i make a point to implement oauth from scratch, because using the overly complex libraries expose you to bugs such as attacker sending a token which the metadata just says "no encryption or signature. trust me bro", which is actually part of the spec if you combine some options.

while in the real world, if google or apple sends you a token that is not always the same signature cypher (one of a dozen by the spec) you are better of threating as malicious, because it pretty much is. a manual implementation of a token consumer is about 20 lines... including downloading the provider keys and checking it (which most startups never do! allowing anyone to just sign a token as anyone)

Oauth is fine if you need the complexity, that is a lot of apps sharing common identity information. Then it certainly is superior to the classic workflow.

I agree that it is too complex though and app to app auth is certainly not a focus. I often still use static common secrets and see no problem with that.

I hate for apps needing to save passwords themselves, even if we have good tools today and the standard bcrypt call is reasonably safe. But then you need to reimplement password reset flows and all that ugly shit. Having that centralised is often

I would recommend self-hosting an OIDC service for that matter. The control you get also allows you to easily comply with some laws like GDPR and cousins, because you need to just purge a user in a single system.

Otherwise I thoroughly feel the frustration with IAM and the big providers. Ain't nobody got time for that and it is never a good and efficient solution.

> I would recommend self-hosting an OIDC service for that matter.

Seconded. It is fairly easy to set up, and so much easier than the cloud IAM things.

The only catch is, make sure you have some backup access to your OIDC provider in case it goes down. E.g. don’t host it on a server with SSH only accessible through VPN that is authorised using your OIDC provider, etc.

I run Codex in multiple disposable sandboxes and OAuth is such a fucking pain. I vibe-coded a project which just stores/allocates/shuffles codex auth.json files around. I have a codex instance that I manually authenticate multiple times with browser OAuth, then copy that auth.json in a store from where it's distributed to the sandboxes. And sandbox codex sometimes refreshes the authorization, so when that happens I need to send that auth.json back to the central store. Madness.

One good thing GitHub Copilot has it that you can just give it a GH_TOKEN that is valid for 6 months and stop this browser login nonsense.

Cloudflare really likes to publish new projects, but improving them in the future is not really their style. Some examples:

- They launched Cloudflare Web Analytics in 2020, but it still does not support basic things such as UTM parameters or custom events

- With wrangler (their CLI), you still cannot undeploy a Cloudflare Page

Valid points (although Keycloak was Redhat not IBM and then donated by them to CNCF), but should "security SLAs for CVEs" be listed as a premium feature?

Looked at the case study, uses Cockroach which is now commercial, so potentially with the dual costs of Ory and Cockroach licenses, unless you need massive scale, would be too expensive for small/medium and also startups? Unless your sole focus is on enterprises?

I cannot agree more. Cloudflare has some services that are really cheap (r2) to lure you into their worker "ecosystem", which is just serverless. Once you are vendor locked into their absolute garbage custom JavaScript runtime, you are pretty much forced to use their distributed database Cloudflare KV if you want good performance. Cloudflare KV is so extremely ridiculously absurdly expensive that make predatory pricing of vercel that HN likes to complain about feel like child play.

Not sure whats the play here, there is no world where this can turn out good. Cloudflare is more or less infrastructure provider, this idea of some user delegating permissions to their account to some third party client for infrastructure is ripe for abuses. If companies like AWS are not doing it then its for a good reason.

AWS do exactly this. An example use-case is IAM can grant permission to update a Lambda to a Github action running in a given repository.
reply

Personally I dont like the way they do it, its hard to understand, if anything its convoluted.

In case of AWS, you add Github as an IDP (OIDC provider) and associate a role to it.

Github is now authenticating into AWS, scoped to the github repository where its configured and the AWS role it can assume

Its not really a typical OAuth2 or OIDC flow. And yes its better than storing the keys.

Github is not the OAuth client here.

Do you understand what OAuth is? It’s like an API key but less likely to be abused. This is a good thing. It helps security in many ways and makes security flows more safe than carrying around a token.
reply
sandeepkd 5 hours ago
I really feel sad about the state of security and its bit hard to unwrap in one paragraph which makes it more challenging. Let me try to be bit more verbose

Cloudflare API Keys - You create them and then use those keys directly against cloudflare API's to manage services/infrastructure in your account. How you create the keys is may be a different kind of challenge.

OAuth flow in discussion here - You are using a third party service (which registers themselves as a the client application with cloudflare), this service is going to prompt you for OAuth flow and redirect to Cloudflare, not (only) to authenticate you but it will get a access token on your behalf (your cloudflare account) from Cloudflare. Whatever this THIRD PARTY service uses this token for your behalf is going to incur infrastructure cost for your account.

reply
ok_dad 5 hours ago
Yea and if you need to use that service then an API key does the same thing. People were giving these services the API keys which isn’t great. You can argue that third party services aren’t a good idea, but then why are you using cloudflare? I don’t understand why you think this is a security issue, if you don’t trust a third party service don’t use it. You have to approve the permissions, they don’t just steal them.

Sorry if I was rude earlier but saying OAuth is some security flaw made me think that you didn’t understand what it was about; it’s just a way to grant permissions to a third party you trust. If you do then I’m curious why you think it’s flawed.

OAuth is pretty simple, just read the spec.

Your go to a third party web site. They send you to your OAuth provider, like cloudflare. Cloudflare asks you to login if you’re not logged in, then asks if you want to give that party certain permissions. You say yes or no and then click approve and then you get redirected back to the third party site. They get a secure token and can use that to access the services with permissions you approved. If you don’t trust the third party then don’t approve it.

It is like an API key but you never have to touch it. The third party can encrypt it and store it securely and it never has to be copied and pasted. You can use this on backend services that need to access things too. I recently wrote an OAuth client for MCP servers for something I’m building (not gonna advertise here because that’s rude) and it’s very nice once you read the spec.

reply

OAuth2, to be more precise, is a protocol which can be used both for authentication (verifying the user) and authorization (accessing resources on behalf of that user).

Most people in CIAM (customer identity, individuals owing their account instead of representing a company) only interact with OAuth client for authentication. They do not give access of their google account to some THIRD PARTY COMPANY.

>Earlier this month, we announced self-managed OAuth, making it easier for customers to create and manage their own OAuth clients for delegated access to the Cloudflare API.

They're letting you host an OAuth system to approve/deny access to your own resources, so you can build whatever logic you like, rather than waiting on them to allow you to do X under Y conditions. Essentially "log into CloudFlare" -> CF sees you're using this self-managed OAuth -> redirect to your OAuth -> CF trusts your response, and approves access to your account if you approve access.

I wish Cloudflare provided a paved path for user auth.

Better Auth seems to be the most common recommendation for Typescript applications, but there currently doesn't seem to be an official integration with Workers either from Better Auth or from Cloudflare.

I currently use Supabase to avoid having to set up my own user auth on Workers, but I would much prefer to use D1 etc.

As much as I’d like to love Better Auth, the assumptions they make sometimes are so damn annoying. Having to resort to hacks to e.g. support an OIDC provider that doesn’t return user’s email (like Telegram) is a PITA.

I find Lucia Auth’s approach more useful in the long run – you have some boilerplate living on your codebase but you own it completely and it doesn’t try to make decisions for you: https://lucia-auth.com/

That said, why don’t you use Better Auth with Drizzle and the D1 adapter?

My pet peeve is the standard OpenID connect implementation of OAuth for SPAs - which will probably use the PKCE code flow. It is probably for historic reasons and old browser compat, but exposing access token and revocation token to javascript is IMHO just madness. In modern security flows you would save those tokens into cookies that are HttpOnly and SameSite=strict and prevent a myriad of JS based attack vectors.
