The convenience is real, but the actual move is bigger: your signup can now start inside ChatGPT and Codex, where a growing share of builders already live. Here's what it does, what partners get, and whether you should add it. ## Key takeaways - OpenAI has started rolling out "Sign in with ChatGPT" in beta — a Log-in-with button, the same pattern as Sign in with Google or Apple, with ChatGPT as the identity provider. The first partners are Airtable, GitLab, HubSpot, Notion, Supabase, and Vercel; Supabase and Vercel have posted their own how-to on turning it on. - What a partner receives is thin by design: your name, email address, and profile picture when available. Any further access a plugin or connector requests is a separate consent screen the user reviews and approves on its own — the login itself is not a data grab. - The convenience story (one fewer password) is the small story. The real one: it works in two directions. A user can sign in to your product with their ChatGPT account, and a user can add your plugin/connector inside ChatGPT and Codex and link an account in the same motion. That second direction is distribution — your signup can now originate on OpenAI's surface, in front of the builders already working there. - The founder read: if the ChatGPT-native builder is your user, this is a low-friction signup and a foothold inside the agent surface, and it's worth wiring behind your existing auth. If they're not, it's another identity dependency and a beta button — wait. Treat it as one more federated provider next to Google/Apple/GitHub, never as your only front door. ## At a glance | Your product | What "Sign in with ChatGPT" gets you | The move | | --- | --- | --- | | Dev tool / API / builder product (ChatGPT-native users) | Low-friction signup PLUS discovery and account-linking from inside ChatGPT and Codex — real distribution | Add it now, behind your existing auth, as one federated option; instrument how many signups actually originate there | | Prosumer / SaaS with mixed audience | Marginal signup convenience; thin profile data; a beta dependency to maintain | Add it as one button beside Google/Apple/GitHub — never the only path; revisit weight at GA | | Regulated / enterprise / identity-sensitive | A new external identity broker in your trust chain, still in beta | Wait for GA and a data-processing/security review; keep your own IdP authoritative | | Anyone | Name, email, profile picture on login; any further plugin access is a separate user-approved consent | Keep the identity step and the capability grant separate; treat the login as authentication, not authorization | ## By the numbers - **6** — first-wave partners live in the beta — Airtable, GitLab, HubSpot, Notion, Supabase, Vercel - **name · email · picture** — the entire profile a partner receives at login — anything more is a separate consent screen - **2 directions** — sign in to a partner with ChatGPT, and add a partner's plugin inside ChatGPT/Codex — the second is the distribution lever - **beta** — the current status — a reason to add it as one option, not to rebuild your auth around it **Short version:** OpenAI has started rolling out **"Sign in with ChatGPT"** in beta — a federated login button, ChatGPT as the identity provider, the same shape as Sign in with Google or Apple. The first partners are **Airtable, GitLab, HubSpot, Notion, Supabase, and Vercel**. A partner receives only your **name, email, and profile picture**; anything more a plugin wants is a separate consent screen you approve on its own. The convenience is the small story. The real one is direction: your signup can now **start inside ChatGPT and Codex**, in front of the builders already there. If those are your users, add it — behind your existing auth. If they're not, it's a beta dependency you can wait on. What actually shipped A login button. When a user clicks **Sign in with ChatGPT** on a partner product, they authenticate with their ChatGPT account and can create or link an account in a few steps, then keep working with that service inside ChatGPT or Codex. Two of the launch partners — [Supabase](https://supabase.com/blog/sign-in-with-chatgpt-beta) and [Vercel](https://vercel.com/changelog/sign-in-with-chatgpt-is-now-available-on-vercel) — have already posted their own guides to turning it on, alongside Airtable, GitLab, HubSpot, and Notion. OpenAI's own [release notes](https://help.openai.com/en/articles/6825453-chatgpt-release-notes) frame it as the start of an ecosystem, and Greg Brockman [said as much](https://x.com/gdb/status/2083061510180688298): "supporting an ecosystem with Sign in with ChatGPT." What a partner gets at login is deliberately thin: **your name, email address, and profile picture when available**. It is not a permissions grab. If a plugin or connector then wants to *do* something on your behalf, that access is a **separate review-and-approve step** the user sees on its own — so authentication (who you are) and authorization (what an agent may do) stay two distinct screens. Why this is bigger than one less password The convenience framing undersells it. A login button is a funnel play, and it runs in **two directions**: - **Inbound to your product.** A user signs in to your app with their ChatGPT account — one fewer password, faster signup. - **Outbound onto OpenAI's surface.** A user inside ChatGPT or Codex adds your plugin/connector and links an account **in the same motion** — your product gets discovered and onboarded from *inside* the place a growing share of builders already work. Direction 2 is the one that matters. It makes ChatGPT a place where accounts on *your* product are born. That's exactly why Google and Apple wanted to be login buttons: **whoever owns the identity owns the top of the funnel**, and every partner who integrates makes the broker more central. The agent era is just where that old land-grab now points — a dynamic we walked through in [The OAuth Wall](/posts/2026-03-15-the-oauth-wall.html). Should you add it? Decide by where your users already are — not by the novelty. - **Your buyers are ChatGPT-native builders (dev tools, APIs, agent products).** Add it now, wired behind your existing auth as one more federated option. The prize isn't SSO; it's the distribution foothold inside ChatGPT and Codex. Instrument how many signups actually originate there so you can weight it honestly. - **Mixed prosumer/SaaS audience.** Add it as one button beside Google/Apple/GitHub — never the only path. The profile data is thin and the surface is beta; the cost is one more provider to maintain. - **Regulated, enterprise, or identity-sensitive.** Wait for GA and a proper data-processing and security review. Keep your own identity provider authoritative; a beta external broker in your trust chain is not where to move first. One rule cuts across all three: **keep the identity step and the capability grant separate.** "Sign in with ChatGPT" authenticates a *human*. Granting an agent a scoped, revocable token to act on a resource is a different flow — an MCP authorization or an OAuth delegation — and it's the one that carries real blast radius. We covered the authorization side in [MCP's OAuth authorization](/posts/2026-06-22-mcp-authorization-oauth.html) and [OAuth token exchange for agent delegation](/posts/how-to-wire-oauth-token-exchange-for-agent-delegation.html). If owning your identity layer outright matters more than the funnel, [Better Auth](/posts/tool-highlight-better-auth-own-your-auth.html) is the counter-position. The one move this week If ChatGPT-native builders are your users, add **Sign in with ChatGPT** as a federated option today and measure the origin of the signups it brings — the button is the cheap part; the distribution is the point. If they're not, note it, keep your auth authoritative, and wait for GA. Either way, don't rebuild your login around a beta identity provider — add a provider, don't adopt a dependency. This is one thread in a busy week; the full board — the EU's transparency clock, the model price war, and the [frontier models](/topics/model-selection) breaking out of their own test sandboxes — is in [this week's Founder's Wire](/posts/2026-08-03-founders-wire-sign-in-with-chatgpt-deepseek-flash-eu-clock.html). ## FAQ ### What is "Sign in with ChatGPT"? It's a federated login button — the same pattern as "Sign in with Google" or "Sign in with Apple," but with ChatGPT as the identity provider. OpenAI has begun rolling it out in beta so a person can create or link an account on a partner product using their ChatGPT identity, then keep working with that service inside ChatGPT or Codex. The first wave of partners is Airtable, GitLab, HubSpot, Notion, Supabase, and Vercel. ### What data does a partner get when someone signs in with ChatGPT? The login itself passes a thin profile: the user's name, email address, and profile picture when available. It is not a blanket permission grant. If a plugin or connector then requests more access, that request is a separate review-and-approve screen the user sees on its own — so signing in and granting a plugin scopes are two distinct steps, and the user controls the second one. ### Should my startup add "Sign in with ChatGPT"? Decide by where your users already are. If your buyers are builders who live in ChatGPT and Codex, adding it lowers signup friction and — more valuably — lets your product be discovered and linked from inside that surface, which is a distribution channel, not just an SSO nicety. If your users are not ChatGPT-native, it mostly adds an identity dependency and a beta surface to maintain; wait for GA. Either way, add it as one federated option beside Google/Apple/GitHub, and never make it the only way in. ### How is this different from an MCP connector or an OAuth authorization for an agent? "Sign in with ChatGPT" authenticates a human — it establishes who the user is on your product. An MCP authorization or an agent OAuth flow authorizes software — it grants an agent a scoped, revocable token to act on a resource. They're complementary: the login gets a person into your app; the connector's separate consent step is what lets an agent then do things. Don't conflate the identity step with the capability grant — see our note on wiring [OAuth token exchange for agent delegation](/posts/how-to-wire-oauth-token-exchange-for-agent-delegation.html). ### Why does OpenAI want to be a login button? The same reason Google and Apple did: whoever owns the identity owns the top of the funnel. A login button turns ChatGPT into the place accounts are born, makes OpenAI the broker every partner integrates against, and pulls partner products onto OpenAI's surface where its users already are. Convenience for the user; gravity for the platform. The pattern is old — see [The OAuth Wall](/posts/2026-03-15-the-oauth-wall.html) — the agent era is just where it points next.
