Sign in with ChatGPT: OpenAI Wants to Become Your Identity on the Web
After Google and Apple, OpenAI is launching its own login button, with the added twist of letting you share your ChatGPT subscription with third-party tools.
In brief
OpenAI is rolling out "Sign in with ChatGPT," a login option that lets you use your ChatGPT account to access external applications, with Airtable, GitLab, HubSpot, Notion, Supabase and Vercel as first partners. Beyond identity, some tools will be able to tap into the quota included in a ChatGPT subscription. It's one more step toward a ChatGPT that becomes an infrastructure layer, not just an app.
🍺 Bar-stool version
OpenAI wants your ChatGPT account to become your ID card for the web, like the "Continue with Google" button, except held by someone who already knows your 2am questions. Don't worry, Notion or GitLab only get your name, email and photo, not your existential conversations. The real deal is that these tools can also dip into your ChatGPT subscription to run their own AI, kind of like lending your cafeteria card to the whole office while setting a spending cap. And in tech, whoever controls the login button rarely stops at just the button.
Key takeaways
- 1
Sign in with ChatGPT is an identity provider: it lets you create, link, or access an account on an external app via your ChatGPT account.
- 2
First partners are Airtable, GitLab, HubSpot, Notion, Supabase and Vercel, in addition to OpenAI Academy and ChatGPT Sites.
- 3
The third-party app only receives name, email address, and profile photo: no conversations, no memory, no files, no billing data.
- 4
Some partner tools can separately request permission to use the OpenAI usage included in an eligible ChatGPT subscription, with limits set by the user.
- 5
Any additional delegated access (connected apps for ChatGPT Sites, ChatGPT Ads account for HubSpot) goes through a separate authorization flow.
- 6
On the enterprise side, the feature is enabled by default for organizations without an explicit identity policy; delegated access to Sites and Ads remains disabled by default during the admin preview.
- 7
OpenAI itself collects account identifiers, requested and granted permissions, IP address, inferred location, device identifiers, and security signals.
A Login Button Signed OpenAI
Sign in with ChatGPT works like the "Continue with Google" or "Sign in with Apple" buttons: on a partner site's login page, the user picks "Sign in with ChatGPT" or "Continue with ChatGPT," reviews the shared information, and confirms.
The service is available worldwide for all authenticated ChatGPT users, including in Enterprise organizations. It's already live on OpenAI Academy and ChatGPT Sites, and is gradually rolling out across partner plugins and sites.
The starting list leans heavily toward developer and productivity tools: Airtable, GitLab, HubSpot, Notion, Supabase and Vercel. The sign-in option also appears when connecting an app from the "ChatGPT plugin directory."
What the Third-Party App Sees
For sign-in alone, the application receives three pieces of information: name, email, and profile photo if there is one. OpenAI stresses what the button does not share: conversations, memory, files, tokens, billing data, or other account information.
An app can, however, subsequently request delegated access to specific data or actions. OpenAI cites two examples: a ChatGPT Site requesting access to connected apps, or HubSpot requesting access to the user's ChatGPT Ads account.
Each additional permission requires separate consent. The stated principle is clear: identity on one side, data access on the other.
Subscription Sharing, the Real Novelty
The most strategic point is almost slipped in casually: some partner tools can use the pricing, limits, and credits of the ChatGPT subscription for their own AI features.
After signing in, the tool can separately request permission to consume the OpenAI usage included in an eligible ChatGPT plan. The user controls and caps this consumption, and can certainly sign in without agreeing to this sharing.
OpenAI specifies that this "token sharing" grants no access to conversations or memory. In practice, the ChatGPT subscription becomes a kind of compute wallet usable elsewhere.
What OpenAI Collects on Its End
The page carefully distinguishes what the application receives from what OpenAI processes. To authenticate and secure the login, OpenAI collects account identifiers, email, authentication provider, and the selected workspace.
Added to this are authorization details (application ID, requested and granted permissions, decision, outcome) as well as technical data: session identifiers, IP address, location inferred from the request, browser version, user agent, device identifiers, and security signals.
In other words, OpenAI will know which applications its users sign into and with what permissions.
Enterprise-Side Controls
By default, Sign in with ChatGPT is enabled for organizations that haven't set an explicit identity policy. Existing allow lists or block lists remain in effect.
Management happens in the External access section of the OpenAI Admin Console, reserved for global admins: a workspace owner or admin doesn't automatically have this right.
During the admin preview for ChatGPT Business and Enterprise customers, delegated access for ChatGPT Sites and Ads is disabled by default and requires explicit approval, which does not replace each member's own authorization. Developers interested in integrating are invited to fill out a form.
“Subscription sharing does not give the tool access to your ChatGPT conversations or memory.”
“For identity sign-in, the external application receives only your name, email address, and profile picture, if you have one.”
“By default, Sign in with ChatGPT is enabled for organizations that have not set an explicit identity policy.”
Why it matters
Behind its technical help-page look, this document describes a platform ambition. The login button is one of the most powerful assets on the web: Google, Apple, and Facebook figured this out long ago, because it places the issuer at the center of user journeys and gives it visibility into the ecosystem. OpenAI, with hundreds of millions of accounts, is joining this club by first targeting developer and productivity tools. But the real novelty lies elsewhere: subscription sharing turns ChatGPT into a payment method for AI compute. For a Notion or a Vercel, it's a chance to offer AI without bearing the cost; for OpenAI, it's making the subscription harder to cancel and becoming the default provider of AI features for third parties. Two points deserve attention: the default activation in organizations without an explicit policy, which reverses the usual logic of enterprise caution, and the list of data OpenAI collects at each login, which gives it a detailed map of the tools its customers use. The stated separation between identity and delegated access is rigorous on paper; whether users will actually read every consent screen remains to be seen.
