OpenAI wants to turn ChatGPT into more than a chatbot. At its DevDay conference in San Francisco on Tuesday, Sam Altman showed off “Sign in with ChatGPT,” a login that lets people use their ChatGPT account inside other services and, if they want, carry their subscription with them.
The login itself is already in beta and has been for a while. OpenAI says it launched in July with Airtable, GitLab, HubSpot, Notion, Supabase and Vercel, then opened to all users two weeks ago. The bigger shift at DevDay was the subscription part: apps can now tap into a user’s ChatGPT allowance instead of forcing a separate sign-up or a fresh API key.
OpenAI named 16 launch partners for that setup, most of them A.I. coding tools. The list includes Cognition’s Devin, Warp, Amp, Kilo Code, OpenCode, OpenClaw, T3, Notion and Vercel, with Lovable set to join soon. The missing names matter just as much. Grok, Claude and Google’s own services don’t offer a ChatGPT login, which is not exactly a shock when they’re chasing the same users and the same subscription money.
For a plain sign-in, apps get only a user’s name, email address and profile picture. Chat histories, memories, files and billing data stay put. But OpenAI still learns plenty from the login itself, including app details, IP addresses, device identifiers and other security signals it says it uses for authentication and fraud prevention. That gives OpenAI a cleaner view of where its users spend time outside ChatGPT, and that is the real prize.
The financial logic is simple. ChatGPT Plus and Pro users can let an app charge A.I. requests against their existing plan, with separate limits per app and no extra volume added to the account. Once the allowance is used up, the app stops rather than quietly rolling over to its own billing. In Business and Enterprise, an admin has to approve it first. And yes, the old trick is obvious: make the login useful enough that the subscription starts to feel like a master key.
My take — AI-written commentary, not fact-checked reporting
This is less a login feature than a power grab with a friendly face. OpenAI is copying the Google playbook because that playbook works: once the account becomes the key, the budget, and the default, everyone else gets smaller. Developers will call it convenience; platform people call it leverage.
