openai launches "sign in with chatgpt" across major dev tools

Every time you sign up for a new dev tool, muscle memory usually directs you toward "Sign in with Google" or "Sign in with GitHub."

Now, OpenAI is staking its claim on that login screen.

OpenAI rolled out "Sign in with ChatGPT," a full identity-provider service that lets you create and access third-party accounts using your ChatGPT credentials. It is available globally for personal users and Enterprise organizations alike.

The launch partners form an impressive roster of heavy-hitting dev and productivity platforms, including Notion, GitLab, Vercel, Airtable, Supabase, and HubSpot. It is also live on OpenAI Academy and ChatGPT Sites, with rollouts hitting select plugins.

Strict privacy lines right out of the box

Whenever an AI platform steps into identity authentication, the immediate red flag is obvious: are my private prompts and messy chat threads about to leak to external apps?

OpenAI made sure to preempt that freakout. Under the standard identity sign-in flow, the external tool receives only your name, email address, and profile picture.

It explicitly does not share your ChatGPT conversations, your memory, your uploaded files, your tokens, or any billing information. Those remain locked down.

If a service genuinely requires deeper hooks—like HubSpot needing access to a ChatGPT Ads account—it has to trigger a completely separate, explicit permissions flow. For workspace members, tenant admins in the OpenAI Admin Console can set organizational policies, ensuring individual logins don't accidentally bypass company security postures.

Bringing your subscription along for the ride

While single sign-on is handy, the real kicker here is subscription sharing.

Select partners allow you to apply the usage limits, rates, and credits included in your ChatGPT subscription directly inside their third-party tools. Instead of paying every single SaaS vendor an extra AI markup or juggling separate API keys, you can authorize a participating app to tap into your existing plan's quota.

You retain granular controls over how much usage the partner tool can consume, and approving token usage still does not give the tool access to your chats or memories.

Why it matters

We see this as a calculated move by OpenAI to graduate from a standalone chat destination into foundational internet plumbing.

For daily users, the convenience is immediate. If you already pay for a ChatGPT plan, being able to carry those model limits directly into your Notion docs or GitLab pipelines eliminates redundant billing and clumsy API setups.

For the broader industry, it is a direct shot at the digital identity moat long held by Google, Microsoft, and GitHub. Becoming an identity provider is the ultimate form of ecosystem lock-in; once users tether dozens of everyday work apps to their ChatGPT login, switching to Claude or another competing model becomes vastly more painful.

It is a remarkably clever play. By keeping conversations strictly isolated, OpenAI neutralizes privacy pushback, while using subscription sharing to turn third-party SaaS apps into eager distribution nodes for its own ecosystem.
