Sign in with ChatGPT
An OAuth-based third-party authentication mechanism introduced by OpenAI that allows users to log into third-party applications using their ChatGPT accounts. It includes a special scope that authorizes third-party applications to consume the user's ChatGPT subscription quota.
Core Facts
The built-in authentication system of ChatGPT Sites is based on the ChatGPT account system, with team members logging in using their respective ChatGPT accounts.
Amp has entered a partnership with OpenAI, integrating multiple OpenAI models including GPT-6 Astra, Ultrafast, and GPT-Live-1, and supports connecting account systems through Sign in with ChatGPT.

Sign in with ChatGPT is essentially an OAuth-like identity authentication and authorization protocol extension, with an AI-specific layer added that allows token quotas to be granted.
The new scope for ChatGPT login mixes authorized access and authorized consumption within the same authorization flow, breaking the traditional OAuth assumption that scopes are only used for data access.
Teams integrating this button should treat it as a billing integration rather than a login integration, and invest engineering and product effort in transparency, limits, and revocability to the same standard applied to handling money.
Developers need to proactively set call caps, rate limits, and anomaly detection to avoid excessive calls that rapidly drain users' quotas.
The wording of the authorization flow must clearly distinguish between two types of permissions—reading identity and consuming quota—and the latter must not be buried within a standard login flow.
This design means application developers do not need to bear the cost of API calls themselves, and instead directly borrow the quota already paid for by the user.
This authorization model reflects a new distribution approach by AI platforms to turn user subscriptions into compute wallets that can be authorized for use by third parties.
This design lowers the barrier for developers to onboard, but transfers costs and potential abuse risks onto users.
Developers are advised to explicitly agree on call caps at the protocol level and to continuously track changes in platform policies.
