Sign in with ChatGPT Brings Plans to Apps
OpenAI’s new identity-provider flow lets users sign into supported apps with their ChatGPT account and optionally authorize eligible AI requests against their ChatGPT Plus or Pro plan. Developers can offer AI-powered tools without requiring users to create API keys.
This is a significant shift from OpenAI merely selling model access to becoming an identity, distribution, and billing layer for third-party AI apps.
- –Open-source and local tools can reduce onboarding friction by letting users bring an existing ChatGPT plan instead of configuring API credentials.
- –Identity and plan usage are separate permissions, while conversations, memories, and API keys remain private to ChatGPT.
- –Per-app weekly limits give users control, but shared plan allowances could make usage costs and capacity less predictable.
- –The initial rollout favors open-source projects and selected partners, so it complements rather than replaces the OpenAI API for commercial developers.
- –Dynamic client registration and host identifiers make the integration practical for desktop apps, coding tools, and other locally run software.
