OpenAI Explores ‘Sign In with ChatGPT’ for Third-Party Apps
OpenAI is testing a groundbreaking authentication feature that could allow users to log into third-party apps using their ChatGPT credentials. The company recently published a developer interest form to gauge potential adoption of this service.
Why This Matters for Digital Authentication
With approximately 600 million monthly active users, ChatGPT has become one of the world’s most popular consumer applications. This move positions OpenAI to compete with tech giants like Apple, Google, and Microsoft in the authentication space while expanding its ecosystem into:
- E-commerce integrations
- Social media platforms
- Personal device ecosystems
Current Developer Preview
OpenAI has already launched a limited preview of the feature in Codex CLI, their open-source AI coding tool. Key details of the preview include:
- Available for ChatGPT Free, Plus, and Pro accounts
- Offered $5 API credits for Plus users
- Provided $50 API credits for Pro users
“Bigger deal than people are realizing - sign in with chatGPT is about to be EVERYWHERE”
— Nick Dobos (@NickADobos)
Broad Implementation Strategy
The developer interest form reveals OpenAI’s ambitious plans:
- Seeks partners across all company sizes (from ,000 to 100M+ weekly users)
- Asks about current AI monetization strategies
- Inquires about existing OpenAI API usage
Timeline and Availability
While CEO Sam Altman first mentioned this concept in 2023, development appears to have accelerated in 2025. However, OpenAI hasn’t disclosed:
- Official launch timeline
- Current partner adoption rates
- Specific implementation details
TechCrunch reports that OpenAI hasn’t responded to requests for additional comment.
This authentication solution could fundamentally change how users interact with AI-powered services across the web, creating a more seamless digital experience while expanding OpenAI’s ecosystem reach.
