ChatGPT is quickly becoming one of the largest consumer applications in the world, now with roughly 600 million monthly active users. To capitalize on this popularity, OpenAI seems eager to try and expand into other consumer areas, such as online shopping, social media, and personal devices. A potential “Sign in with ChatGPT” feature could help OpenAI compete with other massive consumer technology companies — such as Apple, Google, and Microsoft — that help people with a wide range of online services, including a quick way to sign in to third-party apps.

Earlier this month, OpenAI launched a preview of the “Sign in with ChatGPT” experience for developers in Codex CLI, the company’s open source AI coding tool for terminals. The feature let developers connect their ChatGPT Free, Plus, or Pro accounts to their API accounts. OpenAI offered Plus users $5 in API credits to sign in with ChatGPT, and Pro users $50 in API credits.

OpenAI seems to be interested in integrating the sign-in service with a broad array of companies. The developer interest form asks for companies to specify their app’s user base, ranging from tiny companies with fewer than 1,000 weekly users to massive apps with over 100 million weekly users. The form also asks developers how they charge for AI features today and whether they’re customers of the OpenAI API.

CEO Sam Altman noted in 2023 that the company may look into a “sign in with OpenAI” feature in 2024. However, it now appears OpenAI is more seriously building out the capability today, in 2025. It’s unclear when the sign-in feature would go live for users of ChatGPT or how many companies have signed up to be part of it.

OpenAI did not immediately respond to TechCrunch’s request for comment.
