– OpenAI recently previewed the sign-in feature in Codex CLI, offering API credits to Plus and Pro users who tried it.

OpenAI is testing a new feature that could allow ChatGPT users to log into third-party apps using their existing accounts, marking a potential expansion into broader consumer services. The company recently posted a developer survey to assess interest in integrating this capability, signaling a strategic move to leverage ChatGPT’s massive user base—now approaching 600 million monthly active users—across other digital platforms.
This “Sign in with ChatGPT” functionality would position OpenAI alongside tech giants like Apple, Google, and Microsoft, which already offer streamlined authentication for apps and services. By enabling seamless logins for shopping, social media, or productivity tools, OpenAI could deepen user engagement while competing in the crowded identity management space.
A limited preview of the feature recently launched in Codex CLI, OpenAI’s terminal-based coding assistant, allowing developers to link their ChatGPT subscriptions to API accounts. Early adopters received incentives—$5 in API credits for Plus users and $50 for Pro users—hinting at how OpenAI might encourage broader adoption.
The company’s outreach suggests ambitions beyond niche applications. Its developer survey asks about company size, from startups with under 1,000 weekly users to platforms with over 100 million, along with questions about existing AI monetization strategies. This broad targeting indicates OpenAI envisions the login service spanning industries, though it remains unclear how many partners have committed.
While CEO Sam Altman floated the idea of an OpenAI login system in 2023, development appears to have accelerated this year. No official timeline exists for a public rollout, leaving questions about adoption rates and security safeguards unanswered. OpenAI has yet to comment on specifics, but industry observers predict the feature could soon become ubiquitous—transforming ChatGPT from an AI tool into a central hub for digital access.
