OpenAI is testing the waters for a new feature that could expand its presence beyond its current AI chat interface. This week, the company revealed it is exploring a “Sign in with ChatGPT” service that would allow users to log in to third-party apps using their ChatGPT credentials, similar to how many users currently sign in with Google, Apple, or Microsoft accounts.
With ChatGPT reaching approximately 600 million monthly active users, OpenAI appears eager to leverage that massive user base to gain a foothold in broader consumer tech, from online shopping to social media and personal productivity apps.
OpenAI has already begun previewing this capability with developers. Earlier this month, a limited “Sign in with ChatGPT” experience was launched for Codex CLI, OpenAI’s open-source AI coding tool. Developers were invited to connect their ChatGPT Free, Plus, or Pro accounts to their API accounts, with Plus and Pro users receiving $5 and $50 in API credits, respectively, for doing so.
The company is currently gauging interest from developers through a form that asks for details such as app size, existing AI monetization strategies, and whether the app currently uses the OpenAI API. The form is open to companies of all sizes, from startups to apps with over 100 million weekly users.
CEO Sam Altman had previously mentioned a “sign in with OpenAI” feature back in 2023, but signs suggest that development on this idea has accelerated in 2025. While there is no official launch date yet, the move signals OpenAI’s ambition to expand from being a powerful AI tool to a foundational identity provider in the digital ecosystem.
