OpenAI is considering allowing users to sign in to third-party applications using their ChatGPT accounts, according to a company web page published on Tuesday. The company is soliciting interest from developers to integrate this service.
ChatGPT currently has approximately 600 million monthly active users globally. OpenAI appears to be exploring opportunities to expand into sectors such as online shopping, social media, and personal devices. The potential “Sign in with ChatGPT” feature could position OpenAI as a competitor to companies like Apple, Google, and Microsoft, which offer sign-in services to third-party apps.
Earlier in May 2025, OpenAI launched a preview of the “Sign in with ChatGPT” experience for developers in Codex CLI, its AI coding tool for terminals. This feature allowed developers to connect their ChatGPT Free, Plus, or Pro accounts to their API accounts. OpenAI offered Plus users $5 in API credits and Pro users $50 in API credits for using this sign-in feature.
OpenAI’s ChatGPT just refused to die
According to a post on X from user Nick Dobos, a “Sign in with ChatGPT” feature is imminent. Dobos stated, “sign in with chatGPT is about to be EVERYWHERE.”
OpenAI’s developer interest form requests that companies specify their app’s user base, ranging from companies with fewer than 1,000 weekly users to apps with over 100 million weekly users. The form also inquires about how developers currently charge for AI features and whether they utilize the OpenAI API.
CEO Sam Altman indicated in 2023 the possible development of a “sign in with OpenAI” feature in 2024. The company is now actively developing this capability in 2025. The release date for ChatGPT users and the number of participating companies remain unknown.
