OpenAI is exploring a new frontier in consumer technology: allowing users to sign in to third-party apps using their ChatGPT credentials. A new page quietly published on the company’s website this week reveals that OpenAI is inviting developers to express interest in integrating this authentication feature into their own platforms.
With ChatGPT now boasting an estimated 600 million monthly active users, OpenAI appears to be positioning itself not just as an AI provider, but as a foundational layer for digital identity — following in the footsteps of tech giants like Google, Apple, and Microsoft, all of which offer streamlined sign-in solutions across the web.
From AI Chatbot to Consumer Identity Layer
The potential feature — dubbed “Sign in with ChatGPT” — could provide users a faster and more seamless way to access external apps using their existing ChatGPT accounts. Beyond convenience, this move could help OpenAI extend its brand and presence deeper into e-commerce, social platforms, developer tools, and even smart devices.
Earlier this month, OpenAI began testing the waters by rolling out a limited preview of the feature through Codex CLI, its open-source terminal-based coding tool. The integration allowed developers to link their ChatGPT Free, Plus, or Pro accounts to OpenAI’s API infrastructure — with added incentives: $5 in API credits for Plus users and $50 for Pro users.
A Call for Developers of All Sizes
OpenAI’s interest form for developers signals ambitions for wide adoption. The form caters to teams ranging from startups with under 1,000 users to apps servicing 100+ million users weekly. It also probes whether these companies are already paying customers of the OpenAI API and how they monetize AI features.
“We’re looking to support apps at every scale,” the company notes, suggesting OpenAI aims to make its identity feature relevant both for indie developers and global platforms.
This isn’t the first time OpenAI has hinted at plans to expand its identity offerings. CEO Sam Altman floated the idea of a “Sign in with OpenAI” function back in 2023. While the concept has lingered in the background, the company now seems to be actively building it out in 2025.
What This Could Mean
If fully deployed, “Sign in with ChatGPT” could:
Still, many questions remain: When will the sign-in option become widely available? Which companies will adopt it first? And how will it handle user privacy, consent, and cross-platform authentication?
At time of publishing, OpenAI had not responded to inquiries about the rollout timeline or initial partners.
But one thing is clear: OpenAI isn’t content to stay in the chatbot box. With identity, infrastructure, and authentication now in play, the company is increasingly shaping not just how we use AI — but how we log in to the internet itself.

If fully deployed, “Sign in with ChatGPT” could:
- Streamline user onboarding for AI-powered tools.
- Encourage developers to embed more OpenAI integrations in their apps.
- Create new data-sharing and personalization opportunities (raising privacy and ethics considerations).
- Position OpenAI as a central player in the identity and access management (IAM) space, beyond just AI APIs.
