OpenAI launches 'Sign in with ChatGPT' authentication service
OpenAI introduced a Sign in with ChatGPT feature that lets users authenticate to supported external applications using their ChatGPT account. The service, now available to all verified ChatGPT users, initially integrates with partners such as Notion, GitLab, Airtable and others, sharing only basic profile information. It marks OpenAI's entry into the digital identity space, positioning it against established single‑sign‑on providers.
