Sign in with ChatGPT is now in beta on Supabase, allowing users to log in using their ChatGPT account.

This beta feature is available on the Supabase login page and through the Supabase plugin in ChatGPT across desktop, web, and mobile platforms. Users can create or link a Supabase account with their existing ChatGPT identity, simplifying the connection process. This integration reduces the number of steps needed to connect Supabase inside ChatGPT and Codex, streamlining account setup and management.
