Supabase Auth now supports X/Twitter OAuth 2.0 authentication, replacing the legacy OAuth 1.0a flow. The new provider offers improved security with PKCE support and requires setting up an OAuth 2.0 app in the X Developer Portal, enabling email requests, and configuring credentials in the Supabase dashboard. Users currently on the legacy Twitter OAuth 1.0a provider are recommended to migrate to the new implementation.
