Desktop OAuth
Codex
Official Codex desktop OAuth — same PKCE loopback flow as Codex CLI/Desktop (localhost:1455).
Failure
One OAuth for every AI app.
Users connect Codex, Antigravity, GitHub Copilot, Xiaomi MiMo, Claude Code, Grok Build, and Kimi Code once. Your app gets PKCE tokens, live models, thinking levels, and provider credentials.
What ships
Identity in, providers out.
Failure is the authorization server. Apps never re-implement every provider OAuth dance — they ask for `providers` scope and receive usable credential packages.

Device OAuth
