I run Codex in multiple disposable sandboxes and OAuth is such a fucking pain. I vibe-coded a project which just stores/allocates/shuffles codex auth.json files around. I have a codex instance that I manually authenticate multiple times with browser OAuth, then copy that auth.json in a store from where it's distributed to the sandboxes. And sandbox codex sometimes refreshes the authorization, so when that happens I need to send that auth.json back to the central store. Madness.

One good thing GitHub Copilot has it that you can just give it a GH_TOKEN that is valid for 6 months and stop this browser login nonsense.
