It's not about the account because the account isn't even validated yet, clicking on the link given, success, claude.com gives out the Token, then can't copy it back to Terminal (any terminal, tmux/ttyd/bash/vscode...)
Tried to contact Anthropic about it but the chatbot is unhelpful, hoping that they'll notice by posting here because we are probably talking about thousand of users stuck here. Typing the code (although very annoying) doesn't seem to work as well because it "validates" it after typing maybe half of it and just early return.
To be clear, pasting does work anywhere else than the specific OAuth frame with `Browser didn't open? Use the url below to sign in (c to copy)`.
Anthropic, what are you doing?
It's a regression from Claude Code team, you must downgrade your version now to login `npm install -g @anthropic-ai/claude-code@2.1.101`.
Warning everyone: Do not log-out as you'll not be able to Login anymore, this isn't a downtime, it's a Claude code issue (offline issue).
