Check and see if ~/.local/state/opencode/plugin/copilot.ts exists on your system. Experienced the same issue and was able to fix it by copying that file over from one of my Linux machines where OAuth login is working.

I'm having the same issue. I do not have the file @zacharyeller13 mentioned. Completely fresh install from NPM.

I can't get it to prompt me for auth device flow at all, it always prompts for API key.

Edit: Setting "NODE_TLS_REJECT_UNAUTHORIZED=0" fixes this issue for me. It is due to corporate proxy. See #1694 for an issue asking for local trust store support.

I got the same issue (API key asked for Github Copilot) but it was due to a different root cause (silent failure to install npm deps).

Because of a custom npm registry configured on my side, the attempts to install the deps were getting 401 but I was getting 0 error on the UI so I did not know that something was wrong. Like described in this ticket I was then unable, to login to Github Copilot because it was asking for an API key.

Once I fixed my npm registry, everything went like a charm.

I'm guessing that the errors are not caught, that's why there is no error message on the UI. Maybe a good fix would be to display an error message when that happens?

Here's an extract of the logs, showing the 401.

I'm on MacOS, v1.1.14 installed with Homebrew.
