Github Copilot interactive login

[Midwayne]

Question

I'm having issues with using Github Copilot as my provider. I want to be able to use the interactive login rather than providing the api key since I don't have access for the same in my company. I recall that the "Github deployment type" option used to show up before, but now it just asks me to enter my API key.

Any idea on how I could use github.com rather than enter my API key?

This issue might be a duplicate of existing issues. Please check:

• Github Enterprise authorization #3936: Github Enterprise authorization - Users attempting GitHub Enterprise login with GitHub Copilot are experiencing device authorization failures and encountering missing deployment type selection options

Feel free to ignore if your specific case differs from these issues.

Yes, this interactive login option absolutely exists, and it's integrated into opencode via the opencode-copilot-auth plugin. You should see an authentication option called login with github copilot not just api key.

You can try:

1. Checking if default plugins are disabled (env variable OPENCODE_DISABLE_DEFAULT_PLUGINS)
2. Running opencode -> /models -> ctrl + a (to add a provider) and then configure

If these don't work, try adding the plugin explicitly in your opencode.json:

{
  "plugin": ["opencode-copilot-auth@0.0.9"]
}

I just had the same issue - after some debugging I found that opencode was trying to download the plugins and failing (because of some config I had in my ~/.npmrc).

If you try to run opencode --print-logs auth login, you might see something like this:

opencode --print-logs auth login
(...)

Note the error with an HTTP 401.

If that's your case, you can temporarily rename the ~/.npmrc just to see if it starts working.

@mcking-07 I tried the steps you shared and still hit the issue, so I raised a issue.

@PerGon Thanks, this worked. It looks like the failure was caused by my company registry configured in .npmrc. As a temporary workaround, I switched the registry to the default npm registry during setup and then reverted it afterward.
