## Examples

- Open the browser and authorize the CLI: 
  `circleci auth login`

  `circleci auth login --no-browser`
- Authenticate against a non-default host: 
  `CIRCLE_HOST=https://example.circleci.com circleci auth login`

## Details

Log in to CircleCI by opening the OAuth authorization page in your
browser. After you approve the request, an authorization code is
delivered back to a temporary loopback server on 127.0.0.1, then
exchanged for an access token via POST /oauth/token.

The token is saved to the system keyring (or to the YAML config
when --insecure-storage is set) and used automatically by all
subsequent CLI commands.
