You do not need a login for local setup. GitHub sign-in is only for hosted review, private repo access, and team features.
The hosted platform is still beta/gated. Signing in helps connect your GitHub identity for supported hosted workflows, but access may still depend on current availability.
After sign-in: we will return you to the platform and, if your account has access, you can continue into hosted review flows. If not, you can still use local setup with no login required.
CVC only asks you to sign in when hosted capabilities matter. For local VS Code, MCP, or CLI setup, start with the setup guide instead.
