<AccordionGroup>
  <Accordion title="Can't finish GitHub sign-in?">
    1. Confirm you can open [github.com](https://github.com)
    2. Sign in to GitHub in the browser first, then authorize in Starcat
    3. If corporate networks block the callback, use a PAT instead\
       See [GitHub connection](/getting-started/github-connection).
  </Accordion>

  <Accordion title="Getting Started sync never checks off after sign-in?">
    You must **tap Sync** on the toolbar yourself. See [Quickstart](/getting-started/quickstart).
  </Accordion>

  <Accordion title="Token / session expired (401)?">
    Sign in again when prompted; PAT users create a new token on GitHub and paste it in.
  </Accordion>

  <Accordion title="How do I switch GitHub accounts?">
    Sidebar avatar → Sign out → sign in with the new account. Data is isolated per account.
  </Accordion>

  <Accordion title="What PAT scopes are needed?">
    Classic token common case: `read:user` + `public_repo`. For fine-grained tokens, grant read-only access to user profile and public repo metadata per GitHub's current options.
