git authentication

This tag collects discussion of git authentication as it affects developers working with GitHub and other Git hosts, especially when credentials, tokens, or SSH keys determine whether a clone or fetch succeeds. The tagged content focuses on GitHub's announcement that it may temporarily require authentication for anonymous HTTPS clones and fetches of public repositories during periods of unusual traffic, and what that means for build jobs, scripts, and developer machines that pull public code without credentials. Coverage includes CI fixes and workarounds for pipelines that could fail without warning, making this a useful reference for anyone troubleshooting or hardening automated Git workflows on Windows.
