Best Practices for Managing Git Username and Email Configuration

When working across many repositories, keeping Git credentials organized is essential. Many developers set their Git usernames and email addresses globally. However, switching between work and personal projects needs a more flexible approach. Configuring these settings correctly helps prevent commit mix-ups and ensures a smooth workflow.

Some key areas are worth discussing:

  1. Many accounts handling: Do you rely on SSH keys, credential helpers, or .gitconfig to manage different Git identities?
  2. Privacy & Security: Have you ever faced issues with exposing personal email in commits? Do you use GitHub’s noreply email or GPG signing to protect your identity?
  3. Automation & Scripting: Have you set up automation to switch usernames and emails based on directories or who owns the repository? Are there any useful scripts or aliases that you rely on?
  4. CI/CD & Authentication: How can you set up Git credentials in deployment pipelines while ensuring they remain secure?

How do you handle commit authorship when many people work on a shared project on the same machine? Do you enforce local per-repo configurations, or is there a better way to handle this? I’m looking forward to your insights!

We had a dev commit with their personal id into a work project (just an internal utility project but no matter). We haven’t changed anything on server side but set policy that all clones require username as part of the URL and this works for now. We are not a huge team and generally good with these things so that works for us for now. We will be looking into a better solution at a later stage.
