Using Git Credential Manager for Effortless Authentication

Tired of that annoying password prompt every time you interact with your remote Git repository? You're not alone! Constantly re-entering your credentials can break your flow and frankly, it's a bit of a drag.

Thankfully, there's a better way: Git Credential Manager (GCM). This handy tool securely stores your Git credentials, so you can focus on coding, not authentication.

Let's explore how to set it up for securely storing credentials and eliminating repetitive password prompts.

Understanding Git Credential Management

Why bother with credential management in the first place? Well, every time you push, pull, or clone from a remote repository, Git needs to verify your identity. Without a credential manager, it asks for your username and password repeatedly.

While you could store passwords in plain text (please don't!), GCM offers a much more secure and convenient solution.

Think of GCM as your Git's memory for passwords. It acts as a "credential helper," securely storing your login details after you enter them the first time. This means subsequent Git operations happen seamlessly in the background, without interrupting your work.

GCM uses your operating system's secure storage mechanisms (like the Windows Credential Manager or macOS Keychain) to keep your information safe. This integration is a big win for both convenience and security.

Installation and Configuration

Getting started with Git Credential Manager is straightforward. Here's how to set it up on different platforms:

• Windows: Head over to the official Git Credential Manager for Windows release page on GitHub and download the latest installer. Run the installer and follow the on-screen instructions. It's usually a simple "next-next-finish" process.

• macOS: The easiest way on macOS is often using Homebrew. If you have Homebrew installed, just open your Terminal and run:

    brew install git-credential-manager-core

  Alternatively, you can download the installer from the GCM core release page on GitHub.

• Linux: Installation methods vary depending on your distribution. Check the GCM Core documentation for specific instructions for your Linux flavor (Debian/Ubuntu, Fedora/CentOS, etc.). You might be able to install it via your distribution's package manager or by downloading a .deb or .rpm package.

Once installed, you need to tell Git to use GCM as your credential helper. Open your Terminal or Git Bash and run the following command:

git config --global credential.helper manager

That's it! Git is now configured to use Git Credential Manager.

Using Git Credential Manager in Practice

The next time you perform a Git operation that requires authentication (like your first git push after installing GCM), you'll be prompted for your username and password. Enter them as usual. GCM will securely store these credentials.

From that point forward, you can perform subsequent git push, git pull, git clone, and other authenticated Git commands without being asked for your credentials again. It just works! ✌️

Working with multiple Git hosting providers (like GitHub and GitLab) or different accounts is also handled smoothly. GCM will typically prompt you for credentials the first time you interact with a new remote requiring authentication and store them separately.

Advanced Topics and Considerations

GCM usually keeps your credentials stored until you explicitly tell it to forget them or your operating system's credential store manages them. For most developers, the default settings work perfectly.

Security is a top priority, and GCM leverages the security features of your operating system to protect your credentials. Make sure you have a strong password or use other robust authentication methods for your operating system to further enhance security.

If you ever need to clear the credentials stored by GCM, the process depends on your operating system:

Conclusion

Git Credential Manager is an excellent tool that removes the frustration of repeatedly entering your Git credentials. By securely storing your login information, it saves you time and allows you to focus on what matters. As you’ve seen, it is also very easy to set up.

So make sure you give GCM a try — you'll wonder how you ever managed without it.
