A Complete Guide to Microsoft Git Credential Manager for Windows

Authentication should never get in the way of your development workflow. If you frequently connect Git to hosting providers like GitHub, Azure DevOps, or Bitbucket, typing your username and password or managing complex SSH keys can become tedious.

Microsoft Git Credential Manager (GCM) for Windows solves this problem. It securely automates your authentication, letting you focus on your code. What is Git Credential Manager?

Git Credential Manager is an open-source tool created by Microsoft. It integrates with Git to securely store your repository credentials in your operating system’s native credential store. On Windows, it saves your login details directly into the Windows Credential Manager. Why Use GCM?

Multi-Factor Authentication (MFA): It fully supports modern authentication workflows, including 2-factor authentication and hardware tokens.

Personal Access Tokens (PATs): GCM automatically generates and manages PATs on your behalf, so you do not have to create them manually.

Cross-Platform: While originally built for Windows, GCM now natively supports macOS and Linux.

Multiple Host Support: It works out of the box with GitHub, GitLab, Azure DevOps, and Bitbucket. Prerequisites and Installation

To use GCM on Windows, you must first install Git for Windows. Step 1: Install Git for Windows

The easiest way to get GCM is to download the standard Git for Windows installer. During the installation wizard, you will see a screen asking you to choose a credential helper.

Make sure “Git Credential Manager” is selected. The installer will automatically configure Git to use GCM. Step 2: Manual Installation (Alternative)

If you already have Git installed without GCM, or if you want to update it independently, you can use the Windows Package Manager (winget): winget install GitHub.GitCredentialManager Use code with caution.

Alternatively, you can download the latest .exe installer directly from the official GitHub releases page. Configuration and Usage

Once installed, GCM operates entirely in the background. You do not need to launch a separate app to use it. Your First Push or Pull

The next time you interact with a remote repository using an HTTPS URL (for example, running git push or git pull), GCM will trigger a popup window.

A browser window or dialog box will open asking you to log into your provider (e.g., GitHub). Enter your credentials and complete any MFA requirements.

GCM securely captures the authorization token and passes it back to Git.

Your command will finish executing, and you will not see this login prompt again for this provider unless your token expires or changes. Verifying GCM is Active

To check if Git is correctly routed to use GCM, run the following command in your terminal: git config –global credential.helper Use code with caution.

If it is configured correctly, the terminal will return manager. Managing Your Stored Credentials

Because GCM stores your tokens inside the Windows Credential Manager, you can easily view, edit, or delete them if your password changes or your token expires.

Open the Windows Start Menu and search for “Credential Manager”. Click on Windows Credentials. Scroll down to the Generic Credentials section.

Look for entries starting with git:https://github.com or your respective hosting provider.

Click on the entry to see details, Edit the password, or click Remove to clear the cache. Common Troubleshooting Tips

While GCM is highly reliable, you may occasionally run into minor configuration conflicts. The Authentication Loop

If Git repeatedly asks you to log in even after a successful sign-in, your cached token might be corrupted. Open the Windows Credential Manager (using the steps above), locate the entry for your repository provider, delete it, and try your git push command again to force a fresh login. Disabling the Browser Popup

If you work in an environment where a web browser is not available, you can force GCM to use a device code login workflow instead. Run the following command: git config –global credential.github.authModes “device” Use code with caution.

This will output a short code in your terminal, which you can enter into a browser on a separate device (like your phone) to complete the login process. Conclusion

The Microsoft Git Credential Manager for Windows is an essential tool for modern developers. By replacing vulnerable plaintext passwords with securely managed tokens and supporting modern MFA, it bridges the gap between strong DevOps security and a seamless developer experience.
