Git Credential Manager Core (GCM Core) is a secure Git credential helper built on .NET Core that runs on Windows and macOS. Linux support is in an early preview.
Compared to Git's built-in credential helpers (Windows: wincred, macOS: osxkeychain, Linux: gnome-keyring) which provides single-factor authentication support working on any HTTP-enabled Git repository, GCM Core provides multi-factor authentication support for Azure DevOps, Azure DevOps Server (formerly Team Foundation Server), GitHub, and Bitbucket.
Git Credential Manager Core (GCM Core) replaces the .NET Framework-based Git Credential Manager for Windows (GCM), and the Java-based Git Credential Manager for Mac and Linux (Java GCM), providing a consistent authentication experience across all platforms.
Git Credential Manager Core is currently available for macOS and Windows, with Linux support in preview. If the Linux version of GCM Core is insufficient then SSH still remains an option:

Notes:
(*) Currently only supported when using Git from the terminal or command line. A platform-native UI experience is not yet available, but planned.
(**) Debian package offered but not yet available on an official Microsoft feed.

The preferred installation mechanism is using Homebrew; we offer a Cask in our custom Tap.
To install, run the following:
brew tap microsoft/git
brew cask install git-credential-manager-coreAfter installing you can stay up-to-date with new releases by running:
brew upgrade git-credential-manager-coreIf you have an existing installation of the 'Java GCM' on macOS and you have installed this using Homebrew, this installation will be unlinked (brew unlink git-credential-manager) when GCM Core is installed.
To uninstall, run the following:
brew cask uninstall git-credential-manager-coreWe also provide a .pkg installer with each release. To install, double-click the installation package and follow the instructions presented.
To uninstall, run the following:
sudo /usr/local/share/gcm-core/uninstall.shDownload the latest .deb package, and run the following:
sudo dpkg -i <path-to-package>
git-credential-manager-core configureNote that Linux distributions require additional configuration to use GCM Core.
Download the latest tarball, and run the following:
tar -xvf <path-to-tarball> -C /usr/local/bin
git-credential-manager-core configureYou can download the latest installer for Windows. To install, double-click the installation package and follow the instructions presented.
GCM Core installs side-by-side any existing Git Credential Manager for Windows installation and will take precedence over it and use any existing credentials so you shouldn't need to re-authenticate.
To uninstall, open the Settings app and navigate to the Apps section. Select "Git Credential Manager Core" and click "Uninstall".
To uninstall, open Control Panel and navigate to the Programs and Features screen. Select "Git Credential Manager Core" and click "Remove".
Git Credential Manager Core is called implicitly by Git, when so configured. It is not intended to be called directly by the user.
For example, when pushing (git push) to Azure DevOps, a window is automatically opened and an OAuth2 flow is started to get your personal access token.
