Open Source C# Version Control Software

Git Credential Manager (GCM) is a secure Git credential helper built on .NET that runs on Windows, macOS, and Linux. It aims to provide a consistent and secure authentication experience, including multi-factor auth, to every major source control hosting service and platform. GCM supports (in alphabetical order) Azure DevOps, Azure DevOps Server (formerly Team Foundation Server), Bitbucket, GitHub, and GitLab. Compare to Git's built-in credential helpers (Windows: wincred, macOS: osxkeychain, Linux: gnome-keyring/libsecret), which provide single-factor authentication support for username/password only. GCM replaces both the .NET Framework-based Git Credential Manager for Windows and the Java-based Git Credential Manager for Mac and Linux. Git Credential Manager is currently available for Windows, macOS, and Linux*. GCM only works with HTTP(S) remotes; you can still use Git with SSH.

Git Credential Manager for Windows is no longer being maintained. The cross-platform Git Credential Manager Core (GCM Core) is the official replacement. GCM Core is included as an optional component of Git for Windows 2.28 and will be made the default credential helper as of Git for Windows 2.29. GitHub will disable password-based authentication on APIs Git Credential Manager for Windows uses to create tokens. As a result, GCM for Windows will no longer be able to create new access tokens for GitHub. Git Credential Manager Core (GCM Core) supports OAuth-based authentication with GitHub and is the replacement for GCM for Windows. The Git Credential Manager for Windows (GCM) provides secure Git credential storage for Windows. It's the successor to the Windows Credential Store for Git (git-credential-winstore), which is no longer maintained. Compared to Git's built-in credential storage for Windows (wincred).
