Microsoft recently announced the open-source release of the Git Credential Manager for Mac and Linux. This follows the release of the GCM for Windows. The tool was ported to Mac and Linux to simplify their authentication to remote Git repositories, in particular those hosted in Visual Studio Team Services (VSTS). The GCM is a Git credential helper that assists with multi-factor authentication. Compared to Git’s built-in credential storage (such as wincred for Windows), which provides single-factor authentication support for remote Git repositories, the GCM provides multi-factor authentication support for VSTS (and soon GitHub).
