| # Git Credential Manager | |
| [![Build Status][build-status-badge]][workflow-status] | |
| --- | |
| [Git Credential Manager][gcm] (GCM) is a secure | |
| [Git credential helper][git-credential-helper] built on [.NET][dotnet] 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], Azure DevOps | |
| Server (formerly Team Foundation Server), Bitbucket, GitHub, and GitLab. | |
| Compare to Git's [built-in credential helpers][git-tools-credential-storage] | |
| (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][gcm-for-windows] and the Java-based | |
| [Git Credential Manager for Mac and Linux][gcm-for-mac-and-linux]. | |
| ## Install | |
| See the [installation instructions][install] for the current version of GCM for | |
| install options for your operating system. | |
| ## Current status | |
| 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: | |
| - [Azure DevOps SSH][azure-devops-ssh] | |
| - [GitHub SSH][github-ssh] | |
| - [Bitbucket SSH][bitbucket-ssh] | |

| (\*) GCM guarantees support only for [the Linux distributions that are officially | |
| supported by dotnet][dotnet-distributions]. | |
| ## Supported Git versions | |
| Git Credential Manager tries to be compatible with the broadest set of Git | |
| versions (within reason). However there are some know problematic releases of | |
| Git that are not compatible. | |
| - Git 1.x | |
| The initial major version of Git is not supported or tested with GCM. | |
| - Git 2.26.2 | |
| This version of Git introduced a breaking change with parsing credential | |
| configuration that GCM relies on. This issue was fixed in commit | |
| [`12294990`][gcm-commit-12294990] of the Git project, and released in Git | |
| 2.27.0. | |
| ## How to use | |
| Once it's installed and configured, Git Credential Manager is called implicitly | |
| by Git. You don't have to do anything special, and GCM isn't intended to be | |
| called directly by the user. For example, when pushing (`git push`) to | |
| [Azure DevOps][azure-devops], [Bitbucket][bitbucket], or [GitHub][github], a | |
| window will automatically open and walk you through the sign-in process. (This | |
| process will look slightly different for each Git host, and even in some cases, | |
| whether you've connected to an on-premises or cloud-hosted Git host.) Later Git | |
| commands in the same repository will re-use existing credentials or tokens that | |
| GCM has stored for as long as they're valid. | |
| Read full command line usage [here][gcm-usage]. | |
