Was ist Git Credential Manager ?

Git Credential Manager (GCM) ist die Eingabeaufforderung für Benutzername und Kennwort in Git.
Das Git-Projekt hat den .NET Framework-basierten Git Credential Manager for Windows und den Java-basierten Git Credential Manager for Mac and Linux zum plattformunabhängigen Git Credential Manager Core (GCM Core) zusammengeführt. Dieser basiert auf .NET Core.

----
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 provide 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.

Q: How does this project relate to Git Credential Manager for Windows and Git Credential Manager for Mac and Linux?
Git Credential Manager for Windows (GCM Windows) is a .NET Framework-based Git credential helper which runs on Windows. Likewise the Git Credential Manager for Mac and Linux (Java GCM) is a Java-based Git credential helper that runs only on macOS and Linux. Although both of these projects aim to solve the same problem (providing seamless multi-factor HTTPS authentication with Git), they are based on different codebases and languages which is becoming hard to manage to ensure feature parity.

Git Credential Manager Core (GCM Core; this project) aims to replace both GCM Windows and Java GCM with a unified codebase which should be easier to maintain and enhance in the future.

Q: Does this mean GCM for Windows (.NET Framework-based) is deprecated?
Yes. Git Credential Manager for Windows (GCM Windows) is no longer receiving updates and fixes. All development effort has now been directed to GCM Core. GCM Core is available as a credential helper option in Git for Windows 2.28, and will be made the default helper in 2.29.

Q: Does this mean the Java-based GCM for Mac/Linux is deprecated?
Yes. Usage of Git Credential Manager for Mac and Linux (Java GCM) should be replaced with GCM Core or SSH keys. If you wish to install GCM Core on macOS or Linux, please follow the download and installation instructions.
