What is it?

Git Credential Manager (GCM) is a Git credential helper that runs on Windows, macOS and Linux. It is invoked automatically by Git when a remote requires authentication, opening a sign-in flow where needed and storing the resulting credentials or tokens for later reuse until they expire.

Unlike Git's built-in helpers, which only handle username and password, GCM supports multi-factor authentication and OAuth-based sign-in for Azure DevOps, Azure DevOps Server, Bitbucket, GitHub (including GitHub Enterprise Server) and GitLab. Credentials are kept in platform-specific secure stores, and it supports Entra authentication with broker integration on supported platforms.

The project replaces the older Git Credential Manager builds for Windows and for Mac and Linux. It works with HTTP(S) remotes; SSH authentication is configured separately through each host.

Key features

  • 02Credentials stored in platform-native secure credential stores
  • 03Supports Azure DevOps, Azure DevOps Server, Bitbucket, GitHub and GitLab
  • 04Works on Windows, macOS and Linux, including ARM64
  • 05Proxy configuration support for network environments

Use cases

  • Signing in to GitHub or Azure Repos from git push without managing tokens by hand
  • Using a single credential helper across Windows, macOS and Linux development machines
  • Connecting to self-hosted GitHub Enterprise Server or Azure DevOps Server instances
