プロジェクトの歴史

The helper entered Git's contrib area in 2016. Its initial Git commit describes it as based on the earlier GNOME Keyring helper, replacing the deprecated, GNOME-specific libgnome-keyring library with libsecret and the XDG Secret Service API.

Later Git-side changes kept the helper aligned with Git's credential protocol. A 2017 change made it unlock locked secrets through the Secret Service interface, and 2023 changes added storage for password expiry and OAuth refresh-token attributes while preserving compatibility with older stored credentials.

採用の歴史

Git's credential-helper documentation lists git-credential-libsecret alongside macOS Keychain and Windows Credential Manager as the Linux secure persistent storage option. That placement made it part of the standard Git credential-helper ecosystem rather than a standalone password-manager integration.

Linux package managers expose it as a separate package because the helper depends on libsecret and desktop secret-service libraries that are not always part of a minimal Git build.

使われ方

Practitioners configure it through Git's `credential.helper` setting, usually in `~/.gitconfig`, `$XDG_CONFIG_HOME/git/config`, or a repository `.git/config`. After configuration, Git invokes `git credential-libsecret` through the credential-helper protocol during HTTP authentication.

Its use case is workstation Git over HTTPS: the first authentication stores a username and password, personal access token, or generated token in the desktop secret service, and later fetch, pull, and push operations retrieve it without prompting.

パッケージ好きにとっての重要性

For package maintainers, git-credential-libsecret is a small but important split from the main Git package. It is tied to desktop-secret-service dependencies, so distributing it separately keeps headless or minimal Git installs lean while giving Linux desktop users OS-integrated credential storage.

It also illustrates Git's extension model: a helper in `contrib/credential` can become a distro-facing executable without changing Git's core credential protocol.

タイムライン

• 2016: Git adds `contrib/credential/libsecret` as a libsecret replacement for the GNOME Keyring helper.
• 2017: The helper learns to unlock locked Secret Service items when reading credentials.
• 2023: The helper stores Git credential attributes such as password expiry and OAuth refresh tokens in a backwards-compatible secret format.
• 2025: Git fixes compilation of the libsecret helper in contrib.
