user.name:: user.email:: author.name:: author.email:: committer.name:: committer.email:: The `user.name` and `user.email` variables determine what ends up in the `author` and `committer` field of commit objects. If you need the `author` or `committer` to be different, the `author.name`, `author.email`, `committer.name` or `committer.email` variables can be set. Also, all of these can be overridden by the `GIT_AUTHOR_NAME`, `GIT_AUTHOR_EMAIL`, `GIT_COMMITTER_NAME`, `GIT_COMMITTER_EMAIL` and `EMAIL` environment variables. See linkgit:git-commit[1] for more information. user.useConfigOnly:: Instruct Git to avoid trying to guess defaults for `user.email` and `user.name`, and instead retrieve the values only from the configuration. For example, if you have multiple email addresses and would like to use a different one for each repository, then with this configuration option set to `true` in the global config along with a name, Git will prompt you to set up an email before making new commits in a newly cloned repository. Defaults to `false`. user.signingKey:: If linkgit:git-tag[1] or linkgit:git-commit[1] is not selecting the key you want it to automatically when creating a signed tag or commit, you can override the default selection with this variable. This option is passed unchanged to gpg's --local-user parameter, so you may specify a key using any method that gpg supports.
