Git - git-credential-store Documentation

If not set explicitly with --file, there are two files where git-credential-store will search for credentials in order of precedence:

~/.git-credentials: User-specific credentials file.
$XDG_CONFIG_HOME/git/credentials: Second user-specific credentials file. If $XDG_CONFIG_HOME is not set or empty, $HOME/.config/git/credentials will be used. Any credentials stored in this file will not be used if ~/.git-credentials has a matching credential as well. It is a good idea not to create this file if you sometimes use older versions of Git that do not support it.

For credential lookups, the files are read in the order given above, with the first matching credential found taking precedence over credentials found in files further down the list.

Credential storage will by default write to the first existing file in the list. If none of these files exist, ~/.git-credentials will be created and written to.

When erasing credentials, matching credentials will be erased from all files.
