git credential manages stored authentication credentials. It interfaces with credential helpers to retrieve, store, and erase credentials for remote repositories.
The command is typically invoked automatically by Git during push/pull operations. Direct use is for debugging or scripting authentication. Credentials flow through configured helpers (cache, store, osxkeychain, etc.).
