Keys, passwords and other details a person or an agent uses to get into a tool.
Credentials are never in the public folder and never in plain text, not even in the version control history. An agent only gets the access it needs for its task.
Example from Module 2
One folder for what may become public. Another for customer data, notes, credentials.
Module 2: “Protecting data: encapsulate and check”. In the Werkbank course room, with sign-in.
