Whether you're triggering a read job from a payroll provider or pushing a payment to a utility portal, every action starts with trust: who the user is, and what they’re allowed to do.In this article, we’ll take you behind the scenes of Deck’s authentication system, how it works, how it scales, and what developers need to know to integrate it cleanly into their product.
