Authentication agents helped solve the login sprawl of the past. But for modern systems, a unified API platform like Deck offers a more scalable, secure, and developer-friendly way to manage credentialed access.

Companies today face an ecosystem dominated by fragmented portals, legacy systems, and critical user workflows locked behind logins. APIs are rare, documentation is nonexistent, and interfaces change constantly.

Native integrations promise seamless connections between your product and the external systems your users depend on. Building them in-house looks straightforward until authentication breaks, portals redesign without warning, and your engineering team spends more time firefighting integrations than shipping features.

In today’s tech landscape, products that stand alone, lose. Customers expect seamless, connected experiences and integrations are what make that possible.

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.
