WCAG 2.2, or the Web Content Accessibility Guidelines 2.2, is a set of testable requirements for making websites and digital interfaces more usable for people with different abilities and assistive technologies. It covers practical issues such as keyboard access, focus visibility, target size, error handling, and predictable navigation.
In cyber security and digital service design, WCAG 2.2 matters because accessibility is often a reliability problem as much as a usability one. If a site cannot be operated without a mouse, if form errors are unclear, or if content breaks when users zoom or use a screen reader, legitimate users are blocked and risky workarounds appear. Teams use WCAG 2.2 as a concrete benchmark for testing and validation, especially in complex systems such as AI-driven portals, booking flows, and service catalogs, where a broken handoff can hide failures behind a polished interface.
