WCAG 3.3.7
Redundant Entry
Don't ask users to re-enter information they've already provided in the same process. Auto-populate or let them select previous values. New in WCAG 2.2. Helps users with cognitive and memory disabilities.
In plain terms
Don't make people type the same information twice in one process — remember it, or let them reuse what they already entered.
Why this matters
Re-typing the same details — an address, an email — within one process is tiring and error-prone, and a real barrier for people with cognitive, memory, or motor disabilities.
How to detect
Quick check
Walk through multi-step flows (checkout, sign-up). Are you ever asked to re-enter information you already gave? It should be auto-filled or offered as a 'same as above' option.
