Redundant Entry
Information previously entered by or provided to the user that is required again in the same process must be auto-populated, available for the user to select, or made unnecessary.
What it requires
WCAG 2.2 SC 3.3.7 reduces the burden on cognitive-disability users by eliminating "type your address again" steps in checkout. If a user has entered their email at step 1, the email cannot be required again at step 2 unless re-entry is essential (e.g., for security).
Standard exceptions: passwords, security questions, and information whose accuracy must be re-confirmed (e.g., a verification step before payment). For everything else, auto-fill from the previous step or offer a "use the same as billing" toggle.
Common Shopify failure
Custom checkout extension that requires the customer to re-enter shipping address even after they entered it at the address step. Multi-step signup form that asks for first name on step 1 and again on step 3.
How to fix it
For native Shopify checkout, this is handled by Shopify's own forms. For custom storefront checkouts and signup flows, AccessComply's form-fix agent identifies redundant fields and either auto-populates or removes them.
