What this criterion requires
When an error is detected and correction suggestions are known, they are offered to the user (unless doing so undermines security).
Who it helps
Everyone who gets stuck on a failing form.
Example: fails vs passes
Error: "Invalid password."
Error: "Password must be at least 12 characters and include a number."
When you know what would fix the input, say it (unless it would leak security information).
How to meet and fix it
- Say how to fix it: "Password must be at least 12 characters", not "Invalid password"
- Suggest likely corrections ("Did you mean gmail.com?")
Common failures auditors find
- "Invalid input" with no guidance
