1.3.5 Identify Input Purpose
The purpose of input fields collecting user information can be programmatically determined.
Why it matters
Cognitive impairment
For users with memory or attention difficulties, autofill dramatically reduces input errors and effort.
Motor impairment
Users who find typing difficult can minimize input with autofill.
Multilingual support
When the input purpose is clear, the browser can automatically add icons or labels, overcoming language barriers.
Useful for everyone
Proper autocomplete shortens input time for all users and can lower drop-off rates.
Live demo
Support for autocomplete
No autocomplete
Without autocomplete, the browser cannot tell what each field is for, so helpful autofill support does not work.
Understand through a persona
