The correct way to disable autocomplete in the browser for certain forms is to ….
-
Set autocomplete to “0”
-
Set autocomplete to “Off”
-
Set autocomplete to some other value
-
Set autocomplete to “no-store”
The correct HTML attribute value to disable autocomplete is autocomplete="Off". This prevents browsers from automatically filling form fields with previously entered data, which is important for sensitive fields like passwords or financial information.
Browsers historically respect the non-standard autocomplete="off" attribute on a form or input to prevent values (like passwords or sensitive fields) from being cached and auto-filled later. Setting it to an arbitrary or made-up value has no defined browser behavior and won't reliably suppress autocomplete, and no-store is a cache-control directive, not a valid autocomplete value.
