AEM Forms autocomplete problem

We’re facing an issue with browser autocomplete behavior on a public web form and it’s starting to generate incorrect submissions.

we have a standard “First name” and “Last name” form section. Recently, in Google Chrome (we cannot identify the browser and version ) , the browser’s autofill feature started filling both the “First name” and “Last name” fields with the user’s first name only. Users often don’t notice this, so they submit the form with an incorrect last name (it’s just their first name duplicated). This creates data quality issues.

Is there any way to force the browser autocomplete behavior? 

 

Thanks

​@Nidihsa  You cannot reliably force a browser to populate a particular value or to honor autocomplete="off". The browser owns the autofill behavior.

AEM Forms can, however, provide the correct semantic hints:

  • First name: given-name
  • Last name: family-name
  • Full name: name

 

If the priority is data quality rather than autofill

Do not depend on browser autofill settings as the data-quality control. Add validation in both places:

Client-side validation

Display a warning or validation error when:

normalized(firstName) == normalized(lastName)

For example:

Please verify that your first name and last name are different.

Do not reject every equal pair automatically. Some users may legitimately have a single name or identical name parts, depending on the business and regional requirements.

Server-side validation

Repeat the validation after submission. Client-side validation can be bypassed and should not be the only protection for submitted data.

A stronger design is to add a final review step showing:

First name: {{firstName}}
Last name: {{lastName}}

Require the user to confirm the displayed values before the final submission.

Can you disable autofill?

You can request that browsers do not autofill the form:

<form autocomplete="off">
  <input autocomplete="off">
  <input autocomplete="off">
</form>

However, this is still not a universal enforcement mechanism. Browsers and password managers may override or interpret the setting differently, particularly for fields they identify as names, addresses, credentials, or payment data.

Therefore:

  • Use correct semantic tokens when autofill is desirable.
  • Use autocomplete="off" as a mitigation when autofill is causing unacceptable risk.
  • Still validate the submitted values server-side.
  • Do not use randomized field names or misleading tokens as a workaround; that can damage accessibility, integrations, and future browser behavior.
