Technique F107:Failure of Success Criterion 1.3.5 due to incorrect autocomplete attribute values

About this Technique

This technique relates to 1.3.5: Identify Input Purpose (Failure).

This failure applies to form inputs created in HTML which collect information about the user of the form.


The purpose of this technique is to identify a failure condition where form inputs do not have the correct autocomplete attribute values for inputs that request information about the user of the form.

Success Criterion 1.3.5 uses a fixed list of tokens in Input Purposes for user interface components (based on the HTML 5.2 autocomplete attribute's fixed list of token values) because the programmatic association of specified token values (metadata) allows for other machine processing, such as expressing the input label in different modalities.

Another important part of this Success Criterion is that the token values are associated with inputs that are scoped directly to the primary end user.


Example 1: Incorrect attribute

An online form used to collect the user's name and birthday which uses incorrect autocomplete attributes. The correct attribute value for the first control is name, and for the second control the made-up attribute value birthday was used instead of bday.

<h2>Your details:</h2>
<label for="uname">Name:</label>
<input autocomplete="email" id="uname" type="text"> 
<label for="ubirthday">Birthday:</label>
<input autocomplete="birthday" id="ubirthday" type="text">

For each form field which collects information about the user of the form:

  1. Check that the form field has an autocomplete attribute and value pair that does not match the purpose of the input.
  2. Check that the input purpose is not communicated programmatically through any other method.

Expected Results

  • If checks 1 and 2 are true, then the failure condition applies, and the content fails the Success Criterion.
