Version: WCAG 2.2 and up
Number: 3.3.7
Level: A
Applicability:
  • Authentication Forms
Requirement:

For each step in an authentication process that relies on a cognitive function test, at least one other authentication method is available that does not rely on a cognitive function test, or a mechanism is available to assist the user in completing the cognitive function test.

Guidance:
Techniques: Techniques are not yet available for WCAG 2.2 success criteria.

Purpose

The purpose of this success criterion is to ensure that users with cognitive disabilities can authenticate themselves when cognitive function tests — such as password input, memorization, puzzle solving, and calculations — are used to prevent unauthorized access.

How to Meet

As it is not common for digital publications to authenticate users, this success criterion rarely applies.

If authors do attempt to use authentication forms with cognitive function tests to secure access to some part of a publication, they need to ensure at least one method that does not require the test or that there is a way to help users with the test.

For example, if a password must be entered, ensuring the user is not prevented from pasting in their password would be sufficient.

Additional Information

The knowledge base does not currently include information on accessible authentication due to the lack of implementation in publishing formats. Refer to the WCAG guidance documents for additional information.
