For Review: Updated Inaccessibility of CAPTCHA

Dear WAI Interest Group,

W3C WAI invites you to comment on the updated Working Draft of:
      Inaccessibility of CAPTCHA
https://www.w3.org/TR/turingtest/

Overview:
The document examines a number of approaches that allow systems to test 
for human users, and the extent to which these approaches adequately 
accommodate people with disabilities. The document looks at 
cryptographic authentication to verify the user is human, via W3C 
technologies that remove the need for interactive CAPTCHAs.

Updates:
This document was previously published as a W3C Working Group Note. With 
the recent updates, it is now a 'First Public Working Draft'

In-progress updates to the document are available in the Editors' Draft at:
https://w3c.github.io/apa/captcha-accessibility/

For review:
We particularly would like your comments on:

  * The use of W3C technologies to remove the need for interactive CAPTCHAs
  * The use of Turing Tokens
  * Information about recent alternatives to the use of CAPTCHA challenges.
  * Comments concerning the discussion in the document of barriers that
    CAPTCHA creates for people with disabilities.

Comments:
To comment, please open a new issue in the APA GitHub repository:

Please create separate GitHub issues for each topic, rather than
