In your blog post (https://www.w3.org/blog/2018/07/captcha-update/) you 
ask for feedback on Inaccessibility of CAPTCHA 

My comment is about the conclusion:
"While a majority of CAPTCHAs in use remain challenging for people with 
disabilities to complete, recent developments, including the Google 
reCAPTCHA, multi-device authentication, and the increased prevalence of 
Federated identity systems currently provide the most accessible and 
flexible options in separating humans from robots."

I cannot agree that Google ReCaptcha is an accessible option:
- as a screenreader user, it never accepts it when I check the check box 
"I am not a robot".
- Then I am presented with the visual verification method, which does 
not work for me as a blind user
- There is a link to an audio alternative that I can activate, but here 
is no accessible button to play the sound.
- there is an option to download the audio file but this does not work 
So I have found no way to pass the ReCaptcha.

Earlier in the text:
"Anecdotal evidence suggests that this CAPTCHA is currently the most 
accessible CAPTCHA solution and can be completed with a variety of 
assistive technologies. However, there is little formalized research 
investigating whether this is indeed the case."

In the mailing list accessible@googlegroups.com you can find many 
complaints about the inaccessibility of reCaptcha. So there is also 
anecdotal evidence that it does not work with several assistive 
technologies. That is why I would prefer not to mention ReCaptcha in the 
conclusion of this important document.

Kind regards
