            Hi Gregg Someone like me, who has a very week if any visual memory, can not often copy information accurately. I leave it to you to decide if that makes me very seriously cognitively disabled ;)Clearly I can however use all the solutions mentioned. All the bestLisa SeemanLinkedIn, Twitter---- On Mon, 19 Jun 2017 22:57:52 +0300  Gregg C Vanderheiden<greggvan@umd.edu> wrote ----Sorry I wasn’t asking if people with cognitive disabilities had been asked.  — I was asking Were people with cognitive disabilities     that are severe enough that they cannot copy information,    tested with each of these techniques and were they able to do each of them.   If not then they are not alternatives for them.If people can copy information then they don’t need these This is a pretty severe cognitive disability — and it looked to me - from my work with people with cognitive disabilities,  like anyone who was unable to copy information would be unable to do many or all of these.     I am delighted to be proven wrong.    Has someone demonstrated that these are doable by the group this is targeted to?  (people who cannot even copy information) thanks   g Gregg C Vanderheidengreggvan@umd.edu   On Jun 19, 2017, at 2:56 PM, lisa.seeman <lisa.seeman@zoho.com> wrote:Hi GreggYes, they have been reviewed by security experts and people with cognitive disabilities.We are also reaching out to the web authentication group to see if they have any issue wit the current draftAll the bestLisa SeemanLinkedIn, Twitter---- On Mon, 19 Jun 2017 21:23:18 +0300 Gregg C Vanderheiden<greggvan@umd.edu> wrote ---- +1 to Jason’s concern about security of these.  Have they been vetted by a security specialist? Also — are these supposed to be easier than copying something ? All of these appear to be cognitively much more complicated than copying information from one place into the field.   As such - is this something where the solution requires more cognitive skills than the problem? Has anyone demonstrated that someone who cannot copy information — can do any/all of these?     That these are indeed simpler? If not - then is there any grounds for assuming that any of these will reduce the cognitive demands on a person…..These all sound complicated to me…. g Gregg C Vanderheidengreggvan@umd.edu   On Jun 19, 2017, at 1:48 PM, White, Jason J <jjwhite@ets.org> wrote:  From: lisa.seeman [mailto:lisa.seeman@zoho.com] Sent: Monday, June 19, 2017 1:30 PMWe are allowing multiple alternatives, such as: two step authentication that has a link to press as an alternative to entering a code[Jason] What are the security implications, if any?
