Re: Next steps for accessible authentication

+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….
