technique to include security

Hi 
I was thinking of the following technique as a way to include security and other considerations






"Do not require cognitive abilities when it is  avoidable"


In security this may include:
Requiring that the user has a good working memory or short term memory required to copy a code
Requiring that the user can remember complex passwords
Requiring that the user can remeber spelling of terms used in security questions such as how to spell a strange pets name
Requiring that the user can remember visual patterns


Having tokans, signing in via email account or face book, or biometrics are all alternatives to the above




In voice  systems this may include,
Requiring the user to understand categories,
Requiring the user to remember numbers
can all be used as a barrier to getting human help

is is aviodable by having 0 as a reserved digit to access a human


In the Web of things this may include:
remembering what symbols mean
remembering sequences to run certain tasks

This is aviodable by having simple text with symbols and 
clear discovrability of how o complete each task
and recovrability from errors





All the best
