I don't think Graham was claiming that his exact wording was the right
one. Finding the right wording, the right interface and symbolism and
methaphors for this is a task that would presumably involve designers
writers, and many others.

If one is just creating a key to be used with HTTP Signatures [1] 
then one may ask the user if he wishes to add a Key to his KeyChain.
If one is adding some form of credential, one may ask the user if he
wishes to add the signed statement by S that P. ( eg by the DMV that
you have a drivers licence ).

Then on reaching a resource that requires authentication the resource
can describe what types of credentials are needed for authentication.
The User Agent should then be able to present those credentials that
match and ask the user if he wishes to use it. The user may then also
want to set policies to automate this process.

Given how far User Interfaces have evolved in the past 30 years, from
the command line, to smart phones interacted with using gestures, it
seems that the argument that something cannot be done, is the one
where the burden proof lies on those that claim something to be impossible.
