It doesn't negate, innately, that the action is literally compelling the defendant to incriminate himself with his own actions/words, not his bio-metrics. If the crux is literally that his compulsion is moot to the establishment of the evidence, then it both begs the question you had mentioned - why is it needed - and raises the obvious comparison of a murderer who has confessed to his crimes being compelled to divulge the location of a body. In that comparative example, the location could contain more incriminating evidence. So I guess make your passwords incriminating or make sure you have multiple domains/spans of crimes all unrelated in the same virtual place.
