I still think all these password keys are the No. 1 reason why we don't have more people using crypto.  It would be great if we could use something like fingerprints, face recognition, voice recognition or anything where we don't have to rely on writing a big password down on paper.  The only way to be safe now is to have the master password written down in a few locations but then they all have to be 100% secure.  There has to be something better than that.
