What constitutes a good password? Since going Full Disk Encryption + Multi-Factor Authentication I’ve been thinking about different ways to secure passwords and auth. I tried biometrics, and only the finger print scanners work (which is what I now use). I also tried using the iSight with shape sensing, but that failed terribly. Voice activation also failed terribly. There are a number of apps out there that allow you to do a bit more of adaptive learning with passwords. One method I find interesting is switching to using pictorial representations to provide access in an adaptive manner. As such, here are the pictures one client has chosen (if only for me to easily find them when I need to log in to their servers):
