• Seems awfully idealistic to me. I wonder how long it will take to establish a good baseline. What if I reformat my phone or buy a new phone. What if I have no connection. I'd imagine some of the times that you would NEED your phone the most would be when you're not doing what you normally do. I'd imagine they'll still let you just enter a password as a fail-safe, but then what is the point? You still have the vulnerability of a password with the additional overhead and tracking of constant monitoring. I hope it works out though because Id really like to see passwords become a thing of the past.
