ArsTechnica article on the next generation of security for our devices/lives, that finally does away with passwords.
Pro: Much easier for companies to secure products/data when you don't have to mess with passwords. Customers are finally released from needing dozens of different passwords everywhere.
Con: It's early. There's an oddity that it's not cross-OS, but that's a temporary glitch. And psychologically, humans have been trained to think of passwords as their lock/key, and may not feel so comfortable using their face/fingerprint everywhere for everything.
Bonus: This article is on ArsTechnica, so the comments section is very good. Serious discussion by serious people who know what they are talking about.
