No Easy Answers
Attacks, breaches, keyloggers -- it's pretty easy these days for just about anyone to get access to passwords, whether one at a time or by the handful. Despite this, passwords remain the ubiquitous method for online security.
Why? Well, in part, because it's a huge challenge to find the right balance between security and usability. Make it too difficult for users and we put up unreasonable obstacles; make it too easy and we're left vulnerable to attacks.
