"I haven't finished logging in yet; IT changed my password to Tubular Bells."

I disagree with Bruce Schneier’s take on the new field of “implicit passwords” - passwords that you remember subconsciously rather than consciously and that you type in by, essentially, playing Guitar Hero.

He writes:

The system isn’t very realistic – people aren’t going to spend 45 minutes learning their passwords and a few minutes authenticating themselves…

Are you kidding? I would _totally_ use this just so I could log in to my PC with the hook from Back in Black.

On a more practical note, it’d make June-2009-oil-futures drunk-trading incidents a thing of the past. 

And you’d quickly learn never to get on the wrong side of the IT department, after the second or third incidence of them resetting your password to Never Gonna Give You Up.
