We're not great at choosing and remembering secure passwords, admit it?!
While my wordly combinations of aussie slang / l33t are contributing (marginally) to making my online life more secure ;) - I've been embarrassingly compromised more than once. Thus I would give anything for an easy way to meet the ridiculous password requirements and not get tripped up by my nonsensical security answers!
Enter the grid solution! I've seen this in commercial enterprise, but this example is a free, low-tech password vault.
There are some people drawbacks; starting at corner/edges, reusing passwords. However, assuming you're the kind of person who chooses this solution, let's assume you'd avoid this ;)
If you turn the solution about, and start challenging with grid co-ordinates, you're coming close to infringing on patented 2nd-factor authentication from Entrust. Although if you go down that road, why don't we start challenging with connect-the-dots, next item in the series, etc ;D
In personal news, I discovered the game NETHACK! today.
