Longer alpha-num lock-code
Ok, call me crazy/paranoid but why is the maximum length of the lock-code 10 numbers?
My normal (secure) passwords are around 20-30 characters and that's with letters, numbers and symbols.
If I would follow xkcd's proposal to use words it would be even longer.
At least when the KB TOH is out could you relax the lock-code restrictions?
(I would use partition encryption if it was available too)
