Passwords are outdated, Patterns are the thing now (stef.be)

No. People have the same problems with patterns as with passwords. Patterns are even more predictable then passwords because a human is lazy and will create an 'easy' pattern.

This is just a cumbersome way to enter a numbers-only password, not a pattern. I can go from 9 to 1 without making an edge between the nodes and it will be translated as "91".
