Verifying Passwords By the Way They're Typed
Zothecula writes "There are good passwords and bad passwords, but none of them are totally secure. Researchers at the American University of Beirut, Lebanon, are working on strengthening an approach to password security that's not just about what you type, but how you type it (abstract)." Note that the actual paper appears to be behind some crappy paywall: hopefully the research exists elsewhere on-line.
It doesn't. My bank used such a service for a while before it stopped due to complaints. If you made a mistake, paused, etc you would need to start over. Backspace automatically did it for you. It was a major PITA when my wife would log in to our bank account, then I would try. It always seemed to remember her slow typing but not mine. Plus, it would reject me if I used the number pad to enter the account number because digits there were different keys apparently then the digits on the top row.
