[1]stinerman writes "Three students at UC-Berkley used a 10 minute [2]recording of a keyboard to recover 96% of the characters typed during the session. The article details that their methods did not require a 'training text' in order to calibrate the conversion algorithm as has been used previously. The [3]research paper [PDF] notes that '90% of 5-character random passwords using only letters can be generated in fewer than 20 attempts by an adversary; 80% of 10-character passwords can be generated in fewer than 75 attempts.'"
