"Three students at UC-Berkley used a 10 minute recording of a keyboard to recover 96% of the characters typed during the session. The research paper 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."
