On average 2-3 errors. However the real thing we want to look at is what is my chance of guessing right across ALL characters. For 1 it's 95%, for 2 it's 90.2%, and it gets worse from there. The formula for accuracy would be .95^c where c is the number of characters in the password. So the chance of getting EVERY key correct in a 40 character password is < 13% and < 5% for 60 characters.
Right. The comment above is saying even if you are incorrect in 2-5 keystrokes it’s not hard to guess the correct keystrokes if you’re using a sentence style password.
You don’t need to guess every character.
What if the password is typed twice? You can easely figure it out then.
that's pretty high when you can use a computer to run the guesses
