Password Hints Can Be a Good Thing
As a general rule, I don’t like password hints. If the hint is any good, it would give an attacker additional info to crack your password.
However, I had that sinking feel of dread the other day after I rebuilt a MacBook Pro, attached the TimeMachine backup drive and was prompted for the password.
On the previous build of the computer, I must have entered the password, saved it to the keychain and forgot about it.
