Again, I entered the wrong password! But how many times have I exchanged a password with another?
If someone had bad intentions he could collect all my wrong passwords, associate them with me and then access my confidential data somewhere else. If a person like that existed I would be forced to change my password often so that it’s password database is unusable as quickly as possible.
But someone like this doesn’t exist. Is it?
