I am using Arch Linux. I currently have sshd set up with defaults so that a user can only login with my username/password. But I would like it to first prompt for a custom password that changes every time a user tries to connect. In other words, when somebody tries ssh me@mycomputer, it first asks for a custom password (for the sake of simplicity, let's say I want the password to be the date in yyyy-mm-dd-hh format). Then, whether or not the user typed in the correct password, I want it to ask for the login like normal. If both passwords are correct, access is granted. Otherwise, access is denied. I don't want the person logging in to have any indication of which password they got wrong. You should write your response with 800 or more words.
