I'm interested in finding out what is the best method to enter sensitive information somewhere given an insecure computer.
Granted, I know that if the computer has a keylogger or some other malware that captures input, there are much more important things that I should worry about (for example what I am searching up on google, don't want those pesky hackers to know that I'm looking up cute dog photos).
But what if I am logging in on a school computer that has something like LanSchool so that instructors may monitor our computer activity? What if I am visiting an Internet/cyber café?
I have heard that on-screen keyboards (such as the one given by lastpass) will bypass keyloggers. But I'm paranoid, an attacker might use my cursor position every time I click to deduce what key I press.
Given that I have a keylogger, what are effective ways I can use to input sensitive information on say, a web form or a client app?
(Note: please avoid answering "do not use that computer" because I already know that if I want to avoid compromising my information, I should not use a compromised computer)
