Yes I am aware of that they can read the password (if not in memory). These friends are not very technical, and the purpose is that I use their device to fill in the complex password. It would take much longer if I were to spell it out, and its likely they would make typos. By handing me their device, its a sense of trust doing so. In return, I give internet access.
