Problem: I want to remotely access my computer from untrusted computers like on friends house or at work.
Looking for: Remote desktop software (SSH is out of scope, as it could do commands in the background). Client should work in the browser or have portable binaries. Server should send some soft of 2FA before every connection without a way to remember it, so I could be safe in a case of a keylogger snooping on connection password. Not nessesary, but would be nice to have some sort of rate limiting for the inputs, so it won’t be possible for some rubber-ducky style script to open terminal and run command before I could react.
Malware attacking vulnerability in whatever third party software you end up using is far more likely. You can’t open a second tty with an existing SSH session, you’d have to authenticate again, which would require the 2FA. Using a GUI isn’t going to prevent “doing something very fast” and like I said you can rate limit ssh using nf/iptables if you think that’s helpful. I’m not sure what you are referring to when you say “terminal”, because that’s normally what is referred to as a tty.
