That is why the key is something you KNOW, not something you HAVE. If
one can capture your password locally, then one can capture your key
However, keys are good to prevent brute-force attacks. Think of it
like a 256-character password using the entire ASCII field. Also, keys
are not susceptible to keyloggers.
