Thanks ShiShi, this is the explanation I needed. I didn't really understand it with Samson's post. Ya the complexity part is what stops me from doing this and that I would have to remember to securely save 5 of these signatures somewhere safe. I guess if you wouldn't rely on a hardware wallet with a PIN to keep this pass phrases on them you could use something like seed signer to nuke your seed each time after use? I mean after you have saved them somewhere?
