Additional context
Try to reproduce the problem with kitty --config NONE if you cannot then post a minimal kitty.conf that reproduces the problem. If the problem involves interaction with some other terminal program post a minimal config for that program to reproduce the problem as well.

yes, it's not supposed to. If you want to use a blank password, dont use
remote control password at all. If you want to use a password for a
particular action that is simple, use "a" or whatever. Once apassword is
involved, communication is encrypted, therefore, blank passwords cannot
be used.

that makes sense - i was trying that because it's referenced in the docs that i can use it https://sw.kovidgoyal.net/kitty/conf/#opt-kitty.remote_control_password:~:text=A%20set%20of%20actions%20to%20be%20allowed - this probably should be updated - happy to open a PR for this as well

If its documented it is probably intended to work in some situations, let me investigate in more detail when I have some time.
