First, the cat will ask you for a password. If you have one, enter it, if you don't, enter something random. After that, set a variable to whatever you want. You can a link a password to that variable by setting a password after. Now, click on the flag again.The cat will ask for a password and if you type in what you set the password for, the variable will change to what you set it to before.
Note that the passwords will reset after a page refresh and the passwords will not save on different accounts. If you can seem to fix this, please remix and I will look into it.
