Does Mullvad allow me to connect using wireguard without pasting my private key into their website? Their website says the private key never leaves my browser and is only used to generate the configuration file, but all I really want to do is give them a public key and I suppose let them know which server I'll be connecting to. I can put together the config file by hand myself, thanks, I shouldn't need to ever copy the private key into my clipboard, let alone paste it into a browser.
