cool! Is the auth private, or do I need to sign something with a whitelisted npub?
I'm working on it! https://sovereign.app/
We need auth in the cashu protocol, which we are working on now, to ensure only the people you want to use your mint can use it.

It’s open; anyone can sign up! The app also lets you create a new nostr profile if you want to test it with something not connected to your main nsec.
