How to add Google login to your app without having private keys in your app or handing them to Google: https://viewsource.win/fiatjaf.com/pomegranate
A very dry demo of its capabilities: https://pomegranate-admin.netlify.app/
At its core it's a bunker powered by FROST threshold signatures. Supported now in https://nostrord.com/, https://jumble.social/ and https://hallway0.netlify.app, with others incoming.
If you already have NIP-46 bunker support this becomes very easy to implement, there is a step-by-step flow in the README there that even an LLM can follow.
