I tried building an easy to use a password manager for the normie market 8 years ago.
One of the biggest problems I had was how I might easily backup and sync their passwords across devices without trusting me, a single point of failure. Never figured it out.
When I learned about nostr this was the first non-social media use case that came to mind. So glad to see someone run with it!
