nostr-login widget is a drop-in nip07 provider - you can add 1 line of code and users can sign in with extension, nsecbunker, signup locally, etc. might be a great temporary solution until you dive deeper and maybe build something custom https://github.com/nostrband/nostr-login/ 

 I tried it with my app but it didn't work 😭 

 Which one? How "didn't"? Could you please tell me more? 

 I tried both the npm package and the unpkg script in my react app, and I would get as far as the popup screen to enter a password, but then it just hangs
