Sign on with Nostr would work too
Discussion
The problem is some apps (primal comes to mind first) only provide “sign with nsec” option. Web interfaces allow login with extension, but as soon as you save them on your desktop (as a PWA), you can’t login with extension any more.
Oh, I see what you mean now. Anyone integrated this already? I think there was a list of which clients support which NIPs. Can’t find it 😣
