Oddbean new post about login | logout Maybe because I have used up my nostr.build free privileges? Just tried making a new account, and I just get a spinning "connecting, establishing connection to your key storage" notification.
I'm not aware of a total limit for free accounts. You need to accept the nsec.app connection request. If you're on iOS, there's special instructions https://nsec.app/ios.html. It's much easier to use a nip-07 extension though. I use @nostore on iOS.
No limits for free usage, just the file size.
