Do you need to copy the bunker string to log in on another client? If so, does that mean you have to open this app to copy the bunker string?
Currently most apps expect a bunker string, so yes - you click Connect app in nsec.app and it shows the bunker url. If apps adopt nostr-login (or re-implement the OAuth-like flow themselves), users would just enter name@domain (@nsec.app or other nsecbunker domain) and get a popup to confirm the connection.
