A feedback:
The login screen shows a “nsec / user@nsec.app” suggestion, but it can actually be used with any bunker url; I would highlight this.
Then I think that the main options should be Nostr Connect and the extension, I would move the "danger" nsec option below, with a proper disclaimer.
You should also hide the extension button if it is not present (and maybe show a box that explain why and how the user should install it), currently it just fires an error in console without any visible feedback.
