Right now it only supports Nostr Login via Nostr.band which is a nice login tool for Nostr you can just immediately plug in. You can use an extension, a signing app, or basically anything besides raw nsec (which is for your safety, bc I wouldn't trust it with your nsec yet probably! lol!)

I have my issues with signing extensions. Alby is the only one I know of with multi account support. I will jump ship as soon as a high quality alternative is available. Good on you. Never allow users to enter their nsec directly. 🔥

I can't use extensions on mobile and bunkers almost never work for me, they just hang. I wish more sites would support DM logins
