I just mean that I will have to resetup my old node from passphrase backup, so that I can then try scanning in. I'm sure it was an old node that I no longer have setup.

For me it wasn't passphrases, I just scanned the SN login QR code with different wallets and clicked 'Authenticate'. Or maybe you're just describing the text version of that.

Dang man, I didn't even think of that. I know I accessed SN years ago, and I can see my old username if I look it up, but couldn't find anything in my emails. I bet I signed in with a lightning node. I have a book of old LND node passphrases that I'm going to try!
