Paper Key

I have a Keybase account, it was created in 2019. I have full email, password, github link. I'm still logged in on the website, how can I log into the app if I lose my paper key?

I still use the old device when I first signed up for the app, it has software corrupt and I have to restore it.

The issue describes a Keybase account and app recovery situation but names no repository files, tests, or entry points. First determine whether the supported recovery behavior is documented; done would be a clear, accurate explanation of how to regain app access without the paper key, or a documented limitation.
