@scott No data backup, no identity backup. All your data clone servers are dead, all you have left is an identity provider that’s still live.

You establish your control over that identity via any challenge-response framework.

Now you can “claim” your profile on any live data service. Even one where you hadn’t previously cloned to.

Taking a step back: imagine if there were no data services, and all data was transferred out-of-band. How do you claim ownership of a billboard message?
