But this got me thinking, what if I'd just continued with the Wallet ID that wasn't mine?
Since the next step was to create a new Passphrase, could I have just done this and got access to whoever's wallet I mistakenly now have the root key for?
You can't consider that it's someone else's wallet just because it's valid.
The root key and Wallet ID aren't something that's pulled-out from a server during backup and crossed-checked during restoration.
The displayed "
someone else's" Wallet ID was just based from the wrong (
but valid) Root Key that you've entered.
Restoring someone else's wallet using a random root key would require far greater luck than winning the national lottery jackpot 1000+ times in a row.
