lets say for arguments sake, i had hypothetically booted up a live CD of Tails on a junk laptop with no hard drive, created a throwaway account on SR 2.0, transferred some bitcoins from blockchain using shared send, let the computer verify the transactions and got busy doing something else, came back an hour later and accidentally hit the power button on junk laptop, live cd shuts down, i forget username to SR 2.0. hypothetically what would be the best way short of remembering my exact username to recover said account name if i know the password, pin, items in my cart, and amount of BTC that should be in my wallet?
You are screwed :) (hypothetically of course)
