edge case: unregister + re-register with 2+ devices #36

  1. have a flock sync account on 2 or more devices (lets say A, B and C).
  2. unregister and then quickly re-register the username with same password using device A.
  3. device B and C will be able to login but everything will be encrypted a new set of keys.

Devices B and C still have the valid master passphrase so they could import the new key material from the remote key collection or simply wipe their Flock install clean and start fresh.

Not an edge case I expect we'll run into often but should be addressed.
