              Under certain circumstances, you might be forced to disclose a
              password. To keep your coins safe, BlueWallet can create another
              encrypted storage, with a different password. Under the pressure,
              you can disclose this password to a 3rd party. If entered in
              BlueWallet, it will unlock new 'fake' storage. This will seem
              legit to a 3rd party, but will secretly keep your main storage
              with coins safe.

              New storage will be fully functional, and you can store some
              minimum amounts there so it looks more believable.
