To use a SQUARE ENIX Security Token, it has to first be registered online and attached to a SQUARE ENIX Account. The user who registers that SQUARE ENIX Security Token will be the only person able to use that SQUARE ENIX Security Token. Unless this registration is completed, the SQUARE ENIX Security Token will be unusable to access that account. Because of this design, a SQUARE ENIX Security Token cannot be used by a third-party.
