Each MY8 account is referenced by an 8 letter code - mine is SPOONMAN. Each MY8 account has a unique Hexagraph that represents the MY8 code. Similar to a QR Code or a Bar Code, the Hexagraph can be scanned by devices instead of typing in the code.

The Hexagraph for your account never changes, so you can use it wherever you like - documents, online, physically engraved or etched onto an item, or even tattooed on your body

Note that the circlular element in the top left corner of the Hexagraph signifies the correct orientation of the Hexagraph, and should always be in the top left corner.
