Differences between PIN, au ID and au ID password
The PIN and au ID password are different things.

-
au ID: This is an ID provided by KDDI that allows you to use various services conveniently with only one ID.
-
au ID password: This is set by the customer when setting up of the smartphone for the first time.
It combines half-width alphanumeric characters (symbols are allowed) and it is set to more than 8 digits (e.g., 1234abcd).
