「引き継ぎパスワード」is what they call the transfer password. You know, when you want to transfer from one device to another, you go to the settings and issue that password? In the same settings pages as the timing and idol image cut-ins and sparkly effects.

It's telling you to tell them when was the last time you requested such a password. Or if you didn't ever transfer devices before, just tell them so.
