It's basically a request for you to change your password. As far as I know, the DMM site will require you to perform a mandatory password change at least once in your account's lifetime, usually some time after you created your account.

The steps are pretty much like password resets for general online games — they'll send a password reset confirmation to your email, you click on the link and reset it.
