Why do I need to create a new username and password?

The upgrade discontinued your current username and password, as well as your eServices preferences. To manage your account online, you'll have to create a new username and password once receiving your new printed and mailed BWL bill in June. Once registered and signed in, you'll be able to reset all your online account preferences, such as enrolling for eBilling and/or Autopay.
