Once you've logged into BC, there are 2 ways to get to the Change Password page:

  • From the top-bar:

  • From the User menu:

Both will take you to the same page:

All you need to do here is enter the password that you're currently using into the first of the 3 fields, and then whatever you want to change the password to into the 2nd and 3rd fields.

Once you've done that, click on Change Password and you'll get a confirmation page from BC.
