Control Account Name and add 'Change Password' on Logon

Hi, I have a Security requirement to provide users of my Website a specific Username and Password prior to logging onto the Website. When the user uses those credentails they should be prompted to change the password to something new.

The flow should be something like this:

  1. User receives Username and Password
  2. User logs onto the Website and is prompted to Change password
  3. After changing the password they are redirected to a one time Terms of Use page
  4. Once accepted they are redirected to the member pages

How do I do this in Wix ?
