When you are on the website, you will see a login box in the upper right corner. If you hold your mouse cursor over it, you will see either two login boxes prompting you to enter your username and password or your name that identifies you as a member. If you look below this area, you will see Update Account to click on, which will allow you to change your email address and password once logged in.
Username changes can only be implemented by the C&B 24/7 team at this time. If you have a credit card change for a monthly account, you will need to cancel your C&B 24/7 subscription before your next renewal date, then reactivate your account with your new card information.
