We available tools that can be used in resetting your password and regain access to your account. Let's first sort it out by following the steps below. Here's how:

2. Fill out the needed information. One of these is the license number. You can press F2 from the login window to see your license number.
3. The Name, Email Address, Phone Number, and ZIP code you originally used when you purchased the product. You can log in to CAMPS to find all these requirements.

5. Afterward, get the code from your email and enter it in book. It'll guide us through the process of creating the new password.
