Learn how to find your account's serial number using Kotobee Author.
It's extremely important that you have your serial number stored with you somewhere secure. In case you lost it, you may retrieve it from Kotobee Author if it's used to log into your account. Simple follow the steps below.
Open Kotobee Author, and wait for it to validate your account. You can find that out from message at the top right corner.
If Kotobee Author does not show you your name, or shows "Enter serial number" instead, then you will need to retrieve the serial number from the email that was used in registration. Simply search for an email from email@example.com with subject "Your serial number". In case you don't find it, be sure to check your spam folders too.
Once it has successfully validated your account, it will display your user name.
Click on your name to open the user settings drop-down menu. Select Account Summary.
You will find your serial number listed in the account summary window as shown below.
