The Registration Process: When you first purchase or renew a G DATA license, you receive a Registration Number (a.k.a.: Serial Number or License Key).
Your license is inactive (and does not expire!) until you use this Registration Number to activate any of your G DATA products.
This step is called the Registration Process.
After it, you will receive a set of Login Credentials (User Name and Password) via email and you will need to use those to activate the program on any additional computers if you have a multi-PC license, or to reactivate the program in case of a re-installation on the same PC.
In summary: you only need to use your Registration Number once to activate the license after a purchase or renewal and from then on you will need to use your User Name and Password for any additional activation.
