An auth code is like a key that you receive when you purchase a domain by auction or buy a domain.
You will need such an auth code to move domains e. g. to a new provider. If you win an auction at nicsell and we catch the domain successfully, you will receive the auth code by mail.With this you can go to your desired hosting service to deposit your domain on their server. Your provider might require further information from you.
It is also important that you move the domains in a timely manner, so that no additional costs come about. If domains remain untransferred on our servers for a long time, we might impose hosting costs on you.
This auth code method for .de domains exists since 2010 and the moving of a domain without an auth code is no longer valid.
An auth code for .de domains is valid for up to 30 days, but can be newly generated afterwards.
