When your domain is locked, you'll be substantially protected from unauthorized third parties who might try to misdirect your name servers or transfer your domain without your permission. You will also be unable to inadvertently make changes to your name servers that could prevent Yahoo! from hosting your domain services properly. In the Advanced DNS section of your Domain Control Panel, you will see that the option to change your name servers has been disabled; you, the plan owner, will need to unlock your domain before your name servers can be modified.

When your domain is unlocked, you will be able to modify your name servers, and third parties may be able to initiate a registrar transfer for your domain. We recommend turning locking off only in the event that you need to make changes to your domain name servers. Learn how to unlock your domain.
