Domain Lock, often referred to as Domain Update Lock, prevents your domain name from being updated or transferred without you first unlocking it from within your account.
Once your domain is registered and active in our system, you will see this setting available in your domain name settings screen (if domain locking is available for your domain name).
Domain Update Lock adds the following security features to your account:
Protects against DNS modifications, updating the auth code, and various other modifications. A domain name with this status lock is included in the zone files, can be transferred, deleted, and renewed.
Protects from unauthorized transfers out of our system to another Registrar. A domain name with this lock is included in the zone files, can be updated, deleted and renewed.
