Locking and unlocking refers to the ability to transfer domains to different registrars. Unfortunately, there are many stories of people and companies losing their domain names due to inadvertent or even fraudulent transfers.
When a domain is locked, we will reject any request to transfer it to a different registrar. As part of our commitment to offer the most secure environment possible, all domains entering your account (via new registrations, transfers or account pushes) do so in the locked status. We also provide domain locking entirely free of charge with no limitations.
We recommend only unlocking your domains immediately before transferring to a different registrar... but why would you ever want to do that!
The following status will only be set when your domain is locked via your account:
The status of "clientTransferProhibited" is the registry status for a domain that cannot be transferred.
