Transfer lock

What it checks

Whether the registry shows the domain locked against transfer (clientTransferProhibited), for generic TLDs such as .com, whose registries all keep the status.

Why it matters

The lock stops the domain being moved to another registrar without you, one of the ways domains are stolen.

How to fix it

1. Turn on the transfer lock, sometimes called registrar lock, at your registrar.
2. Turn it off only while you move the domain yourself.
