# Locking a domain to prevent unauthorized transfer to another registrar
<a name="domain-lock"></a>

The domain registries for all generic TLDs and many geographic TLDs let you lock a domain to prevent someone from transferring the domain to another registrar without your permission. To determine whether the registry for your domain lets you lock the domain, see [Domains that you can register with Amazon Route 53](registrar-tld-list.md). If locking is supported and you want to lock your domain, perform the following procedure. You can also use the procedure to disable the lock if you want to transfer a domain to another registrar.<a name="domain-lock-procedure"></a>

**To lock a domain to prevent unauthorized transfer to another registrar**

1. Sign in to the AWS Management Console and open the Route 53 console at [https://console.aws.amazon.com/route53/](https://console.aws.amazon.com/route53/).

1. In the navigation pane, choose **Registered Domains**.

1. Choose the name of the domain that you want to update.

1. On the **Details** section, in the **Actions** dropdown, choose **Turn on transfer lock** or **Turn off transfer lock**, depending on whether you want to turn the transfer lock on or off.

   You can navigate to the **Requests** page to see the progress of your request.
