As available domain names become scarce, valuable domain names are becoming more expensive. Once a domain name has been stolen, it is difficult or impossible to retrieve it. As a registrant, you can take many anti-theft measures in advance.
Enable the security lock of a domain name registry
The security lock of domain name registries provides highest-level secure protection on domain names. It is a service provided by domain name registries at the root server level to protect domain names from being maliciously transferred, tampered with, or deleted. The security lock of domain name registries can be enabled for domain names with the following suffixes: .com, .cn, .net, .cc, .tv, .name, .中国 , and .gov.cn. After the security lock is enabled, the domain name can be set to one of the following states:
You must unlock your domain name before changing its state or information.

Enable the update prohibition lock
If the domain name registrar of your domain name is Alibaba Cloud, you can enable the update prohibition lock for free. Enabling the update prohibition lock prevents your domain registration information from being maliciously tampered with, such as the domain name contact, phone number, address, fax, and email address. The update prohibition lock can be enabled for domain names with the following suffixes: .com, .net, .org, .info, .biz, .mobi, .asia, .me, .so, .cc, .tv, .name, .tel, .cn, .中国, .公司, and .网络.

Provide authentic registrant information
When a dispute arises over the ownership of a domain name, the domain name administration determines the ownership based on the registrant information. Therefore, you must provide the authentic information of yourself or your enterprise when registering a domain name. If your domain name is stolen, you can provide corresponding materials to retrieve your domain name.
Update your email address and phone number
Ensure that the Alibaba Cloud account, email address, and mobile number for your domain name are authentic and valid. Update the information soon after you change or deactivate your email address or mobile number. For more information, see Modify domain name information.
Ensure that the email address that you offered is secure. We recommend that you set a strong email password that contains uppercase and lowercase letters, symbols, and numbers to improve password security.
