Verify your domain (host-specific steps)
Before you can use your domain with your Google service (for example, Google Workspace or Cloud Identity), you need to verify that you own it. Your domain is your web address, as in your-company.com. Verifying your domain prevents anyone else from using it with your Google service.
If you’re not sure who your host is, see Identify your domain host.
