Pasting into AWS DNS service from Google Workspace

To verify your domain with Google Workspace using AWS Route 53 DNS service, you'll need to add a TXT record. Here's how to do it:

1. Sign in to the AWS Management Console and open the Route 53 console.
2. In the navigation pane, choose "Hosted zones."
3. Select the hosted zone for your domain.
4. Choose "Create record."
5. For the record name, either leave it blank or enter the @ symbol. This represents the root domain.
6. For the record type, select "TXT" from the dropdown menu.
7. In the Value field, enter the entire verification string provided by Google, including the quotation marks: "google-site-verification=ycUl9IV0WpfgaxfJ9JsFcq-3E7W8-c7oW39npGvA8H8"
8. Leave the TTL (Time to Live) as default or adjust if needed.
9. Click "Create records" to save the new TXT record.

After adding the TXT record, it may take some time (usually a few minutes to a few hours) for the changes to propagate across the DNS system. Once propagated, you should be able to complete the verification process with Google Workspace.
