Here’s how it’s done:
1. On the Webmaster Tools home page, click Manage site for the site you’d like to verify, then select Verify this site . If you haven’t added the site yet, you can click the Add a site button in the top right corner.
To do this, you must have "View, Edit, and Manage"
account level permissions
in Google Tag Manager.
2. On the Verification page, select
Google Tag Manager
as the verification method and follow the steps on your screen.
And you’re done!
