Everything is more fun with a friend! We've just added a feature to Webmaster Tools Site Verification to make it easier to share verified ownership of your websites.
In the past, if more than one person needed to be a verified owner of a website, they each had to go through the meta tag or HTML file verification process. That works fine for some situations, but for others it can be challenging. For example, what if you have twenty people who need to be verified owners of your site? Adding twenty meta tags or HTML files could be pretty time consuming. Our new verification delegation feature makes adding new verified owners a snap.
Once you're a verified owner of a website, you can view the Verification Details page (linked from Webmaster Tools or the Verification home page). That page will show you information about the site as well as a list of any other verified owners. At the bottom of the list of owners, you'll now see a button labeled "Add a user...". Click that, enter the user's email address, and that person will instantly become a verified owner for the site! You can remove that ownership at any time by clicking the "Unverify" link next to the person's email address on the Details page.
There are a few important things to keep in mind as you use this feature. First, each site must always have at least one owner who has verified directly (via meta tag or HTML file). If all of the directly verified owners become unverified, the delegated owners may also become unverified. Second, you can only delegate ownership to people with Google Accounts. Finally, remember that anyone you delegate ownership to will have exactly the same access you have. They can delegate to more people, submit URL Removal requests and manage Sitelinks in Webmaster Tools, etc. Only delegate ownership to people you trust!
We hope this makes things a little easier for those of you who need more than one person to be a verified owner of your site. As always, please visit the Webmaster Help Forum if you have any questions.
