If you need to change your verification method (for instance, if you have changed your content management system to one that doesn't support your current method), you can change it by following these steps:
Change verification method:
- On the Webmaster Tools home page, click the site you want.
- On the Dashboard, click Configuration, and then click Users.
- Click Manage site owners, and then click Verify using a different method.
- Verify your site again using the new method.
