Are you talking about Hubpages or your own personal website. In case of HP, there is no need to verify. In case of your website, you have 2 options:
1. Open your index page in frontpage express > Right Click > Custom > Add > Now add "Verify" Under name and the value under "value"
2. Just save their HTML File with the file name they provide and then upload it onto your server. Now select Verify in "Webmasters Tool".
Similarly you can also verify your blogs and websites with Yahoo too.
PS: Verifying Blogs need some trick.
