Two new account types are able to be linked under your External Accounts settings. Google Webmaster Tools CloudFlare For now, it's just used as two additional options for verifying ownership of domains for whatever reason (for branding free licenses, selling in an area that requires domain ownership verification, etc.). Long story short is if you have already verified your domains through Google Webmaster Tools or CloudFlare, you don't have to bother with adding DNS records or uploading a file to verify domain ownership any longer (you can still do it that way of course if you want).
I am glad to hear that. It will surely cut lots of threads asking on how to verify domain using file verification. It always better to have one central location to verify domains/sites (such as Google WebMasterTools). I couldn't remember how many tags/files verification present on my domains at the moment. Out of curiosity, Is there any trophy points for linked two account listed above? I am just kidding BTW.
I'd Love To, But there is no Update Link or Create Link menu. The form is available once the page loaded without pressing Create Link just like other category when I tried to link another external accounts. There is no menu or button either after I enter my details. Is it browser specific? Or maybe I have something in my browser which stop it to work properly? I have refresh it multiple times and there is still no menu or button after I enter my details. Hmm, I think I would not going to get an extra Trophy Points. More info: There is no problem when I tried to link my Google Webmaster Tools account. It was done almost instantly. Further testing show an error. When I tried to remove the link this pop up appear:
Should have a Save button at the bottom. CloudFlare works a little different, it's not supposed to have a Link/Unlink button... you just put the info in or remove it for that one. Unlinking Webmaster Tools account should work now.
