Is it ok to remove Google TXT verification records after I've authorized my domain with Google? [closed]

Solution 1:

No, you shouldn't remove any of the verification files or DNS records. Google will periodically recheck your site and if it doesn't succeed you will lose access to WMT, for example. See this WMT support page:

Removing the record from your server can cause your site to become unverified, and you will need to go through the verification process again.

I'm not 100% sure but I think Bing will do the same. It makes sense because a domain owner or the roles of administrators might change and you don't want anyone who ever had access to your site's data to keep that access right forever.
