I have a domain that is set-up with Google Business Apps for email under one Google account, and I verified the domain using a google-site-verification TXT record. BUT, I've just added it to my Webmaster Tools which is under a different Google account, and added a second google-site-verification txt record along side the existing one, as it didn't detect the first TXT record.
Is this safe to do? It has verified ok, but I'm just wondering if it will break.
