A TXT record, as the abbreviation indicates, is a record, which contains info in human-readable form and not code. It may be set up for a domain or a subdomain for many different purposes. Search engines like Yahoo, for instance, have different ways of confirming that you are the owner of a given domain and one of them is in fact by creating a TXT record with certain text which they provide and that you need to use as the record value. The exact same verification method is employed by some analytics platforms that check the traffic to your Internet sites as well. However, in this case the content of the record is going to be read by a robot, but it will still be in human-readable form. A TXT record is also used if you activated the so-called SPF protection for your email addresses in order to protect them from being forged. In such a case, the record contains info showing that a given digital message is sent from a trusted and authorized mail server. You could use a TXT record for any other information also, just like your business details, for example.
