A TXT record, as the abbreviation implies, is a record, which holds information 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 example, have different ways of confirming that you're the owner of a given domain and one of them is actually by creating a TXT record with specific text that they provide and that you must use as the record value. The same verification method is used by some analytics platforms that monitor the traffic to your sites as well. Of course, in this situation the content of the record will be read by a robot, but it'll still be in human-readable form. A TXT record is also used in case you enable the so-called SPF protection for your email addresses so that you can prevent them from being forged. In this case, the record contains information showing that a given digital message is sent from a trusted and authorized mail server. You may use a TXT record for any sort of other information also, just like your company details, for example.
