A TXT record, as the abbreviation indicates, is a record, that contains data in human-readable form and not code. It could be set up for a domain address or a subdomain for a variety of purposes. Search engines, for instance, have different ways of making sure you're the owner of a particular domain and one of them is actually by creating a TXT record with unique text which they provide and that you should use as the record value. Exactly the same verification method is employed by some analytics platforms that keep track of the traffic to your sites as well. Of course, in this case the content of the record is going to 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 emails in order to prevent them from being forged. In cases like this, the record contains info showing that a particular electronic message is sent from a reliable and authorized mail server. You could use a TXT record for any kind of other information also, like your company details, for instance.
