A TXT record, as the abbreviation indicates, is a record, that holds info in human-readable form and not code. It could be set up for a domain name or a subdomain for various purposes. Search engines, for example, have different ways of making sure that you're the owner of a particular domain and one of them is in fact by creating a TXT record with specific text that they provide and which you must use as the record value. The exact same verification method is used by some analytics platforms that check the traffic to your sites as well. Of course, in such a case 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 when you enable the so-called SPF protection for your email addresses in order to prevent them from being forged. In cases like this, the record contains data showing that a particular digital message is sent from a trusted and authorized mail server. You could use a TXT record for any sort of other information also, such as your company details, for example.
