A TXT record, as the abbreviation implies, is a record, that keeps data in human-readable form and not code. It could be created for a domain address or a subdomain for various purposes. Search engines like Google, for instance, have different ways of making sure you are the owner of a given domain and one of them is by creating a TXT record with certain text that they provide and that you will need to use as the record value. The exact same verification method is employed by some analytics platforms that check the traffic to your web sites as well. Needless to say, in this 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 furthermore used if you enable the so-called SPF protection for your email addresses so that you can protect them from being forged. In cases like this, the record contains info showing that a certain digital message is sent from a reliable and authorized mail server. You could use a TXT record for any sort of other information as well, such as your business details, for instance.
