A TXT record is text in free, human-readable form, that's associated with a domain name as a DNS record for one purpose or another. The most typical use of a TXT record is to add your site to a search engine or to an analytics platform, that offers info about the traffic to your website. Setting up this type of a record works as proof that you are the domain owner and they will provide the content you need to include as the value when you create the record. Another application of a TXT record is to verify that an e-mail message is sent by the domain name owner and from a trusted hosting server - this is the so-called SPF security, that prevents any electronic address created under your domain name to be forged and unauthorized individuals to send out spam making it appear like it was sent from your own mailbox. You could add any other info that you would like to be associated with your Internet domain in a TXT record as well.
