A TXT record is text in free, human-readable form, that's associated with a domain as a DNS record for one purpose or other. The most popular use of a TXT record is to add your site to an online search engine or to an analytics platform, that provides details about the web traffic to your site. Setting up such a record serves as confirmation that you're the Internet domain owner and they will supply the content you should 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 reliable web 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 spam making it appear like it was sent from your own mailbox. You can include any other info that you would like to be associated with your Internet domain in a TXT record as well.
