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 widespread use of a TXT record is to add your site to an Internet search engine or to an analytics platform, which provides info about the targeted traffic to your website. Setting up this type of a record serves as confirmation that you are the domain name owner and they will provide the content that you ought to include as the value when you create the record. Another application of a TXT record is to confirm that an e-mail message is sent by the domain address owner and from a trusted web server - this is the so-called SPF protection, which prevents any electronic address set up under your domain to be forged and unauthorized people 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 domain in a TXT record as well.
