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 other. The most typical use of a TXT record is to add your website to an Internet search engine or to an analytics platform, that provides info about the web traffic to your web site. Setting up this type of a record serves as verification that you're the domain owner and they'll supply the content you should include as the value when you set up the record. Another purpose of a TXT record is to confirm that an email message is sent by the domain name owner and from a reliable server - this is the so-called SPF protection, which prevents any electronic address set up 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 information that you'd like to be associated with your domain address in a TXT record as well.
