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 web site to an online search engine or to an analytics platform, that offers info about the targeted traffic to your web site. Creating this sort of a record can serve as confirmation that you're the domain name owner and they'll provide the content that 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 trusted hosting server - this is the so-called SPF security, that helps prevent any electronic address created under your domain to be forged and unauthorized people to send spam making it look like it was sent from your own mailbox. You could include any other information which you want to be associated with your domain name in a TXT record as well.
