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 widespread use of a TXT record is to add your website to a search engine or to an analytics platform, that offers information about the targeted traffic to your site. Setting up this kind of a record can serve as confirmation that you're the Internet domain owner and they'll provide the content you need to include as the value when you set up the record. Another purpose of a TXT record is to validate that an e-mail message is sent by the Internet domain owner and from a reliable server - this is the so-called SPF security, that helps prevent any electronic address set up under your domain name to be forged and unauthorized individuals to send spam making it appear like it was mailed from your own mailbox. You may include any other info which you want to be associated with your Internet domain in a TXT record as well.
