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 another. The most common use of a TXT record is to add your website to an Internet search engine or to an analytics platform, which provides details about the traffic to your Internet site. Setting up this sort of a record serves as confirmation that you're the Internet domain owner and they'll provide the content that you ought to include as the value when you create the record. Another application of a TXT record is to verify that an email message is sent by the domain name owner and from a trusted web server - this is the so-called SPF security, which prevents any electronic address set up under your domain to be forged and unauthorized people to send spam making it appear like it was mailed from your own mailbox. You could add any other information you want to be associated with your domain address in a TXT record as well.
