A TXT record is text in free, human-readable form, which is 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 site to a search engine or to an analytics platform, which offers details about the web traffic to your Internet site. Setting up this sort of a record can serve as confirmation that you are the domain name owner and they will supply the content that you should include as the value when you create the record. Another application of a TXT record is to validate that an email message is sent by the domain owner and from a trusted web server - this is the so-called SPF security, which prevents any electronic address set up under your domain name to be forged and unauthorized people to send out spam making it appear like it was sent from your own mailbox. You could include any other info you want to be associated with your Internet domain in a TXT record as well.
