TXT is a DNS record, containing info in human-readable form for external sources to get info about a particular Internet domain or subdomain. In the most common situation, this type of record is employed to prove that you own a domain name if you are trying to add it to an Internet search engine or to some website traffic analytics platform. Since just the domain name owner/administrator is able to add custom DNS records, the TXT record works as a proof of ownership for the company supplying the service. Another popular use for this sort of records is the email SPF (Sender Policy Framework) security, that makes sure that an email address won't be spoofed and that individuals will not get junk e-mail from allegedly your mailbox. The TXT record features information about the mail server where your digital messages arrive from and functions as confirmation that it's a trusted one. Because there are no rules about the content of this sort of a record, you can add any other info also.
