TXT is a DNS record, containing info in human-readable form for external sources to gain info about a particular domain or subdomain. In the most common situation, such a record is employed to prove that you own a domain name in case you are trying to add it to a search engine or to some web traffic analytics platform. Since only the Internet domain owner/administrator is able to add custom DNS records, the TXT record serves as a proof of ownership for the firm offering the service. Another popular use for this type of records is the e-mail SPF (Sender Policy Framework) security, that ensures that an email address will not be spoofed and that individuals will not get junk mail from allegedly your mailbox. The TXT record features details about the mail server where your electronic messages come from and serves as validation that it is a dependable one. As there are no regulations regarding the content of such a record, you could also include any other info as well.
