TXT is a DNS record, that contains info in human-readable form for external sources to get info about a specific domain name or subdomain. In the most common situation, this sort of record is employed to prove that you own a domain if you are trying to add it to an Internet search engine or to some traffic analytics platform. Considering that only the domain owner/administrator can add custom DNS records, the TXT record works as a proof of ownership for the corporation providing the service. Another popular use for this type of records is the email SPF (Sender Policy Framework) security, that helps to ensure that an e-mail address isn’t spoofed and that others will not get unsolicited mail from allegedly your mailbox. The TXT record features details about the mail server where your electronic messages arrive from and functions as proof that it is a reliable one. Since there are no rules about the content of such a record, you can include any other information also.
