TXT is a DNS record, which contains info in human-readable form for external sources to obtain information about a specific domain or subdomain. In the most common situation, such a record is used to prove that you own a domain if you're trying to add it to an online search engine or to some site traffic analytics platform. Due to the fact that only the domain owner/administrator can add custom DNS records, the TXT record serves as a proof of ownership for the company offering the service. Another popular use for this type of records is the email SPF (Sender Policy Framework) security, which ensures that an email address shall not be spoofed and that others will not receive unsolicited mail from allegedly your mailbox. The TXT record features details about the mail server where your electronic messages arrive from and serves as validation that it's a reliable one. Because there are no regulations about the content of this sort of a record, you could also include any other information also.
