TXT is a DNS record, that contains info in human-readable form for external sources to gain info about a certain domain or subdomain. In the most common scenario, this kind of 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 website traffic analytics platform. Due to the fact that only the domain address owner/administrator is able to add custom DNS records, the TXT record functions as a verification of ownership for the business supplying the service. Another popular use for this kind of records is the e mail SPF (Sender Policy Framework) security, which ensures that an email address isn’t spoofed and that individuals will not get junk e-mail from allegedly your mailbox. The TXT record includes information about the mail server where your online messages arrive from and serves as verification that it's a trusted one. Because there are no rules concerning the content of this sort of a record, you can add any other info also.
