Use the exact value for the intended service
Verification services usually provide a specific record name and token. Add the value at the correct DNS zone and preserve the supplied prefix or host label exactly. A token placed at the wrong name may be visible in DNS but still fail the service's check.
Different providers and purposes can require different prefixes. Do not copy a token from another product or reuse an old value unless the verification instructions explicitly allow it. If the domain's nameservers point elsewhere, publish the record with the provider that currently answers for the zone.
Confirm verification at the service
After the DNS record is published, return to the requesting service and run its verification check. DNS visibility alone does not mean the service has accepted the proof; the service performs its own lookup and decides whether the expected value is present.
Once verified, keep the record if the service requires ongoing proof, or remove it only when the provider's instructions say it is safe to do so. A TXT proof does not redirect traffic, attach a hosting project, or move mail. Those actions require their own domain and service configuration.
