Verify your domain with a DNS TXT record
Add a TXT verification record (any domain host)
- For the record type, select TXT.
- In the Name/Host/Alias field, enter @ or leave it blank.
Your host might require you to enter your domain, which looks like yourdomain.com, into this field. Your other DNS records might indicate what you should enter. - In the Time to Live (TTL) field, enter 86400 or leave the default.
- In the Value/Answer/Destination field, paste the verification record you copied in step 1.
- Save the record.
Note: If you see a warning message about changing your DNS settings, disregard it. Adding the TXT record won’t damage your website or DNS settings.
