Delete TXT record?

[eltonsaunders]

I believe the TXT record is only needed for verification and can be deleted once verification is complete. If that is accurate, it should be added to the article.

Thanks!

@eltonsaunders Thanks for the feedback! We are currently investigating and will update you shortly.

@eltonsaunders Thanks for asking question! No, you should not delete the TXT record. Actually, it’s recommended that you add it even if you already mapped a domain previously.

Adding domain verification IDs to your custom domain can prevent dangling DNS entries and help to avoid subdomain takeovers. For custom domains you previously configured without this verification ID, you should protect them from the same risk by adding the verification ID to your DNS record.

For more information on this common high-severity threat, see Subdomain takeover.

We will now close this issue. Let us know if have further query on this.
