Azure Front Door Standard and Premium support Bring Your Own Certificates (BYOC) based domain ownership validation. Azure Front Door automatically approves the domain ownership if the Certificate Name (CN) or Subject Alternative Name (SAN) of the provided certificate matches the custom domain and the certificate is valid. This feature reduces the steps and efforts required to prove the domain ownership and makes the Dev-Ops experience more streamlined.
If you choose to use Azure Front Door managed certificate, the domain ownership will continue to be validated via the DNS TXT record.
For custom domains created before this feature is supported and the domain validation status is not approved yet, you need to trigger the auto approval of the domain ownership validation manually. For more details, please refer to Configure custom domain on Azure Front Door.
