Universal certificates
In the second half of 2023, Cloudflare started offboarding DigiCert as a certificate authority. This change does not affect existing Universal certificates, but will apply to new certificate orders and renewals.
The validity period for Universal certificates will also be decreased from one year to 90 days.
You do not need to make any updates to the Domain Control Validation (DCV) for your zone.
If your domain is using a Full setup, Cloudflare will automatically complete TXT-based DCV on your behalf.
If your domain is on a Partial setup, Cloudflare will automatically complete HTTP-based DCV on your behalf.
If you are currently pinning your Universal certificate, stop pinning the certificate. This will ensure your certificates are not impacted during the Universal certificate renewal.
If you have CAA records that are not automatically added by Cloudflare, make sure to allow the other Cloudflare CAs to issue certificates for your domain. Since Universal SSL does not guarantee which CA will issue the certificate, it is recommended that you add CAA records for all CAs that Cloudflare uses.
If you want to choose the issuing CA for your certificate, order an Advanced certificate. Once that certificate has deployed, disable Universal SSL to prevent Cloudflare from issuing the Universal certificate for you.
