Hi there,

New to this space of running my own domain sourced from metaname and using CF for my DNS. Both have 2FA enabled on the accounts.
A day or so ago, I received this email from CF titled "[Cloudflare]: Certificate Transparency Notification for optimalprime.nz" indicating that Sectigo had issued a certificate for my domain.

Issuer: CN=Sectigo ECC Domain Validation Secure Server CA,O=Sectigo Limited,L=Salford,ST=Greater Manchester,C=GB
Validity: 2023-01-26 00:00:00 UTC - 2024-01-26 23:59:59 UTC
DNS Names: *.optimalprime.nz, optimalprime.nz

Should I be concerned as I believe I have not done anything (I think) to trigger something like this.

Nothing to be concerned about. Just Cloudflare telling you a certificate was generated for your domain. Dependent on the SSL settings you have defined for the domain on Cloudflare.

You’ll get a whole lot of those emails if you’re on Cloudflares free account using their SSL certificate as the certs are across a whole lot of domains.

I’d recommend turning it off. No need on small accounts.

Yep, just Cloudflare obtaining SSL certs for your domain.

It should also say at the bottom of the email:

Note that Cloudflare is now issuing backup certificates through Google Trust Services and Sectigo. Read more at https://developers.cloudflare.com/ssl/edge-certificates/backup-certificates/.

Thank you all for the feedback and guidance. Yes, CF account is free plan.

Will look at my CF account settings and will compare with another domain I have setup under the same account which I use for email following GZ advice to ditch ISP email.
