Server Certificate Fingerprints



I’m trying to automate the process of creating Auth0 Identity Provider on AWS. That process involves me adding a Thumbprint. I’m trying to avoid writing bash scripts to query certificates via openssl. So i tried to create a couple of tenants in same region and checked the certificate thumbprints. It seems that they match, i mean every tenant within same region had same certificate thumbprint.

So my question is, is it a safe assumption? can i create a list of thumbprints and switch those depending on region? or thats just a coincidence and i should always query for certificate thumbprints using openssl?


Given that the thumbprints for certificates will change when they’re renewed, you’re better off not assuming it will stay.
