Is a subscription key considered a secret?

Feb 16, 2024
We automatically set up our Proxmox nodes using ansible and need to store the subscription keys somewhere (in our source repository, in the filesystem, etc.)

Now the question arose whether a subscription key is something that can be stored in plaintext or if it should considered as a secret (like a password or a private key).

What is the "official" opinion (eg. from Proxmox) or how do other subscribers handle their subscription keys?
yes, it should be considered a secret (if only because if it leaks, you might temporarily lose your subscription status because someone else can re-issue it to a different server).


The Proxmox community has been around for many years and offers help and support for Proxmox VE, Proxmox Backup Server, and Proxmox Mail Gateway.
We think our community is one of the best thanks to people like you!
