Does the SSH Public Key Associated With My Connection Ever Change?

Question

I've connected my database to Fivetran using an SSH tunnel. When I edit my connection details in Fivetran, I can see and copy a Public Key. Does this SSH public key ever change?

Environment

• Database connectors
• Connection method: SSH tunnel

Answer

No, the SSH public key remains the same. Fivetran generates a unique SSH public key for each destination, not for individual connections. All connections writing to the same destination use that key to secure their SSH tunnel.
