Hi @Greg Booth ,
You do not need to refreshe the Secure Store encryption key on the SP 2013 instance before we backup up the SP 2013 secure store database.
Updating a server key is required when:
--A new SharePoint server that will run a Secure Store service instance is joined to the farm. --The key stored in the server is not the key required for the current Secure Store service database (because of server or networking issues). --The master key is updated but during propagation of the new key, this process fails on one or more of the servers.
You just updated the password you use to log into the sharepoint farm. You do not need to refreshe the Secure Store encryption key.
