AEM Crypto Support | HMAC and Master Keys sync

Hello Team , I have one question on hmac and master keys sync on author and publish servers- https://experienceleaguecommunities.adobe.com/t5/adobe-experience-manager-blogs/crypto-support-in-aem-syncing-keys-among-aem-instances-aem/ba-p/377747 I assume this activity of syncing these keys is just a one-time thing- once done for the author and publish servers we could use the same encrypted password in the author and publish servers? Can someone confirm this understanding? Thanks, Pallavi Shukla
