Must a Norton product, like Norton Security, be installed on a particular computer if a user is to be able to use Identity-Safe a sign-in to his log-in combination for a website? This would assume that the browser is Google Chrome and Identity-Safe Toolbar is added as an extension from the Chrome Web Store, but that no other Norton product is installed (NONE of Nortons neither of Norton Security, Norton 360, Norton Internet Security, Norton Anti-Virus,... no anything of Norton), and that the user previously created and added log-in combinations to a Cloud Vault.
