My Local Vault is not showing a secure connection icon in the URL bar. Is my connection secure?
Not to worry, this is not a "connection" at all. It is a completely local page, meaning there is no network activitiy at all. Because there is no web requests being made, there is no padlock icon to show -- that is only for actual web requests.
