This article applies to all versions of Connect Fonts
When you open Connect Fonts and log in, you get a warning:
The font vault in Connect Fonts is linked to the email address that creates it. If you try to log in to Connect Fonts and the current vault was created by a different email address, you get a warning and three options.
Clicking Cancel closes Connect Fonts; you can reopen the application and log in with the correct email address.
Clicking Select Vault brings up a dialog to choose a different font vault. After you select another font vault, Connect Fonts will restart; you can log in with the email address that created the newly-selected vault.
Clicking Create New Vault brings up a dialog so you can select a location for a new vault. Once you've selected the new location, Connect Fonts will restart; you can log in with the email address you want to use with the new vault.
