Because E-junkie itself is not involved in the payment process there is no way for us to store or access buyer payment information, and that is intentional as part of keeping that information safe.
If you haven't already you might look into enabling two-factor for your chosen payment processor as an added layer of security for the services processing your buyer payments.
As for adding two-factor as a general security measure for E-junkie Admin accounts, it is an option our Dev team is aware of & is currently on the 'wishlist' of things to have in the future.
