Do I need a USB token?

Yes, as per guidelines, Class 3 DSCs must be stored on a secure FIPS-compliant USB token rather than downloaded to a computer.

Is a separate DSC needed for each portal?

No, one valid Class 3 DSC can be registered and used across MCA, GST, income-tax, EPFO and tender portals.
