Artjom-Navy-Panther Hi 👋🏼 Artjom,
That is an idea 💡. I think others bunqers 🌈 did mention this also before.
A merchant only needs the CVC code for the first payment so they can check if you really own the card 💳. All payments after that don't need the CVC anymore.
So, to have separate cvc codes for your online cards doesn't make it that more safer.
