Stripe. Credit Cards that require authentication in SAAS apps

Hi, I have SAAS app.
I’ve built Stripe straightforward, user can create Customer in Stripe, attach payment method and subscribe. For people with subscription status that contains “incomplete” I just show them error message.

I’ve just realized there should be cards that require authentication or something similar. Is it a problem for SAAS app?

I’ve just thought that “incomplete” status in Stripe is just for those cards that don’t have enought money.
