Stripe.js - Stripe 3D Secure shows and disappears after few seconds

Question

I'm integrating Stripe into my project and all is working fine. Except for one weird error with the 3D-secure modal.

When I use the test card that requires 3DS, the modal pops up and works fine. But when I use the normal card 4242 4242 4242 4242 using if :amount_in_usd: > 100.00 Authentication rules [Authentication rules Image][1]

The modal shows for a few seconds and then disappears then goes to the redirect_url without authenticating & do the payment with success.

My Payment Intent status is "requires_payment_method"

Answer 1

The Stripe 4242 test card is not enrolled for 3DS. Therefore when calling confirmPayment, then authentication flow is skipped as the payment is exempt from SCA regulations.
