No, I’m saying the BG embedded SCA mode contradicts best security practice.
I’m not an expert in payments, but here is my take:
Apple Pay works differently as the credit card is tokenized and I assume Apple never sees the user’s credentials with the bank.
EMV at the POS is closer to the embedded mode as everything, including the PIN, goes through the terminal. Security is ensured by tight control over the participants - the whole approach is everything but open.
In online use cases, 3DS uses the break out to let the issuer ask the user for her credentials, which is more OAuth alike.
The world is a bit more complicated than black and white.
