PSD2 SCA explained

The Revised Payment Services Directive 2

The Revised Payment Services Directive is a European regulation that creates a more open, competitive, and secure payments landscape across Europe. SCA requirements are part of PSD2.

Strong Customer Authentication

SCA is a requirement of PSD2. It's a combination of three elements to authenticate a payment, something you know, own, and are. For example: a password, your phone, your fingerprint.

3D Secure 2

3DS2 is the authentication solution that creates better shopper experiences while reducing fraud. Your customer gets a simple step in the payment process to allow the issuer (bank) to check that they are who they say they are. Or, in some cases skip authentication due to exemptions.
