Everything you need to know about Strong Customer Authentication (SCA)

What is Strong Customer Authentication?

Strong Customer Authentication makes payments more secure for both your business and the customer by adding an extra layer of protection known as two-factor authentication (2FA). When SCA comes into effect, customers will be required to provide at least two of the following forms of identification when making a payment which includes, something the customer knows such as a pin or password, something the customer possesses such as a smartphone or something the person is such as biometric fingerprints
