Toggle fully supports Strong Customer Authentication (SCA) 3D Secure 2; any guests who want to make a payment with 3DS V2 enabled cards will be able to do so.

On the 14th March 2022, Strong Customer Authentication (SCA) became a requirement for e-commerce sales in the UK. SCA helps confirm the identity of your guests via a set of rules, before a payment is authorised - with unauthenticated transactions declined.
