# ThreeDSecureFlow

The flow used for 3DS authentication.

* `CHALLENGE` - Authentication requiring additional shopper interaction through biometrics, 2FA, or other SCA methods.
* `FRICTIONLESS` - Background authentication using device fingerprint without additional shopper interaction.
* `FRICTIONLESS_CHALLENGE` - Complete 3DS flow with additional authentication if initial data collection is insufficient.
* `DIRECT` - Transaction exempt from SCA due to low risk assessment.
