To help you comply with PSD2, we provide a client-side Authentication SDK that combines the possession factor with either the knowledge or the inherence factor. The SDK helps you configure a two-factor authentication feature that requires a secondary verification method through a separate communication channel, such as a mobile phone.
With Adyen's Authentication SDK, you can:
- Check if the user's device is eligible for Strong Customer Authentication (SCA).
- Register your user's mobile device to create device binding.
- Authenticate your user's subsequent actions.
The Authentication SDK integration also enables you to implement out-of-band authentication for Adyen-issued cards.
System requirements
We provide the client-side Authentication SDK in the following languages:
- Kotlin or Java for Android applications
- Swift for iOS applications
Before you start implementing the SDK, make sure that your system follows the requirements.
- Your application targets minimum Android API level 21 or later.
- The authentication feature works on devices running on Android API level 26 and later.
- The authentication feature requires Google Play Services on the cardholder's device.
To ensure the correct support type for 3D Secure on the card program, contact our Support Team.
