LoginRadius Strong Customer Authentication (SCA) Product Sheet
Replace weak SMS OTPs with a structured authentication framework that combines multi-factor authentication with cryptographic dynamic linking, ensuring every authentication event is explicitly tied to a specific transaction context.Key Benefits of Strong Customer Authentication (SCA)
Stronger Fraud Resistance
Significantly reduce exposure to account takeover (ATO) and transaction manipulation by replacing SMS-based authentication with device-bound Push MFA and Passkeys.
Chargeback Liability Alignment
Proper SCA enforcement supports regulatory liability shifts for fraudulent transactions, drastically reducing financial exposure for merchants and platforms.
Reduced User Friction
Utilize modern authentication methods, such as biometrics, to streamline the user verification process without sacrificing strong security controls.
Regulatory Readiness
Aligning your platform with PSD2 SCA requirements ensures you meet the evolving global standards for open banking and data protection.
Why LoginRadius
Cryptographic Dynamic Linking
Pair a user’s MFA approval directly to the specific payment amount and payee on the backend using unique, server-generated linking_ids. If any transaction details are altered mid-checkout, the authentication state is automatically invalidated.
Isolated Back-Channel Authorization
Keep sensitive payment metadata out of front-channel browser URLs. By using Pushed Authorization Requests (PAR), transaction parameters are securely transmitted exclusively through backend channels.
Rich Transaction Context
Use Rich Authorization Requests (RAR) to inject structured transaction payloads—such as the amount, currency, and payee identifiers—straight into the authorization flow.
Risk-Engineered Identity Orchestration
Visually map user journeys and run custom serverless evaluation scripts to dynamically assess risk contexts against external engines before prompting additional verification.
