Open Banking & Identity: Navigating SCA & PSD2 Compliance

The rise of open banking, driven by regulations like PSD2 (Revised Payment Services Directive) in Europe and similar initiatives globally, is fundamentally changing the financial services landscape. While offering exciting opportunities for innovation and customer-centric services, open banking also introduces significant challenges related to security and, crucially, identity verification. Strong Customer Authentication (SCA) requirements are at the heart of these changes, demanding a shift in how financial institutions and third-party providers (TPPs) verify user identities.

Key Takeaway 1: PSD2 and SCA are increasing the complexity and cost of identity verification in open banking.

Key Takeaway 2: Traditional identity methods are often insufficient to meet SCA requirements and prevent fraud in the open banking ecosystem.

Key Takeaway 3: A layered approach to identity verification, incorporating behavioral biometrics and risk-based authentication, is essential for a frictionless and secure user experience.

Key Takeaway 4: Investing in a robust identity platform is no longer optional, but a critical component of compliance and competitive advantage.

Understanding the Open Banking Landscape & PSD2

Open banking enables third-party providers (TPPs) – fintechs, payment processors, and other financial innovators – to access customer banking data with their consent, facilitating services like account aggregation, payment initiation, and personalized financial management. This access is governed by regulations like PSD2, which aims to foster competition and innovation within the financial sector. A core tenet of PSD2 is SCA, which mandates multi-factor authentication for most online transactions, including those related to open banking.

Specifically, SCA requires the use of at least two independent elements from the following categories:

• Knowledge (something only the user knows, e.g., password, PIN)
• Possession (something only the user possesses, e.g., smartphone, hardware token)
• Inherence (something the user is, e.g., fingerprint, facial recognition)

The Challenges of SCA & Traditional Identity Verification

Implementing SCA isn't without its challenges. Traditional methods like SMS-based one-time passwords (OTPs) are increasingly vulnerable to SIM swapping fraud and phishing attacks. Moreover, relying solely on knowledge-based authentication (KBA) – security questions – is demonstrably insecure. These methods also create friction for legitimate users, leading to higher abandonment rates and a poor customer experience. The financial regulation surrounding open banking demands a more robust and secure approach to identity verification.

According to a recent study by Juniper Research, fraud losses related to open banking are expected to exceed $30 billion globally by 2027. This underscores the urgent need for more sophisticated identity solutions.

Leveraging Biometrics & Risk-Based Authentication

To overcome the limitations of traditional methods, financial institutions and TPPs are turning to advanced technologies like behavioral biometrics and risk-based authentication. Behavioral biometrics analyze user behavior patterns – how they type, swipe, and interact with their devices – to create a unique biometric profile. This provides a continuous layer of authentication without requiring explicit user action.

Risk-based authentication (RBA) assesses the risk associated with each transaction based on various factors, including location, device, transaction amount, and user behavior. Transactions deemed low-risk may require only minimal authentication, while high-risk transactions trigger more stringent checks. This adaptive approach minimizes friction for legitimate users while bolstering security.

The Role of Identity Orchestration Platforms

Managing the complexity of SCA and ensuring a seamless user experience requires a centralized and flexible identity orchestration platform. These platforms integrate various identity verification methods – document verification, biometric authentication, device fingerprinting, AML screening – into a single system, allowing businesses to create customized verification flows tailored to their specific needs. An effective platform streamlines the open banking user experience and reduces the operational burden of maintaining multiple vendor integrations.

Didit, for example, offers a single API to access a full suite of identity verification modules, including ID document verification, liveness detection, and AML screening. Our visual workflow builder allows businesses to design and deploy complex verification flows without writing a single line of code.
