  3. User Experience vs. Security: While HSBC wanted to ensure maximum security, it also needed to maintain a user-friendly experience for customers, many of whom found traditional authentication methods cumbersome.
  4. Regulatory Compliance: Banks must comply with stringent regulatory requirements, such as PSD2 (Payment Services Directive 2) in Europe, which mandates strong customer authentication to reduce fraud.

Recognizing the growing need for a secure yet convenient solution, HSBC turned to biometric authentication to address these challenges.

What is Biometric Authentication?

Biometric authentication uses unique biological characteristics—such as fingerprints, facial features, voice patterns, or iris scans—to verify an individual’s identity. Unlike passwords or PINs, biometrics are much harder to replicate, providing a higher level of security. Common biometric authentication methods include:

  • Fingerprint recognition: Scans a user’s fingerprint to confirm their identity.
  • Facial recognition: Uses the phone’s camera to analyze and confirm the user’s facial features.
  • Voice recognition: Analyzes the user’s voice patterns for authentication.
  • Iris or retinal scanning: Uses the eye’s unique features for verification.

HSBC decided to implement fingerprint and facial recognition, two of the most widely used and secure forms of biometric authentication, for its mobile banking app.

Key Challenges Faced by HSBC Before Implementing Biometric Authentication

Before adopting biometric authentication, HSBC encountered several security and operational challenges:

  1. High Risk of Account Takeovers: Mobile banking accounts were increasingly targeted by cybercriminals using stolen credentials. Weak passwords and traditional authentication methods were insufficient to protect against these attacks.
  2. Customer Frustration with Traditional Authentication: Customers found the process of entering passwords and PINs time-consuming, especially on mobile devices, leading to a poor user experience.
  3. Complex Fraud Detection: Identifying and preventing fraud in real-time was becoming more complex due to the variety of attack vectors targeting mobile applications.
  4. Compliance with Regulatory Mandates: HSBC needed to comply with PSD2 and other regulations that required strong customer authentication (SCA) for online payments and account access.

HSBC’s Approach to Implementing Biometric Authentication

To address these challenges, HSBC implemented secure biometric authentication for its mobile banking app. The solution was designed to enhance both security and convenience for customers.
