Business Challenge

The financial institution faced significant challenges, including:

  • Large-scale Digital Footprint: Serving millions of users across retail, corporate, and merchant channels increased complexity
  • Fragmented Authentication Systems: Different, channel-specific authentication tools lacked a unified approach
  • Limited Authentication Options: Heavy reliance on SMS-based OTPs exposed security and fraud risks
  • Rising Cyber Threats: Existing authentication mechanisms were insufficient against evolving attacks
  • Regulatory Pressure: Stricter guidelines required stronger, out-of-band, and multi-factor authentication methods.

Our Approach and Solution

Tech Mahindra implemented a platform‑centric authentication strategy to help a large banking institution overcome fragmented authentication systems, rising security threats, and evolving regulatory demands. The objective was to create a single, unified authenticator that could securely support multiple banking channels while delivering a consistent and user‑friendly experience at scale.

The approach included:

Unified Authenticator

A single application enabling secure access across retail, corporate, and merchant banking channels.

Multiple Authentication Methods

Support for secure OTPs, push approvals, QR‑based verification, and biometric authentication.

Personalization and Control

Preferred authentication modes (selected by users), administrative controls for consistent policy enforcement.

Security by Design

Device and SIM binding, industry‑grade encryption, and secure login mechanisms.

Cloud‑native Architecture

An API‑first, highly available platform enabling scalability and rapid onboarding of new channels.

Operational Excellence

DevOps-driven delivery with continuous deployment, proactive monitoring, reduced operational overhead, and improved customer trust.
