Background of the Study
As cyber threats evolve, the security of digital transactions becomes a critical concern for banks. Citibank Nigeria has recently upgraded its online authentication systems to fortify the security of its digital banking channels. The upgrades include multi-factor authentication (MFA), biometric verification, and advanced encryption techniques that protect sensitive customer data during transactions (Ugochukwu, 2023). These measures are designed to prevent unauthorized access and mitigate risks associated with identity theft and fraud. By implementing real-time threat monitoring and automated security audits, Citibank Nigeria aims to provide a secure digital environment that builds customer trust and fosters increased adoption of online services. Enhanced authentication protocols are integrated with the bank’s broader risk management framework, ensuring that any suspicious activities are promptly detected and addressed. Research shows that robust online authentication mechanisms are crucial for reducing cyber fraud and enhancing customer confidence in digital banking (Okeke, 2024). However, there remains a delicate balance between stringent security measures and maintaining a user-friendly interface. This study explores how these authentication system upgrades impact the security and usability of digital transactions, thereby influencing customer trust and digital engagement.
Statement of the Problem
Despite the implementation of upgraded online authentication systems, Citibank Nigeria continues to face challenges related to user experience and system reliability. Some customers report difficulties with the multi-factor authentication process, which can lead to delays and frustration during login attempts (Chukwu, 2024). Integration issues between the new security protocols and existing legacy systems have occasionally resulted in technical glitches, compromising the overall smoothness of digital transactions. Furthermore, while heightened security is intended to build trust, overly complex authentication steps may deter less tech-savvy customers from using digital services. This gap between the intended security enhancements and the practical user experience undermines the bank’s efforts to secure digital transactions and expand its online banking base. Therefore, it is necessary to evaluate the effectiveness of the upgraded authentication systems and identify measures to optimize both security and usability, ensuring that customer trust is maintained without compromising convenience (Ibrahim, 2023).
Objectives of the Study
