Account takeover (ATO) fraud continues to be one of the most significant challenges facing retailers and e-commerce businesses attending the Fraud Prevention Summit…
As consumers increasingly store payment details, loyalty rewards, delivery information and personal data within online accounts, these profiles have become highly attractive targets for cybercriminals. Once compromised, accounts can be used for fraudulent purchases, loyalty point theft, identity abuse and wider financial crime.
The growth of credential stuffing attacks, phishing campaigns and stolen password databases has made account takeover a persistent risk for merchants of all sizes. For fraud prevention leaders, strengthening customer authentication is therefore becoming a critical component of wider fraud management strategies.
Passwords Alone Are No Longer Sufficient
It goes without saying that username and password combinations are increasingly ineffective against modern fraud tactics.
Many consumers continue to reuse passwords across multiple online services, meaning credentials exposed through unrelated breaches can often be used to gain access to retail accounts. Automated attack tools allow fraudsters to test large volumes of stolen credentials quickly, increasing the scale and speed of attacks.
As a result, retailers are moving towards stronger authentication frameworks that combine multiple layers of identity verification.
Multi-factor authentication (MFA) remains one of the most effective tools available, requiring customers to verify their identity through additional factors such as:
- one-time passcodes;
- biometric authentication;
- device verification;
- authentication apps; and
- security keys.
However, successful implementation requires balancing security with customer convenience.
Reducing Friction While Strengthening Protection
One of the biggest challenges surrounding MFA is customer adoption. Additional authentication steps can create friction within login and checkout journeys, potentially leading to abandoned purchases or increased customer support enquiries. This is particularly important in competitive retail environments where convenience often influences customer loyalty.
To address this, many organisations are adopting risk-based authentication models. Rather than challenging every user equally, modern authentication platforms assess factors such as:
- device reputation;
- geolocation;
- login behaviour;
- transaction patterns; and
- account activity history.
Low-risk users can proceed with minimal disruption, while higher-risk activities trigger additional verification requirements.
This approach helps strengthen security while preserving a positive customer experience.
MFA Is Becoming Part of a Layered Fraud Prevention Strategy
Increasingly, retailers recognise that MFA should not operate in isolation. Effective account protection strategies often combine authentication with:
- behavioural analytics;
- device intelligence;
- fraud monitoring platforms;
- bot detection tools;
- transaction risk analysis; and
- customer education initiatives.
Behavioural analytics can be particularly valuable in identifying suspicious activity that may not trigger traditional security controls. Unusual typing patterns, navigation behaviour or account activity can provide early indicators of compromise.
At the same time, educating customers about phishing attacks and credential security remains an important component of fraud prevention.
Building a Stronger Authentication Framework
When developing an account protection strategy, fraud prevention leaders should consider:
- Implementing MFA across customer accounts
- Adopting risk-based authentication controls
- Monitoring for credential stuffing activity
- Using behavioural analytics and device intelligence
- Protecting loyalty and rewards accounts
- Integrating authentication with fraud monitoring platforms
- Establishing clear incident response workflows
- Educating customers about phishing and password security
- Regularly reviewing authentication effectiveness
- Balancing security controls with customer experience objectives
Authentication Is Becoming a Competitive Advantage
Customer authentication will play an increasingly important role in both fraud prevention and customer trust. As account takeover attacks continue to evolve, retailers will need more intelligent and adaptive approaches to identity verification. The most effective strategies will be those that combine strong security controls with seamless customer experiences.
Many fraud prevention leaders are now building authentication frameworks that protect customers, support commercial performance and strengthen confidence in digital commerce over the long term.
