As the UAE accelerates digital transformation across government, finance, healthcare, and smart infrastructure, strong authentication is no longer optional—it’s mandated by authorities like NESA, ADSIC, and the UAE PDPL. Unfortunately, SMS-based two-factor authentication (SMS 2FA) is inherently vulnerable to attacks that put your data, your customers, and your regulatory compliance at risk. In this post, we’ll cover:
Key vulnerabilities of SMS 2FA

Best practices for implementation and compliance
How eMudhra’s solutions accelerate your migration to secure authentication
SIM Swap & Port-Out Attacks
Fraudsters socially engineer telecoms agents or exploit SS7 network flaws to hijack phone numbers.
Once the phone number is ported, attackers intercept all incoming SMS OTPs.
Lack of Encryption
SMS travels over legacy telecom channels in plaintext. Rogue insiders or compromised infrastructure can read OTPs in transit.
Phishing & Man-in-the-Middle (MitM)
Attackers mimic legitimate login pages and phish both passwords and SMS OTPs in real time, bypassing 2FA entirely.
Mobile Malware & Message Forwarding
Sophisticated spyware on smartphones can exfiltrate SMS messages, including OTPs, without user knowledge.
Regulatory Pressure
UAE cybersecurity frameworks (NESA’s Cybersecurity Standard, ADSIC Digital Trust guidelines) specifically discourage reliance on SMS OTPs for high-assurance use cases.
How it Works: Authenticator apps (Google Authenticator, Microsoft Authenticator) generate 6-8 digit codes every 30 seconds—no network required.
Pros:Resistant to SIM swap and SMS interception
Offline operation
Easy to deploy across cloud and on-prem apps
Device loss requires recovery workflows
How it Works: Users receive a push notification on a registered device. They approve or deny the login with one tap.
Pros:Phishing-resistant—approval is tied to your device
Contextual metadata: IP, geolocation, device posture
Supports biometric confirmation (face/fingerprint)
Requires internet connectivity
How it Works: Leverage built-in smartphone or laptop sensors (fingerprint, Face ID, iris) as a second factor.
Pros:User-friendly and fast
Bound to the individual, not easily shared or stolen
Must comply with PDPL biometric data storage rules
How it Works: Cryptographic credentials—on a security key (YubiKey) or platform authenticator—replace passwords and SMS.
Pros:Phishing-proof: credentials never leave the device
Supports true Zero Trust: device-bound, user-verified
Seamless integration with modern browsers and mobile OS
Initial onboarding of keys/devices
How it Works: User and device certificates issued by your public key infrastructure (PKI) are used for mutual TLS or smart-card logins.
Pros:Highest assurance level for government, finance, and critical infrastructure
No reliance on passwords or SMS
Fully auditable and compliant with NESA, ADSIC, and ISO 27001
Requires PKI deployment and certificate lifecycle management
Risk-Based MFA Policies
Apply stronger factors (FIDO2, PKI) for high-risk workflows (transaction approvals, admin access).
User Experience
Offer a choice (TOTP, push, biometrics) to maximize adoption and reduce support tickets.
Integration & Automation
Use an identity and access management (IAM) platform that unifies MFA across on-prem, cloud, and mobile.
Regulatory Alignment
Map your MFA controls to NESA standards, ADSIC guidelines, and UAE PDPL requirements in your compliance documentation.
Continuous Monitoring
Feed MFA logs into your SIEM to detect unusual access attempts or device anomalies in real time.eMudhra helps UAE organizations deprecate SMS 2FA and adopt modern, regulation-ready authentication:
SecurePass IAM: Integrates TOTP, push-based, biometric, FIDO2, and PKI factors under one roof.
PKI Solutions (emCA): Deploy a robust enterprise or national PKI for certificate-based authentication.
Compliance-First Design: Pre-configured policies to meet NESA, ADSIC, PDPL, ISO 27001, and GDPR mandates.
User Self-Service: Streamlined device registration, recovery workflows, and admin delegation for large user bases (1,000+).
SMS 2FA is no longer sufficient for securing sensitive UAE environments. By embracing modern MFA—from TOTP to PKI-based authentication—you boost security, cut fraud, and stay ahead of regulators.
