UAE Banks Enter “Post‑OTP” Era As Biometric Security Becomes Standard

UAE banks are accelerating a systemic shift away from handwritten signatures and SMS one‑time passwords (OTPs) toward biometric login and AI‑powered fraud checks, marking the start of what industry executives describe as a “post‑OTP” era in Gulf banking.

A new Central Bank of the UAE directive, reported by Gulf News and regional media, is pushing banks to phase out SMS‑based OTPs in favour of in‑app approvals secured by biometrics such as fingerprint, facial recognition and device‑binding. The goal is to reduce SIM‑swap and OTP interception fraud while delivering a more seamless, paperless experience across mobile and online channels.

Leading lenders including Emirates NBD, First Abu Dhabi Bank and Abu Dhabi Commercial Bank have already rolled out biometric logins on their primary apps and are now extending in‑app authentication to card‑not‑present purchases, high‑value transfers and profile changes. Customers increasingly approve transactions via push notifications, with the app verifying identity using stored biometrics rather than codes sent over SMS.

AI is the second pillar of the new security stack. Banks are deploying machine‑learning models to score transaction risk in real time, flagging unusual device, location or behavioural patterns and escalating only suspicious transactions for additional verification. This reduces friction for legitimate users while tightening controls where it matters most.

The move builds on an already strong digital foundation. Khaleej Times recently reported that UAE banks are set for another year of strong performance in 2026, underpinned by robust profits, lending growth and rapid digital transformation. Industry estimates suggest more than 750,000 customers now use conversational‑banking tools like WhatsApp and in‑app chat, creating rich behavioural data that feeds AI‑driven security and personalization engines.​

Regulators see security and innovation as complementary. The Central Bank’s financial‑sector strategy for 2026 emphasizes digital transformation, payment‑system upgrades and stronger regulatory frameworks for both banking and insurance, including new rules on licensing and telemarketing to enhance consumer protection. Its earlier OTP guidance signalled a desire to move beyond legacy authentication toward modern, risk‑based approaches.

For customers, the transition requires adaptation. Banks are running awareness campaigns explaining why OTPs are being phased out, how biometric data is stored (typically on the device, not centrally), and what fallback options exist for customers with older phones or accessibility concerns. Early feedback suggests many users welcome fewer OTP interruptions, though some remain wary of relying solely on biometrics.

The UAE’s shift is being watched across the region. Bloomberg’s Gulf Regulatory Outlook 2026 highlights that GCC supervisors are increasingly focused on digital‑finance risk and operational resilience, with cyber‑security a core pillar. If the UAE’s biometric‑first model proves successful, Saudi Arabia, Qatar, Bahrain and Oman may follow with similar guidance.

For Asian peers, particularly in Singapore, Hong Kong and Australia, the UAE’s “post‑OTP” experiment offers another reference point in the global evolution of strong‑customer‑authentication regimes. As AI‑driven fraud and deepfakes grow more sophisticated, banks from Bangkok to Tokyo will need to continually reassess their own balance between user convenience and multi‑factor security.
