Biometrics are no longer just a faster way to unlock a banking app. They are becoming part of the trust layer that banks will use to verify customers, approve payments, reduce fraud and remove friction from digital financial services. As passwords, OTPs and call-centre checks become weaker against scams and social engineering, banks are moving toward authentication models that prove not only what a customer knows, but who they are and whether the transaction context is safe.
Why biometrics matter now
The shift is being driven by three forces: rising payment fraud, customer frustration with OTPs, and the growth of mobile-first banking. The ECB and EBA reported that payment fraud in the European Economic Area rose to €4.2 billion in 2024, while noting that strong customer authentication remains effective but fraudsters are adapting.
At the same time, regulators are opening the door to newer authentication methods. India’s RBI, for example, has issued digital payment authentication directions effective from April 1, 2026, allowing risk-based checks and emerging authentication technologies beyond traditional OTPs.
From passwords to passkeys
One of the biggest changes will be the rise of passkeys, which allow customers to sign in using the same method they use to unlock their device, such as fingerprint, face scan, PIN or pattern. FIDO describes passkeys as cryptographic credentials tied to a user account, reducing dependence on passwords and additional factors.
For banks, this matters because authentication becomes harder to phish. A fraudster may trick a customer into sharing an OTP, but it is much harder to steal a biometric-backed passkey that is bound to a device and verified cryptographically.
Biometrics will reshape payments
The impact will go beyond app login. Mastercard has said it aims to phase out manual card entry for e-commerce by 2030, using tokenisation, Click to Pay and biometric passkeys to create a one-click checkout experience.
This points to a future where customers approve payments through face or fingerprint verification instead of entering card details, passwords or OTPs. For banks, that could reduce failed transactions, lower fraud risk and improve customer conversion at checkout.
The risk: biometrics cannot be reset
The biggest challenge is that biometric data is permanent. A password can be changed. A card can be replaced. A face or fingerprint cannot. That makes data protection, encryption, consent and storage architecture critical.
Banks will need to avoid treating biometrics as just another convenience feature. They will need clear policies on liveness detection, spoofing prevention, biometric template storage, fraud liability and customer opt-outs. The winners will be institutions that combine biometrics with risk-based authentication, behavioural analytics and strong device binding rather than relying on a single factor.
What this means for the industry
- Banks will compete on trust, not just app design. Authentication will become a visible part of customer experience.
- OTPs will gradually lose importance. They will not disappear immediately, but they will become less central as passkeys and biometric approvals scale.
- Fraud prevention will become more contextual. Banks will assess the user, device, behaviour, location and transaction risk together.
- Biometric governance will become a board-level issue. Data protection failures involving biometric identity could carry higher reputational damage than ordinary credential breaches.
- Financial inclusion will need safeguards. Customers without advanced smartphones, stable connectivity or comfort with biometric systems must not be excluded.
