Mobile users hate friction. Every extra field or forgotten password is another chance they’ll abandon your signup or checkout flow. Biometric login—Face ID, fingerprint, voice—shrinks that hurdle to a single gesture and unlocks real, measurable returns.

Users Already Prefer Biometrics

More than half of global smartphone owners authenticate with biometrics daily, and 72 % say they would rather use face or fingerprint than a password. In other words, you’re not teaching users something new—they’ve already made it a habit.

Four ROI Pillars You Can Take to the Board

1  Conversion Uplift

One-tap sign-in removes the “create password” drop-off. Apps adding biometric or passkey login see onboarding completion rates jump 10–25 %.

2  Lower Cart Abandonment

Returning shoppers skip credential entry at checkout. Even trimming abandonment by 5 % against the industry-average 70 % adds serious monthly revenue.

3  Help-Desk Cost Savings

No password means no resets. Each reset ticket can cost up to ₹ 5,000 / $70 in support time. Eliminate thousands of such tickets and the savings compound fast.

4  Fraud & Chargeback Reduction

Biometrics bind the session to the real user, driving double-digit drops in account-takeover fraud for early-adopter banks and fintech apps.

Krantecq in Action

When we integrated Face ID / fingerprint login into a React Native wallet app:

• Login success rose to 98 % (vs. 83 % with SMS OTP).
• Password-reset tickets fell to nearly zero, freeing an entire support head-count.
• Checkout speed dropped by 11 seconds, nudging conversions up 8 % in A/B tests.

Implementation Checklist (One-Sprint Starter)

• Scope device mix – iOS 15+, Android 11+; plan passkey fallback.
• Select library – react-native-biometrics or Expo LocalAuthentication.
• Token strategy – short-lived access + refresh tokens stored in Secure Enclave / Keystore.
• Fallback UX – PIN or OTP for unsupported hardware.
• Regulatory box-tick – consent screens; store no raw biometric data.
• Success metrics – track first-login completion, repeat login time, help-desk tickets, and funnel lift.

The Cost of Waiting

Password UX is already a liability. Competitors who ship biometric login first will capture the silent wins—higher conversion, leaner support, lower fraud—while your team still fights forgotten-password tickets.
