OTP & Two-Factor Authentication
Secure logins and transactions with instant one-time passwords
One-Time Passwords (OTPs) and Two-Factor Authentication (2FA) via SMS are the most widely adopted method for securing digital access across every industry. Whether you are a bank, an e-commerce store, a healthcare portal, or a government service, SMS OTPs provide an instant, reliable security layer that works on every mobile phone — no smartphone or data connection required.
Account Login Verification: Require users to confirm their identity with a time-limited OTP sent to their registered phone number before completing a login. This single step dramatically reduces the risk of unauthorised account access, even when a password has been compromised.
Transaction Authentication: Protect high-value or sensitive actions — such as fund transfers, password changes, or profile updates — by demanding OTP confirmation before processing. Customers feel secure knowing that no critical action can be taken without their explicit approval via their mobile phone.
Registration & Onboarding: Verify new users' phone numbers during sign-up by sending an OTP to confirm ownership. This eliminates fake accounts, reduces fraud, and ensures your contact database contains only genuine, reachable customers from day one.
Universal Applicability: OTP via SMS is platform-agnostic and works for any digital service — from mobile banking apps and online marketplaces to government portals and subscription platforms. It requires no additional app installation from the user, making it the lowest-friction, highest-adoption 2FA method available.
