What is OTP service?

A one-time password (OTP) is an automatically generated numeric or alphanumeric string of characters used by businesses to ensure a secure user flow.

OTP service is the easiest way of verifying user information and authenticating online transactions. Used by businesses to boost data security and prevent phishing attacks, an OTP service provider ensures timely delivery of OTPs to the right customers via SMSes and voice calls.

How can businesses use OTP service

Two-factor authentication (2FA)

Implement an extra layer of security in your systems, without adding complexity to your customers.

Spam prevention

Effectively control spam registrations, and avoid fake signups. Optimize and secure your backend systems against spam.

Password Resets

Instead of sending codes or links via email, use the OTP service to verify users before password resets.

Passwordless logins

Do away with passwords as your customers can be verified using an OTP every time they log in to your system.

Account Reactivations

Reactivate a user account with a confirmed acceptance from them. Use OTP verification as a means of verifying identity.

Transaction Authentication

Keep all transactions safe and sound. Add an additional layer of security with OTP verification to ensure safe transactions.

Passwords have been the primary form of customer authentication since the beginning of the internet. However, having a password-only authentication system will put businesses at an increased risk of data breaches, phishing attacks, and security threats.

Therefore, most businesses use OTP services to implement two-factor authentication (2FA) into their login systems or transaction portals.

With two-factor authentication enabled, your customers will need a one-time password or OTP (in addition to their registered password) to complete the transaction.

Any business that deals with sensitive customer information can make use of our OTP services. Some examples of the sectors that use OTP services are banking, healthcare, e-commerce, insurance, transport, etc.
