OTP as a Service (One-Time Password service) is a cloud-based authentication solution that enables businesses to send secure, time-sensitive passwords to users for identity verification. These OTPs are typically delivered via SMS, email, voice calls, or mobile apps, ensuring an extra layer of security during login, transactions, or account recovery.
OTP as a Service eliminates the need for companies to build their own authentication infrastructure. Instead, they can integrate APIs provided by service vendors to quickly implement secure verification systems. This approach improves user trust, reduces fraud risks, and ensures compliance with modern security standards.
It is widely used in industries like banking, e-commerce, healthcare, and fintech, where secure access is critical. Features often include real-time delivery, global coverage, high scalability, and detailed analytics.
