Email One-Time Passcode (OTP)
Secure Identity Verification Through Email
Email One-Time Passcode (OTP) provides a fast, reliable way to ensure the user actively controls the email inbox of a given email address before granting access to sensitive accounts, applications, or transactions.
Authentication API delivers a complete Email OTP solution through a simple API integration. We generate and deliver secure one-time passcode to the user's email address and validate the code when it is returned.
No email infrastructure. No security headaches. No complex implementation.
Just secure confirmation of email access through a single API.
Purpose: Ensuring the user actively controls the inbox.
HOW EMAIL OTP WORKS
1. Your application sends an API Request to us.
2. We generate a secure one-time passcode that is delivered to the user's email address.
3. The user enters the code into your application.
4. Your application submits the code back to us for verification.
5. We return an API response indicating a successful or failed match.
