Send One-Time Passcode (OTP) to your users and verify.

The OTP-Based Verification API is a service that provides a secure method for user authentication by generating and validating one-time passwords (OTPs). It ensures that only authorized users can access sensitive information or perform critical actions by requiring a valid OTP for verification.

The OTP-Based Verification API consists of two essential components:

Send OTP API: Generates and delivers OTPs to users via SMS. It supports OTPs of varying lengths (4, 5, 6, 7, or 8 digits) and allows for personalized message content.

Verify OTP API: Validates the OTP entered by the user against the one generated by the system to ensure the correctness and authenticity of the OTP for secure access.

The Send OTP API sends a one-time password to users via SMS. You can choose the length of the OTP based on your security needs and personalize the content of the OTP message to align with your branding and localization requirements. The API supports over 200 countries, including the US, Canada, UK, India, and UAE.

The Verify OTP API is used to check if the OTP entered by the user matches the OTP generated and sent by the Send OTP API. This verification process is crucial for securing user accounts and preventing unauthorized access or fraudulent activities.
