What is SMS OTP?

SMS OTP (One-Time Password) is a temporary password generated automatically and sent to the user via SMS. This password is valid only once, ensuring secure access or transactions.

When to use an SMS authentication solution?

An SMS authentication solution is particularly useful in scenarios where additional security is required for user access, transactions, or identity verification. Here are key situations to consider using SMS authentication:

Securing User Accounts

Two-Factor Authentication (2FA):

To add an extra layer of security beyond passwords, SMS OTPs can verify user identity during login attempts.


Password Recovery:

Sending a temporary code via SMS helps users reset their passwords securely.

Preventing Fraudulent Transactions

E-Commerce Payments:

Verifying purchases with SMS OTP prevents unauthorized transactions.


Banking & Financial Services:

SMS authentication is a trusted method for confirming transfers, withdrawals, or sensitive changes in accounts.
