Improves the security in your business with SMS OTP authentication
SMS OTP, also known as SMS One-Time-Password, is a 6-digit code for two-factor authentication. It is an extra layer of protection used to ensure the security of financial transactions and online accounts. In the SMS OTP authentication method, OTP is sent via SMS text to the user’s phone. The user receives the OTP and enters it on the device where the authentication is happening. The OTP must be used within a specific time frame, reducing the risk of fraud in online transactions.
