SMS OTP
SMS OTP (One-Time Password) is a one-time password sent to the user’s mobile phone via SMS to verify their identity and perform online transactions or access account information. This OTP has a limited time period or can only be used once to increase security and prevent unauthorized persons from accessing the information.
Usually, SMS OTP is a 4 or 6 digit code that has a limited time period. If the code is entered incorrectly or exceeds the specified time period, the transaction will not be successful.
SMS OTP and MFA (Multi-Factor Authentication)
SMS OTP is part of the Multi-Factor Authentication (MFA) process, which provides additional security for accessing accounts or data, preventing unauthorized access and effectively reducing transaction risks.
