Frequently Asked Questions

One-time password (OTP) authentication is a system security measure in which a one-time-use code can be used only once for a single login attempt. An OTP will be sent to your registered email, and you need to enter the OTP to verify your identity in order to proceed with certain processes. This helps to minimize the risk of fraud attempts to login that misuse your account and maintain high security.
