Registering for SMS One-Time-Password (OTP)
SMS OTP can provide more protection for your CDF Online account activities. We may send you a SMS OTP to verify a range of online activities, such as logging into your account and authorising payments. With the extra security of SMS OTP, you also have the ability to change your own password, at any time.
How does SMS OTP work?
A one-time passcode (OTP) is a single use passcode for only one CDF Online process or activity. We will send you a SMS OTP to your mobile phone number we have on our records, to confirm certain CDF Online actions.
Do not disclose this code to anyone, even if asked by someone purporting to be from CDF. Simply enter the code to complete your desired action.

How does it protect me?
SMS OTP is an example of multi-factor authentication which can provide an-additional layer of security.
1st factor – Something you know
Your username and password are the first-factor, or first layer, of authentication used to confirm your identity online.
2nd factor – Something you have
The second-factor is an additional authentication layer. A one-time password sent to your mobile phone provides this additional layer and may be requested to verify a range of online activities.
