[Guide] Two-Factor Authentication (2FA) Configuration

Hello CEX.IO users,

 

Two-factor Authentication is a proven way to add an extra layer of security, and is very useful for online services such as email and other crucial tools.

Security for access to online financial services is a must for participants, both small and large scale.  We work to make sure that all accounts are protected from any possible attacks, and offer 2FA level security as default.

CEX.IO offers two services for users to control 2FA access on their account.

 

SMS/Phone call

    1. SMS + Voice call

This type of 2FA service provides codes via SMS or voice calls to users which further can be used to access the account. In order to activate this service you are required to have a valid and working phone number.

In case you want to change phone number associated with this service you are kindly requested to contact support team by opening a ticket explaining the issue or write to support@cex.io.

 

Google 2FA

    1. Google 2FA applications are available for Android/iOS/WindowsPhone.  
    2. To scan the QR code, you will need a barcode scanner app installed.
    3. The activation screen shows the QR code and digit code which can both be input.

You can make your own back up by printing the displayed activation and QR codes on paper and keeping them safe.  The paper code can be used to install the access codes for your account to a fresh app install, if your device is lost or reset.

There are two ways to be verified, so we can process your Google 2FA disable request:

a) Depositing address signature:

Users can sign their depositing address if they used a Bitcoin wallet client or advanced online wallet with access to the private keys.  We can verify you as the true account holder if you are able to sign your depositing address.

 b) Account Security information Verification

To manually disable Two Factor settings, we have to be sure that you are true account holder and we will request account verification information from you.  Verification information will be sent to our security department for investigation.  We will contact you if we need additional information.

NB: If you do not save the activation codes for your Google app install, you will need us to verify you for manual disable by one of the above methods.

 _________________________________

NB (Risk warning): Two-Factor Authentication can also be disabled completely from user accounts by using the verification code and ticking that you are aware of the security risk warnings.

This completes the Guide for how to re-configure Two Factor Authentication, our aim is make sure your account is secure, and let you have optimum control.  If you are experiencing issues with security features, then please write your comment below, and open a ticket request if urgent.
