1. What is 2FA (Two-factor authentication) and why it’s essential

When you sign in to your Nexo account, you must first enter your credentials, which consist of your email and password. This is known as the first level of verification or the first factor.

The second factor involves entering a unique, time-sensitive 2FA code for your account. This 2FA code is also required to make withdrawals and perform changes to your security settings.

2. What types of 2FA are available

You can find a list of all currently supported two-factor authentication options below:

  • Email
    Email 2FA allows you to receive the codes on your Nexo-registered email address. It is the default 2FA option set automatically during the account creation process.

  • SMS
    By choosing this method, you can have the 2FA code sent via SMS to your mobile device.

    Note: The option to receive 2FA codes via SMS can be accessed when your Portfolio Balance is at least 500 USD. However, if your current 2FA method is SMS, the functionality will remain active regardless of your Portfolio Balance.

You can change the authentication method according to your preferences in the Account management section of your account. Learn more here.

3. How to set up my 2FA

Upon creating your Nexo account and verifying your email address, the 2FA method is automatically set to email for ease of use and enhanced information security. However, we strongly recommend that clients manually change their 2FA method to an authenticator app as a more secure alternative. Since we cannot automatically do this, we suggest that clients follow the step-by-step instructions provided in this article.

5. What are the benefits of two-factor authentication

  • Fraud prevention mechanism.

    The majority of hacking attacks are successful due to weak or stolen passwords. 2FA makes it more difficult for attackers to access your account, as it requires additional verification besides your password.

    Therefore, you should use 2FA whenever possible, especially when it comes to your sensitive data.

  • Reduced Data/Funds theft.

    Adding the extra step to the log-in process means attackers will struggle to access your account and perform unauthorized transactions.

6. Common issues with 2FA

Authenticator app 2FA codes are based on time and thus require your phone to be in sync with the official time.

If your phone’s time is out of sync or changed time zones, the best way to fix it is to change the time settings on your phone from Manual to Automatic.

How to change the time zone settings of my phone

You can find step-by-step instructions for both iOS and Android devices in the table below:

On iOS On Android
1. Open the Settings app 1. Open the Settings app
2. Tap General 2. Tap General Management / Additional Settings
3. Tap Date & Time 3. Select Date and Time
4. Enable Set Automatically 4. Enable Automatic date and time

In the Android version of the Google Authenticator app, under Settings, there is a Time correction for codes option; tap it and then select Sync now.

If you see two positions for your Nexo account in your authenticator application, check which one works and delete the other one.

What to do if the problem is not resolved

If you still need assistance, contact Nexo through Nexo’s Live Chat channel, located in the lower right corner of this window, or through Nexo’s other support channels.

Depending on the problem, we might have to disable the 2FA on your Nexo account.

Please note that Nexo will require you to provide us with specific personal information for security reasons. Only then will we be able to disable 2FA authentication on your Nexo account.
