The security of your funds is of utmost importance to us, which is why we have implemented various measures to ensure all assets are safe and secured. One way we do this is through two-factor authentication (2FA) to prevent any potential hacks and scams. 

To ensure a high level of security, users would have to undergo several steps associated with setting up 2FA to verify their identity. If you’re unsure of these steps, we're here to help.

In this guide, we will cover the following:

  • What is 2FA
  • Why is 2FA Important
  • A Step-by-Step Guide to Setting up 2FA on the iOS Mobile App
  • A Step-by-Step Guide to Setting up 2FA on the Website

What is 2FA?

Two-factor authentication (2FA) is known to be one of the most commonly used methods of security to reduce any potential risks of users falling victim to an account takeover. 2FA is ideal as it complements many traditional forms of authentication like passwords to ensure accounts are protected.

As its name suggests, 2FA requires two different types of authentication for a user to be allowed access to their account.

Why is 2FA Important?

The fact is, having passwords alone is not enough of a security measure to protect your account. Reports have shown that 65% of individuals use the same passwords for multiple accounts. This would mean that if a hacker gets access to your password, he will gain access to all the accounts with the same password.

Having 2FA in place would add an additional layer of security. This would mean that even though a hacker does gain access to your password, it would not lead to an account takeover since the chances of having access to both factors are improbable. 

This is why Hodlnaut has put in place 2FA to ensure that users’ accounts are well secured and protected, preventing any potential hacks and account takeover. 

A Step-by-Step Guide to Setting up 2FA

If you’re unsure of how to set up 2FA on your Hodlnaut account, here’s a simple step-by-step guide to help you through the process.

Troubleshooting When 2FA is Invalid 

2FA may be invalid

At times, your 2FA may be invalid as seen in the images above. This issue may occur due to the inaccurate generation of the 2FA code. To solve this, there are several options to consider.

Manual time settings and offline devices tend to slip out of sync, which will hinder the successful generation of correct 2FA codes. If your phone's time is out of sync, or if you have changed time zones, the best way to fix it is to change the time settings on your phone from "Manual" to "Automatic".

To Change Time Settings from 'Manual' to 'Automatic' (iOS):

  • Go to your phone’s Settings app
  • Select General
  • Select Date & Time
  • Enable Set Automatically

To Change Time Settings from 'Manual' to 'Automatic' (Android):

  • Go to your phone’s Settings app
  • Select General Management
  • Select Date & Time
  • Enable Automatic date and time

If your system time is already set to automatic, please disable and re-enable it.
However, if you are on Android and the first solution did not work for you, this might be because the time on your Google Authenticator app is not synced correctly.

When Your Google Authenticator Codes are not Working (Android):

To make sure that you have the correct time:

  • Go to the main menu on the Google Authenticator app
  • Tap on More and click on Settings
  • Tap on Time correction for codes
  • Tap on Sync now

On the next screen, the app will confirm that the time has been synced, and you should now be able to use your verification codes to sign in. The sync will only affect the internal time of your Google Authenticator app and will not change your device’s Date & Time settings.

Resetting of 2FA
