What is Two-Factor Authentication?

Two-factor authentication provides an extra layer of security. Since two-factor authentication apps are not tied to your phone number (you'll still need a phone number associated with your CoinZoom account in order to buy or sell digital currency), you will be protected even in the event of an attacker compromising your phone number.


When using Google Authenticator for your 2-step verification codes, you will still be protected even if your password is stolen and your phone number is ported. When using Google Authenticator, the only way to generate 2-step verification codes is by physically accessing your Google Authenticator app.

Google Authenticator 2FA Troubleshooting

Failure when attempting to send crypto to an external wallet

This can happen if there is a lock on funds that were deposited using a debit card.  Debit Card deposits are locked from being sent out of the exchange for 7 days from the time of deposit.



General Failure

Logging in using Google Authenticator can fail when the Google Authenticator app is not synced correctly.

To make sure that you have the correct time:

On Android
  • Go to the main menu on the Google Authenticator app
  • Tap Settings
  • Tap Time correction for codes
  • Tap 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.  Reference documentation
On iOS
  • Open the Settings app of your iPhone home screen
  • Tap General
  • Tap Date & Time
  • Disable Set Automatically Option and re-enable again
  • Reboot your device

If you'll keep experiencing issues with 2FA after completing these steps, contact support and we'll help you further.



What can I do if I lost the device with my 2 factor authentication?
We can help you get around the loss of your 2FA. We do need to ensure that we're working with the owner of the account.In order to do this we can schedule a ZOOM meeting. During the ZOOM meeting the account owner is required to be visible on camera showing the same documents they provided when they completed their KYC verification: Driver's License, Passport, etc.
Please create a support ticket by clicking on "+New Support Ticket" when you're ready to schedule the ZOOM meeting.

What two-step authentication apps can I use?

Currently, we only allow the Google Authenticator app.
