You're prompted to download a backup key when you set up two-factor authentication (2FA) in your account using the Authenticator App method. This code lets you restore access to your account in case of a changed or lost smartphone, or accidental deletion of the Authenticator App. That’s why keeping the key safe is very important – it helps you save time and recover access without contacting support.

How it works

If you have your backup key saved, follow these steps to recover the access:

1. Download the Google Authenticator app on your device and open it.

2. Find and press the "+" sign. It can be located in the bottom or top right corner depending on the device.

3. You will be prompted with options to either "Scan a QR code" or "Enter a setup key." Choose "Enter a setup key."

4. In the "Account name" field, type a name that will help you recognize the account (e.g., “CEX.IO”, “up****”).

In the "Your key" field, enter the backup key you were given when you initially set up two-factor authentication (2FA) for your account. This key usually consists of a series of letters and numbers.

In the "Type of Key" field: ensure the type is set to "Time-based" if prompted.

Once you've entered the backup key, tap "Add." The app will now generate a 6-digit code for your account.

5. Use the 6-digit code generated by Google Authenticator to log back into your account. This code will refresh every 30 seconds, so ensure you use the latest one displayed.
