Then, click on "Configure" button under Two-Factor Authentication section
On the next window, choose "a 2FA app" in the "Choose which app you want to use" drop-down list.
This will show the QR code that you need to scan using your Token2 NFC Burner app in the next step.
Install Token2 NFC Burner app on your Android device if you have not already done so. Make sure the correct app is installed - there is a separate app for each category of the devices. You can use this page to find which app is needed for your device (choose your model and the platform, you will get the app guides or links on the right column). The Android app we will be using for this example, for miniOTP-2 model, is this one.
Open the Token2 Burner app on your mobile device and click the button to scan a QR code, or manually enter the authentication key (base32 format is to be used). To scan the code, point your devices camera at the QR code seen in the setting of your Mailo account (see the previous screenshot).
Once the seed field has been filled, touch the "Burn seed" button, then turn the hardware token on and touch the top of the device. The process completion (or any errors) will be shown in the 'Results' area. Turn the token off and on again.
To complete the process, turn the hardware token on and enter the 6 digit code generated into the "Authentication code" field on the Mailo interface.
Mailo also asks to enter your current password for security purposes. If both the OTP and the password are entered correctly, clicking on Enable will complete the process.
