Install Token2 Burner App and make sure your token is accessible via NFC.
You can test NFC access by "get OTP" button of the app: push the button on the miniOTP-1 device and hold it close to the NFC antenna of your Android device (usually below the camera on the back). Then on the Burner App, touch "get OTP" button. The OTP shown on the app should match the one displayed on the token.
Find the 2-Step Verification settings for your account
Log in to your Gmail account, go to My Account.
Choose “Sign-in & Security” tab.
Click “Signing in to Google”.
Select “2-Step Verification”.
Enter your phone number and select a method to get codes > click “Next”.
You receive an SMS on your phone with a code. This is a requirement of Google, the phone number will be used to restore access in case access to the authenticator app (or in our case the miniOTP token) is lost or the profile is corrupted.
Enter the verification code to confirm that it worked – click “Next”.
Now, turn on 2-Step verification.
For the best user experience, Google recommends to set up the Authenticator App. We will have to select this option as our burner app is using the same QR code shown for Google Authenticator to set the seed of the miniOTP token.
Select iPhone as your kind of phone and click “Next” (selecting Android phone may change the process of enrolling, especially if you are using the same Google account on your Android devices)
On the next step, the QR code should appear on the screen.
Now, launch Token2 Burner App on your Android device. Click on Scan QR button and scan the QR code shown on the configuration page as described in the previous step. Then, push the button on the miniOTP-1 device and hold it close to the NFC antenna of your Android device (usually below the camera on the back). Click on "burn seed" button. The app should show "burn seed process succeeded" message if the process is successfully completed.
After the process is completed, your miniOTP token is now generating OTP codes for your Gmail account.
Click “Next” under QR code.
Enter the 6 digit code generated on your miniOTP token device to the Google Verification Code field and click “Verify”.
Q. Can the miniOTP-1 token be reused for another user (i.e. if the previous owner no longer needs it)?
A. Yes. the miniOTP-1 tokens are reprogrammable for an unlimited number of times. So the steps described above can be repeated for any user using any miniOTP-1 device (even previously owned).
