iOS NFC Burners for single profile Token2 programmable tokens



This page describes apps that can be used to program and configure our single profile hardware tokens using Apple iPhone devices. Kindly note that only iOS compatible tokens can be used with these apps. iOS compatible token models will have "-i" appended to their part number. As of now (June 2020) only two model (C301-i and C302-i) is available and we will introduce other iOS compatible models later this year.

Compatibility

All iPhones starting from iPhone 7 support NFC (iPhone 6 and 6S have the required hardware but Apple somehow limited access to these chips, so it’s not usable to third parties). None of the iPad models has the chip, nor do iPod touch devices. While our burner apps will most probably work on all devices mentioned above, we were only able to test on the following models so far: iPhone 8, iPhone X, iPhone 11.

Burner apps

We have released two different apps with a different set of features: TOKEN2 NFC Burner and TOKEN2 TOTP+. The apps are reviewed below.

TOKEN2 NFC Burner

This is a simple NFC burner and is very similar to our Android app. In addition to burning the seeds, the app will also allow configuring advanced settings, such as the hash algorithm (sha-1 or sha-2), the time offset (30 seconds or 60 seconds), the display power-off time out (from 15 seconds to 120 seconds) and time synchronization.

Burning a seed

The main window of the app is allowing to burn a seed to a programmable token by scanning the seed QR code or typing it in manually. This is the only screen you will be using in 99% of the cases.

  • To burn a seed, launch the app, then touch the 'Scan QR' button to scan a TOTP QR code using your camera. If the provisioning needs to be done by typing in or pasting a seed in text format, you can enter the seed in the 'Seed (in hex)' field if the secret is in hex format, or touch 'enter in base32' button if the seed needs to be entered in base32.

  • 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.

Seed display security mode

In the "secure" mode that can be selected on top of the app, the seed value will not be shown in the text field and will be automatically removed on every successful burn operation.

TOKEN2 TOTP+

Token2 TOTP+ is an app that combines a regular TOTP mobile authenticator app with an NFC burner app allowing to enroll TOTP profiles and copy them over to Token2 programmable hardware tokens. Any TOTP profile that was added to TOTP+ app can be instantly transferred over to a programmable token by touching the "burn" icon of the profile.

TOTP+ will store the TOTP profiles in iCloud Keychain, so when you move your iCloud account to another device, you the profiles will be restored on the new device automatically. This is why we recommend using the app only if your iCloud account is protected with two-factor authentication

Important! Do not use this app as a production TOTP mobile authenticator as the seeds are possible to be cloned, which may theoretically introduce a risk (although a minor one). The main use case is to test and compare the OTP with the hardware token generated OTPs.
