Burning/programming/configuring the Molto-1-i token is done via NFC using a special burner app. We currently have iPhone, Windows and Android versions of the burner app as well as a cross-platform Python script that will allow to provision the device under Linux and macOS as well.

FAQ

Q. What is the difference between Molto-1-i and Molto-1 ?

A. Molto-1-i works with Android, Windows and iPhone apps as well as the python script . Molto-1 supports only Windows and Android apps. Additionally, Molto-1-i has PIN protection feature.

Q. How secure is the procedure of programming/seeding the Molto-1-i via NFC?

A. There is absolutely no way to retrieve the seeds anyhow from the device. However, to fully ensure security, in particular, to prevent replay attack by modifying the system time (which is a highly demanded feature to solve the time drift issues) Molto-1 can be protected by setting an NFC access password. New devices will come with a default NFC access password which can be changed immediately. To prevent brute-force attack, the devices will be reset to factory defaults after around 100 unsuccessful NFC access attempts.

Q. What if I have set an NFC access password and forgot it. Does it mean that I can no longer use Molto-1?

A. No, you can still use it by resetting to factory default. This reset will set NFC access password to default,  but the operation will also clear all TOTP profiles (seeds and settings).

Q. How long does the battery last? 

 A. Battery life depends on usage. Burning/programming operations via NFC consume a lot more power, so we must take that into account as well. As a rough estimation, if a token is used a few times per day (i.e. each profile is used once - so 10 button presses a day) and the NFC operations are not very frequent (i.e. not more than once a month) - the Molto-1 token will last for 4-5 years. 

Q. Will I lose access to the TOTP profiles when the battery is dead?

 A. Yes, but you will have enough time to prepare. Molto-1 will have a battery indicator on the display (). The indicator will show the status throughout the life of the token () . You should replace your token (and migrate the TOTP tokens by resetting the second factor on each respective service) when the indicator shows the battery level as "empty" () - you will still have a couple of months to do this.
