Question 1

What happens when the battery dies? Are they replaceable or do you need to transfer accounts to a new key before it dies?

Accepted Answer

Hello,
The battery is not officially user replaceable but probably possible with enough skill.

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.

Question 2

can this device be used under linux ?

Accepted Answer

Hi, the device does not require a computer to get codes, however, it must be programmed initially using the NFC chip on most android and newer i-phones.  There is an app available in each phone's app store. Additionally, the Molto-1 can be programmed using a USB NFC module and the Windows-only Token2 MFC Burner app for Windows. I don't know if the MFC Burner app will run in Wine or a VM under linux.  Easiest thing to do is just program it with your phone:
