Backing up Librem Key

Is it possible to back up a Librem Key too a thumb drive?
Could that thumb drive function in place of a Librem Key until a new Librem Key is acquired?
I would like to keep a backup of my key in a safe place in case the key is lost.
Any suggestions?
Thanks All

Read the documentation, it tells you how to create keys on your computer, backup them to an external drive and export them to the Librem Key.

However, you can’t use a thumb drive as a replacement for the Librem Key, since it can’t do any crypto operations on its own, it is only for keeping a copy of the keys.

actually there is an method but not with thumdrive.
you can for example use youbikey, or nitrokey or different librem key, or other cryptocard.

keys you have to generated on computer not on card, and backed up.
so you can reimport private keys, and send them to “backup” youbikey or other card.

it have only one disadvantage, HOTP secret will be lost, so you will not able to validate PureBOOT with backup key. other things like unseal luks, email cryptography , signing core will work with spare key without the trobuble.

as @dpr said, librem key is not an thumbdrive, it’s a cryptographic smart card. and whole idea of smart card is: if you put private key there, there is no way to recover it from card.

you mean HOTP counter?

hotp works witrh 2 factors:
shared secret + ccounter
so even having 2 keys and trying to use them use alternately will not work. (oven if you program booth them with same secret.

Thanks for asking I was thinking I was the only one having problems following the manual.
