I need help. I received a new ColdCard Q which I set up successfully with a Nunchuk wallet. I'd like to create a separate wallet for my son. If I create a passphrase on top of my original seed phrase, can I just use that to set up a new wallet in Nunchuk? I am hoping while I have the passphrase active on my ColdCard, Nunchuk will treat it as if it is a new ColdCard signer.

Will this work, I can't seem to find any tutorials on this kind of set up.

Thanks 🫡

Yes. A passphrase added to your seed phrase becomes a completely new wallet.

Nunchuck knows nothing about how your wallet or private keys are created so from its perspective, it's an all new wallet you are setting up, unrelated to your other one.

Also, Nunchuck does not know anything about your device. So each time you interact between the two, you could be using brand new Cold Cards every time. So yes, Nunchuck will treat your Coldcard Q with passphrase as a brand new device because it never assumes you are using the same device.

Remember, the seed phrase (and passphrase) is your bitcoin. The ColdCard is expendable and electronics cannot be made to be robust, so your MASTER copy of your wallet must be physical and robust. Your backup IS your master.

This is the confirmation of my thoughts I needed. Thank you. And yes of course I have a steel plate backup. 🫡

Thanks Jor I appreciate the help...

BIP85 would probably be a better way to go.

After reading up on BIP85, it definitely seems to be a valid path to my desired set up but why is it better?

Okay reading more about BIP85 and that does seem to be the better option. Thanks for pointing me in the correct direction. 🫡
