First of all, thank you so much for your wonderful tutorial! I want to know Can I choose my passphrases in another language, for example, using French words ?
I've got the Cold Card Q and want to add a passphrase now. What I'm wondering is since it essentially creates a new wallet once you've added a passphrase, What will happen to the BTC in my current wallet? Should I move my BTC off the wallet first before setting a passphrase, then send it back to the "new" passphrased wallet? I assume you get a different set of addresses, which is why I'm scared to just "lose" my current wallet.
Yes, you need to move funds over from the original wallet, to the new "passphrased" wallet, with new addresses. The old funds will remain in the old wallet, they will not be "lost" as long as you have the seed phrase. If you need hands on guidance, check out www.secusats.com/
Question: if you’ve already set up the cold card and exported to sparrow following the creation of the sparrow wallet…can you now go back and create a pass phrase? Or will creating the pass phrase result in an entirely new wallet? 😅
Adding a passphrase will create an entirely new wallet. You would need to move funds from the old wallet to the passphrased wallet. Always do a small amount first and test spend
Another great video, keep it up! Would be great to get some background on why someone would use a Passphrase, what are the use cases? When is 12 or 24 words, 'not enough', and how would you then keep your passphrase - separate from your seed words? In other words, what problem(s) are you trying to solve with a passphrase vs. with a standard wallet setup? Thanks! Great content! SP
Yes, you would keep them separate. The main idea is to geographically separate your keys- so an attacker has to gain access to 2 things before they get your coins.
If you are utilizing the extra 6 words from Bip 39 passphrase would you want to keep the majority of the funds on that extended seed? Question 1) That way if you were forced to go to sparrow wallet by your attacker, he would only see the funds in your original seeded cold card? Sparrow would not show the the other funds sitting on your extended seed? Question 2) I will be transferring funds to my new seed from Trezor might I just keep a tiny amount on my Trezor and let them have that? As long as they do not discover the CC I should be ok? 3) and if they do have my CC then just go to sparrow with my original seed phrase? Thanks so much for all of your help. Finally 4) what lightning wallet do you like. I might try buying some non KYC from Robosats...
This is a great video, thanks! I've implemented a passphrase, verified the master fingerprint, and exported the xpub to Sparrow Wallet. Next, tested the passphrase wallet for both sending and receiving. So far so good. Here's my issue ... when I go back into the Coldcard and type in the passphrase, I can verify the correct master fingerprint in "View Identity" however, when scrolling down to Extended Master Key:, the value does not match what I had previously exported to Sparrow. Shouldn't these match exactly? This is more of an academic question, because as mentioned, I've tested the sending and receiving to this wallet. Thanks again!
It might be because you are looking at a the wrong public key. There are ZPUBS and XPUBS which are different keys. ColdCard and sparrow might be displaying different things. In Sparrow, there is a toggle to the right of your public key. Toggle that on/off and see if any of these keys Match. That might do the job? Let me know if that works 👍
Thanks for your reply ... same result, xpub displays different values on Sparrow vs. COLDCARD for this wallet, however, the master key fingerprint match on Sparrow and COLDCARD indicating that I typed in the passphrase correctly. I can also send sats to the passphrase wallet, and sign an outgoing transaction from this new wallet with my COLDCARD w/passphrase loaded. Odd ...
Perhaps when you export the public key, the COLDCARD generates a new one, sort of like when you use an address from your public key, a new receive address is used? In other words, can the private key generate multiple xpubs that point to the same wallet?
I noticed something that may be important ... looking at the 'view identity' screen on COLDCARD shows you the "Extended Master Key" which starts with xpub.... On Sparrow it merely shows xpub/zpub but the value still begins xpub... so maybe there is a difference between the Extended Master Key displayed on COLDCARD and the Extended Public Key displayed on Sparrow. I went back and that's the case for the base wallet as well ... the displayed values are different.
Hello - at 11:00 exactly a title screen says, "Make sure passphrase is loaded when exporting". Is this different than what is show/said in the video? If so, what are the steps for this? Is there a way to verify the passphrase loaded before exporting? I am new to this and am taking everything step-by-step. Thanks for your help mate!
so, wait a min... you'd have to enter passphrase everytime you have to sign a psbt? Thats painful, if the device signs out/cable disconnects. Another thing is will this seedword/passphrase combo work on every other hardware/air-gapped wallet? It should right..
Yes you do have to enter the passphrase every time. This has its pros and cons. Pro is that anyone with your ColdCard doesn’t have full set of keys. Yes the same seed + passphrase will work on most other HWW’s
This is sweet, but how would I recover this passphrase wallet on another wallet? Like completely unrelated to cold card.. What other wallets are compatible? That offer you to input the 25th word when you recover? Of all the wallets I downloaded over the years, I never see this option.
A lot of bitcoin wallets support this feature. I suggest searching the name of the wallet and “passphrase” to double check. Trezor, ledger, blue wallet, sparrow, all support it
Does adding a paraphrase always generate a new empty wallet, or is there a way to add a paraphrase to an existing wallet with funds already inside? If not, I suppose the only extra step is to move funds from the no passphrase wallet to the new passphrase wallet once imported into sparrow?
Yes, adding a passphrase always creates a new wallet. However, the original wallet with 12/24 words is unaffected and will act as normal. Yes, If you wish to move to a passphrase set up, you will need to send from the non-passphrase wallet to the pass phrase wallet
I would not use so many words for your passphrase. It is better to use only two or three words so it is simple enough to remember without having to write it down. The chances of you forgetting or losing the passphrase or having it stolen if you wrote it down somewhere are far greater then someone cracking your passphrase. if you store the passphrase only in your brain you eliminate the possibility of theft or losing the paper you wrote it down on.
I would never suggest storing a passphrase in only your head, That is just a huge risk I wouldn’t take. I would also want brute force protection in case someone does have my seed, therefore 6 words.
@@SouthernBitcoiner whatever works for you. but keep in mind there are 4 million bitcoin that have been estimated to be lost simply because people lost their seedphrase and/or passphrase. they lose the paper they wrote it on. that is by far the most common way people lose their bitcoin.

Your channel is invaluable
😊
Beautiful explanations your channel should have a 100 k subs
Thanks for the video. I am going to use 8 bip39 words to make up the paraphrase much easier than dice rolling 8 times and using the eff dictionary
thanks homie, very helpful
Glad it helped!
Exactly what I was looking for, set-up and full use case.
Good to hear it helped 💯
Hell yeah
Excellent explanation and demo of phasephrase. Thank you!
Thank you!
Cheers!
Another excellent video, you explain things very well. This passphrase insertion will be made much easier with the new Coldcard Q.
Good vid. Glad to see you with the MK4!

Yep, that is odd. The fingerprint is actually derived FROM the xpub. So that’s weird. This might be a question for the ColdCard telegram group

Is there a way to verify the passphrase loaded before exporting? I am new to this and am taking everything step-by-step. Thanks for your help mate!
Yes. Each wallet had a fingerprint. A set of some numbers and letters. For example. Aa39976 March those numbers

Yes you do have to enter the passphrase every time. This has its pros and cons. Pro is that anyone with your ColdCard doesn’t have full set of keys.
Yes the same seed + passphrase will work on most other HWW’s
Can we choose to use our own words for the passphrase?
Yes

Trezor, ledger, blue wallet, sparrow, all support it
Do the passphrase words need to be from the list of bip39? Or can I randomly choose different language words as passphrase?
It can be anything, but I highly recommend using bip39 words
Thanks man but why are the bip39 words safer compared to some other back to back random words?@@SouthernBitcoiner
@@SouthernBitcoiner why ?
Does adding a paraphrase always generate a new empty wallet, or is there a way to add a paraphrase to an existing wallet with funds already inside? If not, I suppose the only extra step is to move funds from the no passphrase wallet to the new passphrase wallet once imported into sparrow?

However, the original wallet with 12/24 words is unaffected and will act as normal.
Yes, If you wish to move to a passphrase set up, you will need to send from the non-passphrase wallet to the pass phrase wallet
Using a passphrase means that you always will need a coldcard to sign transactions?
Nope, passphrases can be used with a lot of wallets
I would never use bip39 words in passphrase. At least, I would avoid using only those words.
This is the best standard in my opinion (and ColdCard seems to agree), keep it simple.
6 x bip39 words take centuries to crack
And what is the point of having a passphrase if one uses 24 words?
Yes, you can add a passphrase onto any 24 words. But that creates a new wallet. 24 words + passphrase = wallet
I would not use so many words for your passphrase. It is better to use only two or three words so it is simple enough to remember without having to write it down.
