Exactly what I was looking for, set-up and full use case.

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

Beautiful explanations your channel should have a 100 k subs

[jeffmcclure]

Excellent explanation and demo of phasephrase. Thank you!

[Marinate]

Good vid. Glad to see you with the MK4!

Another excellent video, you explain things very well. This passphrase insertion will be made much easier with the new Coldcard Q.

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.

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 ?

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?

😅

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!

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

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!

[adyu]

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..

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.

[CanInelli]

Do the passphrase words need to be from the list of bip39? Or can I randomly choose different language words as passphrase?

[ztheach]

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?

[garrettsur]

Can we choose to use our own words for the passphrase?

[condoonsixthavenue]

Using a passphrase means that you always will need a coldcard to sign transactions?

[volodymyrmoisiuk]

I would never use bip39 words in passphrase. At least, I would avoid using only those words.
