In Electrum you can export the master key easy, but you have to disable the password first (for security reasons).

A better way is to go to the console and enter getmasterprivate(). It will prompt you for your password, and then after you enter it, display your master private key.

If I'm not mistaken the password will remain in the console history and you can see it by scrolling up with the arrow key .
If you do it manually like I wrote, there will be no trace of the password.

but I'm not worried about that and I want to go ahead with my plan.

This is commendable and I am sure, with a similar attitude and thanks to the advice of bitcointalk forum participants, you will succeed.

All the resources I follow suggest the seed phrase or mnemonics be used to create the back up for your address rather than the private keys, so would it be commendable to use the private keys instead or is it a way to protest against the status quo?

If you insist on using your private keys and intend to store actual funds there, I would suggest also keeping a back up of the seed phrase as a secondary means of recovering your address. I cannot see the downsides of that besides providing more security for your Bitcoins.

Not Your Keys, Not Your Bitcoin

Quote from: caveminer on May 05, 2022, 01:44:42 AM

_snip_

Using a single private key is not really safe and not good health for your privacy. How about you do it this way.

Instead of creating a seed phrase as suggested above, why don't you create a single seed ( 64 bytes) using the PBKDF2 function (Password Based Key Derivation Function 2). The advantage is that you wouldn't worry about discarding other generated private keys and addresses, You have an additional option to include a passphrase for the safety of your coins against theft of seed.
The difference between a single seed and your private keys is the byte difference, you don't have to worry about handling 12 or 24 seed words/phrase, you don't have to worry about master keys

is with seed words, which I refuse to use.

Why? Do you believe that seed phrases have some weakness in them? I'm struggling to think of a good reason to use a seed phrase to generate a master private key, and then discard the seed phrase and back up the master private key instead.

I want to store my bitcoin offline, and I want to engrave my 256 bit number (master private key) on metal, and not ever have to use 24 words.

If you want to engrave text on metal, I can advise you on this topic - Securing Your Seed Phrase with Washers to get acquainted with one of the options for saving text on metal. I understand that you are planning to store master key, in principle you can also do this using washers.

I know this is riskier (if I record one of the numbers wrong I couldn't recover my bitcoin),

Therefore, I can recommend that you make 2-3 copies in order to avoid mistakes and loss of access to your key.

Pay attention to how you create your wallet and the seed in Electrum. Because you have to generate a 12-word seed first, and after that you can export your master private key as witcher_sense explained. If you are doing that on a computer connected to the Internet and a device that has been online before the wallet creation and will go online again afterwards, you can't consider that as a wallet created in an offline environment. Your PC should be permanently airgapped during the wallet creation process (preferably using an open-source OS) and stay that way after it's done.

actually as long as you're using a safe wallet to store your crypto there's no problem with it, the most important is the keys so always make sure that you have all the correct letters on your phrases. Read it many times if you want to print it or engrave on metal and of course try it first if its correct to assure everything will gonna be alright.

I want to create bitcoin storage that I can keep offline and remember my private master key without having to have 24 seed words.

A master private key is a derivative of seed words, which means you need to create a wallet with these words first in order to obtain your desirable master private key. Once you have gotten your master key, you can delete seed words if you don't like them. A master private key is sufficient to recreate your wallet, so technically you don't need any words.

Create new wallet => Standard Wallet => Create a new seed => get your master key

Let's see what you are really after. I'll try to put it simple.

Private key is a key that gives you access to a single address, I guess that's what you are after.

Master key is created of generating a linked sequence of keys using the the hash of the previous private key. So if you want to recover the whole sequence of keys, you need only the fist one - the Master key.

Apologies for my ignorance, but I don't have a master key or anything to import or export, I'm stuck on the "create keystore from a master key page" and it says please enter your master public key, (xpub/ypub/zpub), and I don't have any of these.

In Electrum you can export the master key easy, but you have to disable the password first (for security reasons).

Go to wallet > Password, then type your "old" password and leave "new password" fields empty.

Then go to the View menu, open the console, in the console you write this one >

Code:

wallet.keystore.xprv

then your master key will show.

Now you can go back and set a password again.

Let me know if you need any Screenshots to help you
