OK, this would sound noobish but I'm interested to know how other people keep the mnemonic phrase generated by the wallet. I do have the wallets secured with a pw and backed up (still not enough to warrant a hardware wallet) but I also have the passphrases handwritten in paper (someone said be wary of printers) and stashed somewhere but I'm wondering if there's a better way to keep them.

I don't know any cryptography but I'm thinking of shuffling the words rather than writing them down in order. Like a 12x12 grid where I'd spread them out in certain patterns and then finished with filler words. Since it's no longer as straight-forward should anyone get their hands on it, I think it would finally be safer to keep digital copies of it. Any suggestions?
very interesting topic . i will convert mnemonic phrases to arabic numerals . each word as a group . each letter as a unit . such as :" good day"  it is "[7, 15,15,4][4,1,25]" the numbers are the order of letters in the alphabet . you can also assign a specific number to each letter .

i certainly prefer hard copies over digital ones. it is so much safer to have it written on a paper or even better etched on a metal or even wood rather than digitally which can be stolen or damaged.

Oh yes, thanks for reminding me about etching. I was actually interested on trying out pyrography using just a cheap lens, the seed might probably be the first one I'll burn into these plywood I have.

this is a valid concern but also someone has to be looking for it in that temp memory to find it.
imagine you see this written on a wall in the street:
Code:
0C28FCA386C7A227600B2FE50B7CAE11EC86D3BF1FBE471BE89827E19D72AA1D
it looks like random data and you may just pass it but in fact it is a private key and it may contain 1000 bitcoin!
Code:
5HueCGU8rMjxEXxiPuD5BDku4MkFqeZyd4dZ1jvhTVqvbTLvyTJ

so your malware, thief or whatever has to know you printed a private key, look for it in your printer's memory, dump that memory and find the private key and steal your coins.

I suppose the malware can simply track whether you have wallet software installed and only then it would check the printer memory? I was reading an article yesterday. Apparently even the pass phrase is not save anymore since they can just take a screenshot of the screen.

I choose two ways to save! Memory always forgets, so I choose ji.

The first way I took my pen and notebook and copied my mnemonic!

The second one is my screenshot mnemonic, and then print it out and save it!

Yes, save data on digital file are more secured. My self making secures data on my computer like this:
1. Save the mnemonic phrases on .txt file
2. Pack the file into file .rar with strong password set
3. Install Bit-Locker
4. Put that file '2' to Bit-Locker encryption '3' , set Bit-locker with password
5. Write the rar and bitlocker password on paper or some notes

"Yes, save data on digital file are more secured". Definitely NOT more secure. It actually is A LOT lot more dangerous.

By the time you were just saving the mnemonic phrases on the .txt file, if you had malware on your computer, they've already stolen your seed.

Also, that makes zero sense. Why would you risk saving your mnemonic phrases digitally if you were just going to save your password on paper in the end anyway? Why not just write your phrases on paper straight away instead of writing your zip/rar file's password?

I think there was a similar thread here yesterday. I'm keeping my phrases written on 2 pieces of paper. One of them is among my notes but it's hard to notice. Somebody would have to know what to look for to find it. The other is inside one of my books on the shelf. If somebody starts stealing my books it's going to be the end of the world anyway Cheesy

I don't really agree. I think the safest way to store your mnemonic phrase is not with a digital copy, but offline. I store it on a piece of paper, written by myself (not printed) and hidden in my house. How can someone still it? I should suffer a robbery from someone who knows what he is looking for and where to find it, a little difficult I would say... Instead, everything that's in your computer can be hacked.

Go old times.
Paper would still be best. USB's can get corrupted anytime and also your computer with just a simple virus.
While with paper you can just keep it at your house or in your wallet, physical wallet.

If ever it was stolen I dont think pickpockets will know what the hell is that. Codes like that are meant to have copies too. So you can have two or three written in some paper.

My technique is that I print 2 copies of them and store them in two different places which I am the only one who knows. A digital copy is not so safe anymore because of the presence of the hackers and malwares. Also, I recommend you to buy a ledger because it will really help you keep your assets secure in one place.

To safely secured my personal data like mnemonic phrase, login username and password, 2fa secret code, I always created a google docs. And i compressed it through winrar with a strong password and saved to my usd flash drive. Thats how i safely secured my personal data. I hope it will help you Sir.

In my opinion, this is a very dangerous way of storing the information which is necessary to access your electronic wallets. Google documents are easy to crack: due to the cloud, they are synchronized on all devices where your account is open, so accessing this information becomes much easier. I adhere to the "old school" option - I store information about passwords, secret phrases and keys "on paper" - in several notebooks, which I have access only.

First of all, don't use Windows since it has the worst security.
Antonopoulos recommend to just use the easiest (and actually has the lowest failure rate), that is simply write it on paper and keep it in somewhere safe.
Don't be overly smart he said.

Other than that, use offline linux OS to keep the soft copy if you want.

You should write a paper or store it in a safe place if you are afraid of theft. However, do not forget to put a password that you use regularly to avoid having to do it again.

I've always been a big supporter of memorizing the code and storing it on paper in several secure and safe locations.

I've also been following the idea of storing it via chip implant. The future?

You can save your mnemonic phrases in document text and keep it protect by a program like WinSesame

You could make your own sort of "encryption algorithm" just so if ever someone gets a glimpse over your seed, they wouldn't be able to steal your coins. Like, probably instead of writing your seed straight on, probably take a look at the word list and list the words above or under your seed words instead. This example is definitely not a good way to do it, but I hope you get the idea.

That's exactly what I thought of first but considering I don't know of a good way to do that, it'd probably very easy for them to find out. Which is why I think I'll end up with something more visual like the pattern key I use on my phone.

Since other posters already suggested good ideas, I'd like to share one sort of "unorthodox" way of storing your mnemonic phrases.

Memorize it. Yes, you heard that right. A 12-word recovery seed is a lot easier to memorize that most people thought(though memorizing 24-word seed is still possible, just significantly harder). But I understand that this is definitely not for everyone.

As someone who routinely forget passwords for sites and ending up having to have a reset request sent, this is definitely not for me.  Sad

they also set up a completely different 12th(24th) word(as a surrogate) with just a few satoshi's on that seed phrase incase ever physically aproached by someone with a hammer or gun demanding the whole 12(24) words... you simply give the 11(23) normal words. plus the surrogate 12th(24th) word to get them to leave you alone saying its all you have... knowing it would only cost you a few lost sats to be left alone

OK I'm noob when it comes to the tech side and I've only used Electrum and just go with standard setting and the seed it generates. Are you referring to the optional seed extension or are you talking about making a dummy wallet using the same seed as the main wallet save for the last word so that it would be easy for to memorize?

You shuffling them? Really, I mean that could just make it worst if you dont remember the order later on and somewhere you will have to put the passphrase in line to capture it later on. I dont really think all these majors are necessary to make it more complicated in the first place. Just printing it and keeping it in your house safe somewhere can do the job mate! The printing or writing it down the old way is always golden one. Believe me it can stay untouched in your closet forever until storm doesn't fly away with your house. To be frank people just make it look like very sophisticated and it is not in the first place. Putting it on different storage's (digital one) can have risk of getting hacked, synched, destroyed etc. Better write it!

This is very wrong because you can easily forget it

Hence the reason why I said "this is definitely not for everyone".
