I just wrote them on a post it note stuck on my computer.

For you steelplatefags, how do you stamp it in properly? I used a hammer and bit set but for a lot of letters i had to hammer in several times and it came out shitty. I used 2.5mm bits to fit the 12 seed phrase on one 24 word titanium card

I just used 1mm thick aluminum sheet and a regular ballpoint pen. Also the seed words are encrypted using a particular text from a book that can be easily found online, so even if someone finds them they can't do anything with them if they don't know the exact book used to encrypt the words.

I hope you don't store your seed words in plaintext, right anon?

I built a Minecraft level where each word is placed around the map in a specific secret location. The map file is encrypted but even if someone got ahold of it there are various locations and traps within the level that will throw an intruder off the scent.

What is a seed phrase? I have all my Eth on KuCoin.

I keep seeds stored in a dungeon. Each dungeon is guarded by a powerful monster which can only be slain with a weapon from said dungeon.

I keep mine in an online article about Hunter Biden that is harmful to Joe Biden's bid for president.
Nobody will ever see it, big tech will make sure of it.

I have my seed phrase stored on my NFC implant. I haven't found a good way to encrypt the data yet, so I always have to come up with some excuse when people ask me about my implant (I won't let anyone scan it obviously). Any advice on encryption?

>>23316716
You're probably joking but I like this idea except for the fact that Minecraft maps are built on spaghetti code, glitch-prone, and large.

I don't have any seed words btw, I just leave everything on Coinbase Pro.

>>23316716
What if the file is corrupted or your hard drive died?
I guess you can make a backup on cloud but I don't think it's extremely reliable

Just keep it on Binance, I love the risk and adrenaline

>>23316584
That passphrase only provides a little bit of security by obscurity. Any tech guy could brute force it in a few minutes of computation:
https://blog.bitmex.com/call-me-ishmael/
https://en.wikipedia.org/wiki/Dictionary_attack

>>23319055
lol you can't even realistically do a dictionary attack on a 6 word passphrase let alone 24

>>23316240
I just have multiple computers running multiple bots that brute force seed phrases 24/7... already scored 10 accounts and up 20 eth lol..............

>>23316240
I say them in my head every day while brushing my teeth.

Tattoos. Half of them are red herrings.

>>23319296
OP said he copied the passphrase that encrypts his seed from a book.
That is a low entropy passphrase that can be cracked.
It could be cracked by a specialist like Wallet Recovery Services.
It could be cracked by the forensic lab of a nation state. They do dictionary attacks at 1 trillion guesses per second with libraries full of books, different combinations, lengths, permutations.
If you generate a random passphrase with 128+ bits of entropy it will be effectively impossible to crack.

>>23316240
I have them in keepass

>>23316716
>Creeper blows up part of your seed
What now?

>>23316240
Isn't the whole point of seed words to write a short story with them so you never forget?

>>23319618
>That is a low entropy passphrase that can be cracked
depends on the size
basically a word is like 500k strong roughly
so 2 words are 500k^2 = 250 billion
6 words are 1.5E34 combinations that's a bitch ass big number.

>>23319618
>1 trillion guesses per second
so like it would only take 317097919837645 years give or take?

I sent my seedphrase to Metamask support email so whenever I forget it I could reach them and ask for a backup.

>>23316240
Tatto the phrase on my penis

>>23319839
They're not random guesses though.
If OP selected words or phrases from a book, it significantly narrows the search space and lowers the entropy.

6 words randomly selected from the BIP39 wordlist is only 66 bits of entropy.

> In 2002, distributed.net cracked a 64-bit key in 4 years, 9 months, and 23 days.
That was 18 years ago. Nowadays nation states probably have ridiculous hardware clusters that could crack 64 bits of entropy in a couple days.

What if you want to quickly sell and need your seed? You gonna drive to 2 different states to find them?

>>23316716
You can literally get those words straight off the save file, but it was probably already sent to some telemetry logging database at Microsoft/Mojang by now.

>>23316240
Used an offline computer running TailsOS (only runs in memory) and encrypted the list with AES256 and a strong password. Moved it to a flash drive, then to my main computer as well as any cloud storage I want. Extremely convenient, and more secure than typical physical solutions like plates or notes. Will burn the file to a CD as well to avoid EMP attacks.

>>23320332
Imagine having to sound like a security fag this hard

>>23316288
This is me

>>23320332
Arguably less secure than paper/plates. The flash drive could have malware that captured the passphrase and transferred it to your main computer.
This is why it's recommended to only export data from an airgapped machine using a QR code or handwriting.
If you go the handwriting route, you could also write down the SHA256sum of the data.
When you manually import the data you can take the SHA236sum again to make sure you didn't make any typos.

>>23320086
>BIP39 wordlist
yeah that's only 2048 words
>If OP selected words or phrases from a book
no that was not exactly my understanding not how you use books to encrypt. the words are seed words and random, the ciphertext is the location of the word in a particular book. since there are only like 120 million books out there give or take that system would be cracked by my laptop in a few minutes.
but 6 english words random is fucking impossible to crack in the amount of time our entire universe has existed with all the computing capacity of this planet.

>>23320592
Yeah that was a concern, the flash drive was recently formatted and was formatted multiple times before this use case plus I never plugged it in while Windows was running, but I should have found a way to format it from Tails to go the extra mile there. I also have a wallet passphrase which certainly adds security.

Not too late to re-do it though, considering its currently empty. Although people say to stay away from digital solutions like this for the risks you brought up and more, I have to say that if crypto ever went mainstream and thieves began understanding what random lists of words were doing in people's houses I would feel much more secure having a carefully set up encrypted file over anything physical.

>>23320865
meh formatting the drive does jack all to firmware nasties. and it won't even overwrite the drive relocator map and information sectors.

>>23320865
>I would feel much more secure having a carefully set up encrypted file over anything physical.
you need to learn about bip38 paper wallets nigga!

>>23316716

Bitch I got a fully modded Skyrim VR with each word in one of 24 books scattered throughout the map, a full mint condition untouched Valve Index, and it is sealed in a heavy duty trunk buried 6 ft below the earth in the back woods of my home.

My son will get the GPS coordinates on the day that I die.

So where do you put your money?
Yeah seed phrase but which app?

>>23316240
fucking cringy faggot. just buy a military grade usb stick with encryption. f normies

>>23320917
bip38 uses scrypt for key derivation which means it takes roughly 1 to 5 seconds for a computer (some badass crazy monster server versus a home pc) to try a single passphrase. it's also pretty memory intensive so no asics most likely.
now if you use 20+ char passphrase or a random sentence you memorize you get 900 quintillion years of security. universe is only 13 billion years old btw.

Do you put it in metamask and keep your seed phrase safe?

They're stored on plates but the plate is stored inside a hollowed out copy of infinite jest, which was dipped in rubber, wrapped in tinfoil, and welded inside of a solid steel box. this box is inside of a water proof plastic container thats coated in flex seal. all of this is at high elevation in the pond on my grandmas property bolted to the little dock thingy supports under water. my grandma watches over this pond from her porch during the day with her shotgun and at night has motion detected alarms rigged. she's already taken out two IDF agents, so I'm considering other locations.

Posted it to a guy in discord he said he would keep it safe for me.

Honestly pen and paper is more secure than anything else, but in the 0.0000000000000001% chance your home got burgled and the burglars took the piece of paper and knew what a seed phrase is and managed to get to your wallet before you, you could just store the last 3 or 4 words somewhere digital like a passworded text file on your google drive (or even memorise them)

>>23319618
Do wallets even allow that many phrases (or attempts? don't they have built in lockouts after so many failed attempts)?

i stamped it into a mini steel plate, then put it inside the enclosure of a madden 96 Nintendo 64 cartridge, then plugged that into my n64 which is boxed up inside the packaging of my microwave.

my other backup is a modded super mario 64 rom lakitu's camera lense texture has been replaced with a qr code of my seed phrase, as a bonus, the qr code can only be read if you use an emulator which allows you to disable texture filtering

>>23316638
This is fine faggot. Throw it in a rar labeled family pics and hide it in a jpg for good measure.

this but unironically

I named my S.T.A.L.K.E.R stashes after them.
I also keep part of the phrases on bookmarks in books at my parents house

>>23316716
I bump this thread just because of that awesome idea.

>>23316240
google docs kek

honestly just wrote the whole phrase in the back of a book i left at my mom's house

>>23319798
Yes. I wrote them out in a crudely drawn piece of paper I keep both hidden in my car and in my in my house in a drawer. I just made it look like a toddler wrote it out. I dont expect the person breaking into my car or house to be looking for my fucking seed phrases lol.

>>23319454

>>23321631
rar files may be encrypted but the key derivation algo is extremely weak compared to say bip38

>>23316240
I had a paper backup which I memorized and checked to see if I remembered properly every now and then. Eventually I got confident enough that I burned the paper and now the words are only inside my head. Never typing or writing them on anything but an offline hardware wallet

I carved the words into a rock and lodged it in my rectum

>>23316240
It's on a piece of paper in a shoebox in my closet. People don't know that it's an xmr seed with 300k in it lol

>>23316240
i have several pieces of paper in multiple locations with 1000 words typed on it i only have to remember the first word and every other word after until i get all 24 and that is the entire seed phrase so in case someone ever finds it they wont be able to just use it

>>23319618
>passphrase
his stamped passphrase may just be numbers, the books page number line number and word number, from an unknown book good luck with that

>>23320068
That’s genius, no one will ever see it

>>23321341
Wtf this is the smartest approach I’ve seen yet in 8+ years

I modded a version of the original mario for NES. In specific locations, the tiles are changed to spell out a phrase on the screen. you need to basically complete the entire game to get the full code. My usual time is about 45 minutes.

You could steal the source code but would not be able to determine where the phrases are as i simply changed the tile animations. sure you could look for differences in tile sets, but i randomized them throughout the entire game. maybe you could write some kind of super AI program to try and figure it out.

I have hard copies and big weapons

>>23324655
Hope you don't get a concussion anytime soon.

Paper.

Too bad fags I can just remote view back to the time when you first made/saw the phrase, write it down, then astral project to spiritual sex with your Mom.

>>23316240
Wrote my keys in HolyC and saved it on an offline pc that runs TempleOS

What about encrypting a txt file with my keys and uploading that to drive?

I literally forgot most of them...

I just have the words on a book on my native language and coded the location within the bigass book.

>>23316240
Bought a common and easy to replace dictionary, recorded every page number and how many words in on each page the seed word is. Have that saved in writing, on a usb stick in a tails vault, in writing at parents place and on cloud.

I just wrote my seed words in the bible and put it in my bookshelf.
Ain't no robber gonna check that.

>How do you guys keep your seed words safe?

I have the private keys for my Ethereum wallets in a text file on my desktop that I just copy paste into the web version of MyEtherWallet when I want to do a transaction. The private keys contain ~30k LINK and 500 ETH.

I have my 11 closest friends a word to remember. If I ever need my seed words, I will just ask my friends

>>23330860
as you say but it is not irrelevant if your words come from 2048 piece bip39 dictionary or the english dictionary which has about 500k words you can use (plus brand names and made up fantasy names and so on)

>>23331545
it's only if we had multisig smart contracts with fallback timelocked decision branches... why did nobody thought of this in 2010? oh wait they actually did.

is ledger nano s safe?

>>23331685
not particularly your security depends on entirely outside factors and practices that don't actually involve the ledger device aside from it being an extra physical attack vector using the standard practice recommendations.

>>23320228
If you use a hardware wallet you only need the phrase for recovery

>>23331848
and that's the problem with them, you have a potential to get your crypto stolen if you lose custody of the device or lose custody of a piece of paper.

meanwhile if you use a bip38 paper wallet with a decent but memorably passphrase you can have multiple physical and digital copies with absolutely no risk of getting your bitcoins stolen or losing it by accident (assuming you diversified the storage locations).
an other thing to note: you only really have to store the private key part because it generate the pubkey and address this gives you more privacy if you say upload it to your gmail account.

How are you guys stamping these into metal?
do they sell kits online

Thoughts on having the 24 word seed phrase and simply flipping two of your favourite numbers. So for example if you like 4 and 9 flipping/switching those two words with one another.

>>23334107
yeah great idea... replace gazzillion times trillions of years of security trying to guess 24 words with 5 minutes (which it takes to remove any lock you put on one of these) and also pay for the privilege to do something so stupid

just do some math man...
let's say every person including newborn babies have a 12 (not 24 which is today standard) seed word wallet on earth.
so that's like one in 6E29 for a random try to be successful. so he can try for arguments sake 1 million per sec (which is totally impossible for a loser without access to supercomputers but whatever)
it would take him statistically 19025875190258751 years to get a single hit.

unironically

I bought a psx and made football teams with the players names making up my seed phrases

>>23337213
Have you saved them on a memory card?

>>23319055
I actually use a book cipher, meaning that the end result looks like this: 7,15,4,3,4,6,8,5,9,5,14,6...

First number is the page number, second is the word number, and third is the letter used from that word. I think that without knowing the exact text used for encryption it should be pretty much impossible to decipher it, right?

>>23319618
It's not a passphrase, every letter from the seed words is replaced by two or three numbers, the page number, the word number and the letter from that word. So if I need to use the letter Y I'll just look in a book/ text for a word like yellow, hungry, trippy, yearn and write down the page #, the word # and the letter #.

Takes a while to encrypt and decipher it but it's pretty safe imo

>>23338614
no it would be under 5 minutes for this setup >>23319618
remember there are only 130 million books in existence that is like using a 6 character password

explain why and I'd stop thinking that you're full of shit

>>23338850
it's right there in that guys post. if your adversary has all available books scanned and indexed his difficulty of breaking your ""cypher"" is akin to the difficulty of breaking a 6 character password.
this is so fucking weak it's retarded. unless you have a book that you are sure never been scanned but then you risk not having access to it anytime anywhere.

>>23316716
Why not just make the blocks spell out the seed phrase, but put them in different maps. You would know the correct ordering, but other people might be completely clueless. You could also throw some red herrings in there, or know that only the blue words (or whatever color) are the right words
