Wie wird die Seed Phrase am besten gespeichert?
1. Metallplatten können verloren gehen oder gestohlen werden
2. Word-Dokumente können gelöscht oder gehackt werden
3. Passwort-Manager können gehackt werden
4. Gedächtnis – spätere Demenz
5. Verschlüsselung – Dokumente, Cloud usw.
6. Andere
7……
8……
9……
10…Wie würdest du es machen???

Passphrase. That way I don’t have to be so tough about my seedphrase
I have my seed on a Keystone Tablet Punch, hidden. Also, two encripted usb sticks
The passphrase is in my mind, never wrote it anywhere. I didn’t even spelled it out loud.
This way the seed is not that important, as long as is doesn’t get lost or stolen -

fyi, people are mentioning they are relying on their passphrase, which is easy to hack if one is motivated enough.
for instance, the guy digging up a landfil to find a harddrive would LOVE to only have a passphrase to discover to unlock his millions.
it could be argued that if no one knows you are using a passphrase, then you are safer, but that’s [security through obscurity](https://en.wikipedia.org/wiki/Security_through_obscurity), which is no security at all to a motivated opponent. But keeping a small amount in the passphrase-less wallet may fool a few thieves.

What I did was use professional permanent stealth ink / pen and wrote my seed phrases on some unimportant documents mixed in with my property deed and car titles. I put everything in a folder then used a vacuum sealer and sealed the folder making it air tight. Afterwards I took the folder to my bank and put the folder in a safety security box in my banks vault. I am the only one that knows where my seed phrase is. If someone had it right in front of them, they wouldn’t know it.

Add 2 or 3 extra words to your written down phrase. These added words could mean something to you so easy to recognise.
In other words if someone else found your phrase, they’d be looking at 26 or 27 words. The odds of them finding out which 2 or 3 are “fake” would be like winning the lottery I suspect. -

many different ways, but best imo is to encrypt the seed again or split it up, no matter if you put it on a plate, paper or even on a computer, what you can do for example, write all but 5 words in a computer document, and put the left over 5 words on a metal plate or copy on multiple papers, you can even store them in plain site, because just the 5 words alone have no use and also the computer document alone has no use, just make sure that nobody can bring those two parts ever together but you

3 Ledgers with same seed phrase. One you keep for use, the other 2 are backups in different geographical regions (only 1 needs to survive theft/destruction to have things be spendable). As a backup to catastrophic failure of all 3 Ledgers in geographically different locations, the seed phrase is on a Cryptosteel Capsule, buried somewhere.

I use an improved paper wallet method.
1. Create a name for your wallet or just a random string
2. Make some tricky sha-256 calculations, for example get sha-256 hash 666 times recursively. The result is a 64-chars hex string.
3. Go to [https://iancoleman.io/bip39/](https://iancoleman.io/bip39/) -> toggle „Show entropy details“ -> paste the hex string
4. You will get 24 words for your new wallet, transfer your money there.Pros: your backup is just a string and algorithm. Only you know how to get a wallet from this string. It’s much better than storing 12/24 widely known words.
Cons: requires some skills in step 2.

I have my seed phrase split in two and each half is kept in a steel plate – in two separate locations.
For someone to get my full phrase, they’d have to 1) figure out the location for each plate 2) figure out how to break into those locations 3) figure out where the plate is hidden at each location.
I don’t want to say there’s zero chance that someone figures out 1, 2, and 3, but I feel pretty confident about it. No digital copies have ever existed.
I also have a back up copy without the last few words at a different location, just in case.

Consider using Shamir’s Secret Shares [stamped in steel](https://blockmit.com/english/guides/diy/make-cold-wallet-washers/) and store the shares in several secure locations.
Here’s a handy app for securely generating the shares on an air gapped Ledger device:

I punched my seed on metal and store one in a security box at the bank in a different country and have one metal seed with me that I leave at home hidden. The passphrase is in my password manager incase something happens to me then my family can access both easily. I have a different passphrase for each crypto project.

There’s no single answer, it’s like asking „What’s the best car?“ Well, it depends…
Best practice is to never save it digitally, not even encrypted or a photo. That’s one rule I would always adhere to. And that also means, never type the seed in any device other than the hardware wallet itself if you need to restore or want a second device as backup.
There was recently a case of hacked Metamask wallets and the surprising thing was that many of those people who got hacked were OGs and haven’t had moved their funds or signed contracts in Metamask, so there must have been another exploit. And as it turned out, what they had in common was they saved their seed in LastPass, which got hacked and apparently the hackers were also able to decrypt the user data. ([source](https://www.reddit.com/r/Lastpass/comments/164m04m/25_million_in_crypto_stolen_from_lastpass_secure/))
Another common mistake is that people don’t use well-tested best practices to safe their seed but instead come up with their own overly complicated methods and then they end up not being able to restore or find the seed. Some guy had a large amount of Bitcoin in a wallet he lost, and the seed was saved on a Kingston IronKey thumbdrive that deletes itself after 9 wrong entries. The guy forgot the password.
Someone else had their seed hidden with his fishing lures in a shed. This too was a large amount of Bitcoin. Somehow he forgot about it, the shed later got cleaned out and years later his Bitcoin would have been worth many millions.
So yeah, user error is a serious threat.
I got 2 hardware wallets with the same seed, in case one breaks. And I got the seed split in 3 pieces in different locations (one is a bank vault). I need 2 of the 3 pieces to restore the full seed.
For me personally, this is the best tradeoff between security and convenience.
(I don’t think cryptosteel truly has much benefit over paper. It’s quite unlikely that a fire would destroy not just the seed but also both my devices in different locations at the same time.)
