Crypto Security How-to's
You should remove all traces of temporary seed phrase backups.
November 15 2021
You should not keep any temporary paper copies of your crypto wallet seed phrase.
The Vault12 Digital Vault is perfect for permanently and safely storing your seed phrase backup.
Disposing of your temporary paper seed phrase is easy, but the details are very important.
You could dispose of it by burning it in your kitchen, and then flushing the ashes.
You could dispose of it by erasing, shredding, and then flushing the pieces.
Remember that your wallet seed phrase allows access to your crypto
By now, you know that your crypto wallet seed phrase is the most important thing to protect in order to guard your crypto assets. You have read about the need to use randomness to generate your seed phrase, and then how important it is to back it up to ensure that it is not lost or stolen. In this article, we will assume that you have already decided on which wallet to use, how to generate your seed phrase, and how to back it up. With your wallet set up and your seed phrase safely and permanently backed up, now you find yourself with a piece of paper that holds a "spare copy" of your seed phrase scrawled on it. How should you dispose of that precious piece of paper?
Why would you have a paper copy of your seed phrase?
You probably ended up with that piece of paper containing your seed phrase as a result of your seed phrase generation and/or wallet setup steps. Until you are sure that your wallet configuration is complete, and your permanent seed phrase backup is complete, you likely wrote down your seed phrase on paper along the way.
If you generated your seed words incrementally with dice, you likely calculated them one by one, capturing each one on paper after it was chosen.
Similarly, if you let a crypto wallet choose your seed phrase for you, you likely wrote it down in order to confirm the words back to the wallet during the configuration process. In any case, you probably did not transcribe each word directly into permanent storage the instant that it was generated - you wrote it down offline, on paper, in order to have a copy to use to help you complete the steps of saving it to its permanent storage medium. Then you saved your seed phrase to a permanent medium such as your Vault12 Digital Vault, a steel card, or a limited-access, backed-up encrypted file. You might even have chosen to use two of those forms of secure, permanent backup.
Congratulations! But now you also have this extra piece of paper that you don't need - and it would be silly to leave it lying around waiting to be stolen, or to just throw it into your trash can.
Planning to destroy your temporary seed phrase copy
You need a foolproof way to destroy the now-unnecessary, temporary paper copy of your wallet seed phase, such that it can never be reconstructed. Here are some things to keep in mind as you plan to destroy it:
- Don't put the task off. If you do not keep the temporary copy in a high-security safe until it is destroyed, every moment that it remains readable holds some risk that you could misplace it, or that it could be otherwise accessed. Properly disposing of it is not hard to do, and it does not take long - finish the task.
- Meanwhile, be aware of cameras that could record the seed phase from the paper. Your smartphone, laptop, tablet, or security camera could all capture an image of your seed phrase without your realizing it. We have all become so accustomed to cameras around us all of the time, especially when they are part of our home security system, that we lose our awareness of what is being recorded. Don't take the chance of accidental image capture.
- If you wrote down the seed phrase on a pad of paper, ensure that the page below the one that you wrote on does not have impressions that could be used to detect and reconstruct the words. Tap into your spy novel knowledge to imagine that possibility! If necessary, destroy the page underneath as well to remove all traces.
- Be absolutely sure that you did not make any errors in backing up your seed phrase to permanent storage.
Now you are ready.
Option #1: Destroy your seed phrase copy with fire and water
For all activities related to fire, you should of course carefully take appropriate safety precautions.
It is possible to burn your seed phrase outdoors, but we recommend doing it indoors, since indoor space is more controllable. (Outdoors, you may be more conspicuous, the paper could blow away partially-burned, or worst of all, you could accidentally start a larger fire.)
Indoors, you have a ready-made seed phrase burning area: your kitchen stove. When you are ready:
- Just in case, know where your fire extinguisher is located!
- Survey the area around the stove to ensure that there is nothing flammable.
- Turn on the ventilation fan near your stove to prevent setting off the smoke detector.
- Have a lighter handy.
- Put a metal pan that you will use to contain the burning paper onto the stove.
- Fold your seed phrase paper in half so that it makes a V-shaped "tent."
- Place the folded paper into the pan, pointy side up (as an upside-down "V") - this will allow oxygen to circulate underneath it for a complete burn.
- Carefully light the paper on fire, and wait for the flame to completely consume it.
- Wait for the paper to cool. Crumble the ashes.
- Flush the ashes down the toilet to avoid any chance of reassembly.
Option #2: Destroy your seed phrase copy by shredding and flushing
To destroy your paper seed phrase without fire:
- First, if the words are written with pencil, completely erase them.
- Shred the paper into extremely small pieces, such that even if any letters could still be read, no more than one letter would be shown on any piece. (This could be done using your hands, scissors, or a shredding machine.)
- Flush the shredded pieces down the toilet to avoid any chance of their reassembly.
