So you want to backup your seed phrase.
Why is this important?
Your recovery seed is the most important aspect of maintaining ownership of your cryptocurrencies.
If you lose (or forget) this seed phrase you won’t be able to restore your wallet if you lose your phone or hardware wallet.
How do you backup your seed phrase?
Most people write it on a piece of paper, and store it in a safe or deposit box.
Is this really safe enough though? We don’t think so.
Here’s what we recommend:
Open your laptop and create a file with your 12 words seed phrase
Encrypt this text file using the instructions below
Place these files into a cloud storage or hardware device (we recommend using cloud services as there is always a chance to lose your HDD or USB stick).
So in order to maximize security of your seed phrase you would need to encrypt it using your Windows computer:
Windows 10, 8 and 7:
Once the software is installed, please follow these steps to encrypt your file with 12 words phrase:
Right click on the file to be encrypted.
2. Select “7-Zip” then “Add to archive…”
3. In the Add to Archive window change the name of the archive you wish to create.
4. Change the Archive format to “Zip”.
5. Change the Encryption Method to “AES-256”.
There is a trade-off between using AES-256 and ZipCrypto. AES-256 is proven much more secure than ZipCrypto, but if you select AES-256 the recipient of the zip file may have to install 7-zip or another zip program to read the file contents. Selecting ZipCrypto may allow users to open the zip file in Windows without a zip program, but it does not provide adequate protection against attackers with modern cracking tools.
It is strongly recommended to use AES-256 to protect sensitive and confidential data.
6. Enter a Password. Use a strong password with at least 8 characters containing upper and lowercase letters, and a minimum of one number.
7. Select “Ok” to create the encrypted archive file. The new archive file will be located in the same folder as the original.
Key don’t do’s:
Don’t store your seed phrase on a note taking app
Don't use screenshots of the seed phrase cause it can easily be accessed by someone
Don't store one and the only copy of your phrase, you'd better make some copies just in case
