What Are Mnemonic Phrases?

A mnemonic phrase is an alternative representation of a plaintext private key. First introduced by the BIP39 proposal, its primary purpose is to help users remember complex private keys. Typically, a mnemonic phrase consists of 12, 15, 18, or 24 words drawn from a fixed word list. The sequence of these words is generated using a specific algorithm, so users don’t need to worry about randomly entering 12 words to create a valid address. However, if someone obtains your mnemonic phrases, they can effortlessly gain access to your assets. Therefore, after backing up your mnemonic phrases, it’s crucial to keep the following points in mind:

1. Use Physical Backup Methods
   Whenever possible, back up your mnemonic phrases on a physical medium, such as writing them down on paper or storing them in a fireproof, waterproof, and corrosion-resistant "mnemonic phrase storage box." Avoid using screenshots or photos saved on internet-connected devices to prevent hackers from stealing them.
   
   
2. Verify the Accuracy of Your Backup
   Double-check the mnemonic phrase to ensure it’s correct. Even a single incorrect word can make recovering the correct phrases extremely difficult in the future.
   
   
3. Secure Your Backup Properly
   Store your mnemonic phrases backup in a safe location, and take precautions to protect it from theft or loss.
   
   

By following these practices, you can ensure the safety of your assets and avoid unnecessary risks.
