Practical Tips to Prevent Your Mnemonic Phrase from Being Stolen

使用硬件钱包

A hardware wallet is a physical device specifically designed to store private keys and mnemonic phrases. Compared to software wallets, hardware wallets offer higher security, as the mnemonic phrases never come into contact with the internet, thereby greatly reducing the risk of theft.

Practical Example:

If you are using a well-known hardware wallet brand such as Ledger or Trezor, make sure to store your recovery phrase in a secure place and regularly update the firmware for optimal security protection.

Regularly back up your mnemonic phrase.

Writing down the mnemonic phrase on paper and keeping it safe is an important backup method. Avoid storing the mnemonic phrase only on electronic devices, as these devices are more vulnerable to hacking.

Practical Example:

Store paper backups in secure locations (such as a safe or fireproof box), and consider distributing them in different places as a precaution.

Enable multi-factor authentication

Enable multi-factor authentication for your digital asset account to add an extra layer of security. This means that even if your mnemonic phrase is stolen, attackers will still need other authentication methods to access your account.

Practical Example:

Use applications such as Google Authenticator to generate one-time passwords, which are entered additionally each time you log in to ensure account security.

Keep the software up to date

Make sure your wallet app, operating system, and other related software are always kept up to date. Many updates not only bring new features but also fix security vulnerabilities.

Practical Example:

Regularly check for update notifications provided by the wallet, promptly download and install updates to ensure you are using the latest security technologies.

4. Be aware of phishing attacks

Stay vigilant against potential phishing attacks and ensure that the websites you visit are authentic, especially before entering your mnemonic phrase. Avoid clicking on unfamiliar links and attachments.

Practical Example:

Use a browser extension to identify suspicious websites and carefully check the URL before entering your mnemonic phrase.
