How to Backup Your Wallet Mnemonic Phrase or Private Key?

·

Mnemonic phrases and private keys are the sole credentials for recovering your Web3 wallet. If you fail to back them up and later forget the mnemonic phrase, even remembering your wallet password won’t help restore access—your assets will be permanently lost. Therefore, we strongly recommend backing up your wallet immediately after creation.

You can back up your wallet via cloud storage or physical methods. Below are step-by-step instructions:

Wallet Backup Methods

Method 1: Cloud Backup (Using iCloud / Google Drive / Huawei Cloud)

  1. Open your Web3 wallet → Click the [Full Features] icon on the top-left → Select [Wallet Backup].
  2. Choose an unbacked wallet → Tap [Cloud Backup] → Authenticate via biometrics or wallet password → Set a cloud backup password → Click [Backup to Cloud] to complete.

Important Notes:

Method 2: Physical Backup (Manual Mnemonic Phrase Backup)

  1. Open your Web3 wallet → Click the [Full Features] icon → Select [Wallet Backup].
  2. Choose an unbacked wallet → Tap [Mnemonic Phrase] → Confirm you’re in a private space and click [I Understand][Backup Now] → Authenticate.
  3. Write down the 12-word mnemonic phrase → After copying, click [Continue] → Verify the phrase → [Complete] to finish.

Pro Tip: Ensure all 12 English words are accurately copied. Even one missing word renders the backup useless.


Private Key Backup

Private keys vary across public blockchains. Here’s how to back them up:

  1. Open your Web3 wallet → Navigate to [Wallet Backup] via the [Full Features] menu.
  2. Select an unbacked wallet → Tap [Account Name][View Private Key][Backup Now] → Choose either [iCloud Backup] or [Manual Copy] and follow the prompts.

Security Note: For manual backups, use [Secure Copy] to omit the last 6 characters of the private key. Complete these manually later to prevent exposure.

FAQ Section

Q1: Can I change my cloud backup password later?
A1: Yes, but wallets backed up with the old password will require the original password for recovery.

Q2: What if someone sees my mnemonic phrase during backup?
A2: Immediately transfer assets to a new wallet with a new phrase—never use compromised credentials.

Q3: Are private keys interchangeable across blockchains?
A3: No. Each chain (e.g., Ethereum, Solana) generates unique private keys.

Q4: How often should I update my backups?
A4: Only when creating new wallets or changing credentials. Regular backups aren’t needed for existing wallets.

Q5: Is cloud backup safer than physical?
A5: Both have risks. Cloud backups face hacking threats; physical copies can be lost/damaged. Use a combination for redundancy.
