2. Why is backing up the mnemonic phrase and private key so important?

Mnemonic Phrase and Private Key are the core of the Web3 wallet. The mnemonic phrase usually consists of 12 to 24 English words and serves as an important "recovery password" for the wallet. Whether you need to reinstall the wallet, change to a new phone, or forget the wallet password, you can restore the wallet and its assets with just the mnemonic phrase. The private key is a string of characters corresponding to the public key; possessing the private key means having supreme authority over that wallet. Therefore, losing either the mnemonic phrase or the private key may result in the inability to recover assets, and in severe cases, even the risk of permanent loss.

In simple terms, the mnemonic phrase and private key mean:

1. Control over asset security: Only by mastering the mnemonic phrase or private key do you truly have absolute control over your assets.

2. Recovery and backup functionality: The mnemonic phrase is the only recovery method; without it, wallet assets may face irretrievable risks.

3. Backup methods for the mnemonic phrase and private key in the OKX Web3 wallet

1. Wallet Backup

The OKX Web3 wallet offers various methods for backing up the mnemonic phrase and private key, which are simple to use and highly secure. Here are two recommended backup methods:

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

Cloud backup is currently one of the most convenient and secure methods. By binding your cloud storage service, you can quickly restore your wallet in case of device damage or replacement.

Steps:

Open the Web3 wallet, click the "Full Function" icon at the top left of the page, and find [Wallet Backup].
In [Cloud Backup], select your storage service (such as iCloud, Google Drive, or Huawei Cloud), verify the wallet password, and set a backup password.
Click [Backup Now] to complete the backup.

Notes:

Cloud backup requires binding to a cloud service account, so please ensure the security of the cloud service used and properly save the account password.
Cloud backup files cannot be directly used for wallet transactions and must be combined with password verification for recovery.

Method 2: Physical Backup (Handwriting the Mnemonic Phrase)

Physical backup is the preferred choice for many security-conscious users. By handwriting the mnemonic phrase and storing it in a paper medium or offline storage device, you can avoid network attacks or data leaks.

Steps:

Open the Web3 wallet, click [Wallet Backup], and select [Mnemonic Phrase Backup].
Manually write down the 12 mnemonic words displayed on the screen, recording and checking them in order.
Store the written mnemonic phrase in a secure place, such as a bank safe or fireproof safe.

Suggestions:

Never take photos of the mnemonic phrase or store it on electronic devices to prevent asset loss due to device loss or leaks.
When writing down the mnemonic phrase, it is recommended to prepare two backups and store them in different locations.

2. Private Key Backup

Private key backup can be done through handwriting or cloud synchronization, with methods similar to mnemonic phrase backup. Be sure to ensure that the chosen backup method can completely save the file and verify the last 6 characters of the private key to confirm the backup is correct.

4. Frequently Asked Questions

1. If I forget the mnemonic phrase or private key, can I recover my assets?

Answer: No, you cannot recover them. The nature of the Web3 wallet is that users have complete control over their data; no platform has the obligation or ability to save your mnemonic phrase or private key. Therefore, backup is the only way to recover assets, so please remember and keep them safe.

2. How is security guaranteed after backup?

Answer: Choosing offline backup will avoid most hacker risks, but you still need to guard against consequences caused by accidental damage or loss. It is recommended to store the mnemonic phrase in multiple places and regularly check its integrity.
