A mnemonic phrase can help users memorize complex private keys and manage wallets conveniently and quickly. However, if someone obtains your mnemonic phrase, it is equivalent to controlling your wallet assets and can transfer the assets in the wallet. Therefore, backing up the mnemonic phrase is very important. Here are some notes on backing up the mnemonic phrase:
1. The mnemonic phrase must be backed up when creating an imKey wallet for the first time. Because the mnemonic phrase generated by imKey cannot be viewed again later. If the mnemonic phrase is lost, the assets will be lost and cannot be retrieved.
2. When backing up the mnemonic phrase, a physical medium should be chosen, such as writing it down on paper or using a "mnemonic phrase box" that is fireproof, waterproof, and corrosion-resistant. This can avoid hackers obtaining the mnemonic phrase through network attacks and other means.
3. Ensure that the backed-up mnemonic phrase is accurate. The imKey wallet will perform secondary verification of the mnemonic phrase when created for the first time. If further verification is needed, it can only be done by resetting imKey and re-importing the mnemonic phrase.
Note: Before performing the secondary verification, please make sure that there are no assets in the wallet. Because if the backup mnemonic phrase is imported incorrectly, it will result in permanent loss of assets.
