Detailed explanation of the uses of a mnemonic passphrase (private key)
When you apply for a new account in the Wallet, you can receive a set of mnemonic keywords:
As the red mosaic part shown above, the mnemonic passphrase is a string of English words.
This string of words is important. Please do not reveal parts or all of it to anyone, and please do not forget or lose your mnemonic keywords.
This is an important private key to store your account information. When you login to your account with another device or accidentally lose your account password or account information, the private key can help you retrieve all of it.
Usage method (to retrieve all your account information or login with another computer):
After selecting “New” on the login page, check “Import Account” on the new page and input your main account mnemonic words. The new account can retrieve all your original account information.
