Below, I’ll give an example to illustrate how the passphrase and private key metamask works, using many ideas that you can easily understand.

  • Since you create a new wallet entirely on the metamask, this account 1 can have both a passphrase and a private key.
  • Assuming you click the word Create Account, the metamask will create Account 2 for you, Account 2 may have its own private key (as opposed to Account 1’s private key) but the passphrase is similar to the same Account Account.
  • Since the passphrase is a collection of wallets, the private key is a unique wallet. So the first time you download the metamask to another computer, you need to import the passphrase first, not the private key (home activity first, then the private key). Door).
  • And since the passphrase was imported (it was active at home) we can only serve each room by clicking Add Account to serve the remaining room (you don’t need to save each room’s private key to be able to continue to be access account 2, 3, … according to sorting).
