What is a passphrase and what is a private key in crypto?

Once you have successfully created a crypto wallet, you will receive a wallet section, a passphrase and a private key or just a passphrase, depending on the different blockchain wallet solution platform.

Anyone who has either of these two pieces of data can immediately access the crypto assets stored in your wallet. Private key and key passphrase that you absolutely will not divulge to anyone.

What is a private key?

Define passphrase and private key

Why are there two passwords when creating a wallet, the passphrase is the private key? What is their difference? I will explain it in the simplest possible way for you to understand.

Think of the passphrase as the house key, and the private key is actually the key to every room in the family. A passphrase bears the internal private key in bold.

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).

Assuming you want to import any wallet from Apartment 1 (Apartment = passphrase) into the metamask used by Apartment 2, then you should import the private key into Apartment 2, not the passphrase (a passphrase cannot import a second passphrase).

Once you’ve saved the passphrase, you can access many wallets in it. However, if you need a wallet to import it to another location, you will need to get the private key.

So when can a passphrase be used, when can a private key be used?

Assuming you are creating this wallet from the perspective of the main wallet to store assets and not communicate much with the Dapp then you should keep the passphrase and private key carefully.

And suppose you are creating this wallet from the perspective of communicating with a lot of dapps, not storing a lot of capital, and desperately wanting to create a lot of accounts to airdrop and retrospectively, then you should create a main wallet with a lot of sub-wallets passphrase carefully.
