How to import ethereum account in web3 if I know address and private key?

.everyoneloves__top-leaderboard:empty,.everyoneloves__mid-leaderboard:empty,.everyoneloves__bot-mid-leaderboard:empty{ height:90px;width:728px;box-sizing:border-box;
}

I start ganache-gui and see lot of accounts, they have private keys and mnemonic phrase. Then I connect to this testnet with nodejs and web3 1.x.x, so my wallet.length is 0. I want to import all wallet from ganache by mnemonic phrase or better import one address using private key. Could I do this? I tried web3.eth.accounts.privateKeyToAccount(privateKey); but returns new account. How does it work? Metamask can do this just by privateKey.

Right. I also want to know how to import any account knowing its private key, as metamask does.

To access the ganache accounts, you have to do the following:

    const ganache = require('ganache-cli');

    const Web3 = require('web3');



   //ganache client running on port 7545

    var web3 = new Web3(new Web3.providers.HttpProvider('http://localhost:7545'));



    const getAccounts = async () =>{



   //To get all accounts

    let accounts = await web3.eth.getAccounts();



    //To get accounts with private key

    let account = await web3.eth.accounts.privateKeyToAccount('0x'+privateKey);

    //privateKey is the key that you get from Ganache client

    }



    getAccounts();
