How can I unlock my account

Question

I cannot unlock my account.

I decrypted my account from encrypted accoun, and want to unlock it to deploy contract.

However, I am getting this error,

 Node error: {"code":-32000,"message":"could not decrypt key with given passphrase"

This is my web3 code.

const decryptEtherAccount = await web3.eth.accounts.decrypt(etherAccount,'test!')
web3.eth.defaultAccount = await decryptEtherAccount.address
const account = await web3.eth.getAccounts()
const address = await web3.eth.personal.unlockAccount(account[0], decryptEtherAccount.privateKey, 1000)
console.log(address)

Are there any problems of my code?

Also, could we unlock account, not node?

Answer 1

We can unlock account only for the account that made from web3.eth.personal.newAccount(password, [callback].

If your address is made by in any other way, you don't have to unlock it.

You need your privatekey.
