Sending a transaction to the smart contract and execute its method

Question

Suppose I am doing like this

myContract.methods.myMethod(123).send({from: '0xde0B295669a9FD93d5F28D9Ec85E40f4cb697BAe'}, function(error, transactionHash){ ... });

Do I need to unlock the account 0xde0B295669a9FD93d5F28D9Ec85E40f4cb697BAe to send the transaction ? If yes then what is the process to unlock this account. with Web3 1.0 I found web3.personal.unlockAccount on a topic but didn't find any documentation about this in here

Answer 1

Web3 1.0 is still beta so something might not work or are incomplete.

Here is the documentation of personal.unlockAccount.

Answer 2

When using the Mist Browser or MetaMask, you do not necccessarily have to unlock the account. They just take the transaction data, and sign a transaction for you.
