Not able to send ethers in private ethereum network

Question

I am trying to send some ethers from one account to another. I have set up the private ethereum network. This is the command I am using to send ethers:

eth.sendTransaction({from:eth.accounts[0], to:eth.accounts[1], value: web3.toWei(4, "ether")})

I am getting an authentication error. I don't know how to set authentication. Please help

Your account is locked by default due to which you are not able to make the transaction. To make the transaction, you have to first unlock the account. You can unlock the transaction using this command:

personal.unlockAccount(eth.accounts[0], "<password>")

Replace <password> with the passphrase set for that account and then send ethers:

eth.sendTransaction({from:eth.accounts[0], to:eth.accounts[1], value: web3.toWei(4, "ether")})
