Moralis.authenticate() and web3.eth.personal.sign

[kyawthet]

Hello

What is the difference between web3.eth.personal.sign and Moralis.authenticate()?
Is it possible to authenticate using only web3.eth.personal.sign?
And is Moralis.authenticate() personal_sign or eth_sign ?

authenticate uses personal sign to sign the message

Thanks a lot @cryptokid for swift reply.
