How to verify MetaMask account holder is the real owner of the address?
I recently saw this post and tried it immediately, unfortunately, I am not getting the right result from the server. I think it has something to do with the hashing algorithm sha3, but I am not sure. Could anyone please update the solution? Thank you!

I think this is what you are asking for...
Using Web3.js 1.0 and Metamask:
Create a signature for a message:
Recover the address for a message + signature:
You should see that
signing_address
will matchaccounts[0]
if you are using the same message and signature across the board.
