Login with Blockchain using one time nonce

In the Ethereum context, signing a message allows us to verify that a piece of data was signed by a specific account, in other terms, it's a way to prove to a smart contract/human that an account approved a message. Signing a message with a private or public key does not require interacting with the Ethereum network.
