This article introduces a new login method to blockchain development: A one-click, cryptographically-secure login flow using the MetaMask extension, with all data stored on our own back end. We call it: “Login with MetaMask”.
Sign messages with the private key of the current account (web3.personal.sign) When MetaMask is installed, any front-end code can get access to all these functions, and interact with the blockchain. They are called dapps or DApps (for decentralized apps–sometimes even styled “ĐApps”).
Login with MetaMask Live Demo: https://amaurym.com/login-with-metamask-demo/ Getting Started 1. Launch the demo using Docker Compose: 2. Launching the demo using Docker: 3. Start the demo using Yarn: Tests Credits This demo is published as part of the corresponding blog article: "One-Click Login with Blockchain: a MetaMask Tutorial".
This command means: Sign my message, converted from utf8 to hex, with the coinbase account (i.e. current account), and as a callback, print the signature. A MetaMask popup will appear, and if you sign it, the signed message will be printed. We will be using web3.personal.sign in our login flow.
