Passwordless with Web 3 and React
summary
Claims that passwords are replaced by wallets that sign login payloads, and that this works inside a React app. Demo uses connect wallet via MetaMask, public-key signed payloads and a React hook built with web3-react and ethers.js. Code lives at github.com/web3-off-demo. Flow shows a login button, wallet popup, signature of a server-provided payload, and a successful session identifier (ENS or public key). Presenter reports the demo runs and suggests a pragmatic “web2.5” migration rather than immediate decentralization.
