React + Vite example using MetaMask Embedded Wallets (powered by Web3Auth) with a grouped connection that combines Auth0 and Google OAuth (both via the implicit flow). A grouped connection ensures the same user always gets the same wallet address regardless of which provider they use to sign in.
Without grouping, signing in with Google and signing in with Auth0 would produce two completely different wallet addresses for the same person.
- Node.js 20+
- npm
- A Client ID from the Dashboard
