Looking for Best Practices for Integrating Web3Auth with a React App?

Help - Plug n Play
1

Hey everyone

I am currently working on a dApp built in React and exploring Web3Auth for seamless wallet login. I have read through the docs and love how it simplifies Web3 onboarding using social logins and non-custodial key management. Huge props to the team!

That said, I wanted to ask the community:
What are some best practices or potential pitfalls to keep in mind when integrating Web3Auth with a React frontend: ??

Specifically…, I am curious about:

Managing session persistence across browser refreshes

Handling user state securely post-login

Any tips on customizing the login UI for better UX

Also, if anyone has experience using Web3Auth with other auth libraries like Firebase Auth or Supabase…, I would love to hear how you handled conflicts (if any). I have also gone through this https://web3auth.io/docs/connect-blockchain/evm/optimism/react-nativesap fico training in chennai but still need some more guidance.

Appreciate any insights or sample repo links.

Thanks in advance !!

Hi Marcos, thanks for your thoughtful questions and the kind words! You’re on the right track with Web3Auth for React. Here’s a summary of best practices and tips based on your queries and current community knowledge:

SDK & Platform Details:

1. Session Persistence Across Browser Refreshes

  • Web3Auth automatically persists user sessions using browser storage (localStorage/sessionStorage). On refresh, the SDK attempts to restore the session.
  • Best Practice: Use the useWeb3Auth hook or context to check the authentication state on mount. Example:
    const { isAuthenticated, user } = useWeb3Auth();
useEffect(() => {
  if (isAuthenticated) {
    // Restore user session logic here
  }
}, [isAuthenticated]);
  • Pitfall: If you clear browser storage or run in incognito mode, sessions may not persist.

2. Handling User State Securely Post-Login

  • Store only non-sensitive user info (e.g., wallet address, display name) in your app state.
  • For sensitive actions, always re-validate the session with Web3Auth before proceeding.
  • If you use additional auth libraries (like Firebase), avoid storing private keys or tokens in Redux or other global stores.

3. Customizing the Login UI for Better UX

  • Web3Auth Modal SDK supports whitelabeling and customization.
  • You can:
    • Change the modal theme, colors, and logos.
    • Hide or reorder login providers.
    • Use modalConfig in your Web3Auth options for granular control.
  • Example:
    const web3AuthOptions = {
  clientId: "...",
  web3AuthNetwork: "...",
  modalConfig: {
    theme: "dark",
    appLogo: "your-logo-url",
    // ...other customizations
  }
};

4. Integrating with Other Auth Libraries (e.g., Firebase, Supabase)

  • Potential Conflicts: Both Web3Auth and other libraries may try to manage session state or user context.
  • Best Practice: Decide on a single source of truth for authentication. If you need both:
    • Use Web3Auth for wallet management and blockchain actions.
    • Use Firebase/Supabase for backend auth and user management.
    • Sync user states by linking wallet addresses to your backend user records.
  • Community Example: Forum: Using Web3Auth with Firebase (example link, check for similar discussions).
