I am creating a React Native app for social login with web3Auth, such as below.

I notice there are 4 producs, PnP, MPC Core Kit, Single Factor Auth, Infra SDKs. Is PnP the right choice?

Hi Vic, great question! You’re exploring which Web3Auth SDK to use for a React Native app focused on social login. Here’s a concise breakdown to help you decide:

Web3Auth SDK Options Overview

  1. Plug and Play (PnP) SDK

    • Best for: Fastest integration, out-of-the-box social login, minimal custom logic.
    • How it works: Reconstructs the user’s private key on the device after login (using Shamir Secret Sharing).
    • Docs: PnP React Native SDK

  2. MPC Core Kit SDK

    • Best for: Advanced security (private key is never reconstructed), enterprise use, multi-factor authentication, and custom recovery.
    • How it works: Uses Multi-Party Computation (MPC) and Threshold Signature Scheme (TSS); only signatures are generated, not the private key itself.
    • Docs: MPC Core Kit React Native SDK
    • Note: Requires Enterprise plan, but you can test on the sapphire_devnet.

  3. Single Factor Auth (SFA) SDK

    • Best for: Lightweight, single-factor flows, and custom UI.
    • Docs: SFA SDK

  4. Infra SDKs

    • Best for: Backend or custom infrastructure integrations.

Which Should You Use?

  • For most social login use-cases in React Native, the Plug and Play (PnP) SDK is the recommended and simplest choice.

    • It provides a modal UI and supports all major social login providers.
    • It’s ideal if you want to replicate flows like the one in the YouTube video you shared.

  • If you need advanced security (never reconstructing the private key, multi-factor authentication, or custom recovery flows), consider the MPC Core Kit SDK.

    • This is more complex and typically used by enterprise teams.

Resources

Summary:

  • For a standard social login flow in React Native, go with the Plug and Play (PnP) SDK.
  • If you need enterprise-grade security features, explore the MPC Core Kit SDK.

Let me know if you have specific requirements (like custom UI, MFA, or exportability), and I can help you further narrow down the choice!
