Add social login to a Web3 dApp by integrating Web3Auth OAuth providers like Google, Apple, and email, letting users create wallets and sessions without seed-phrase onboarding. It requires initializing the Web3Auth modal with your clientId and chain configuration.

MPC-based key management secures Web3 social logins by using threshold splitting to divide private keys into device, network, and optional recovery shares. This approach prevents a single point of failure while authenticating users via standard OAuth providers.

Yes, you can use Web3Auth with RainbowKit by wiring Web3Auth connectors into your RainbowKit configuration. This supports mixed onboarding flows, allowing users to choose either traditional browser wallets or social login authentication.

Web3Auth supports gas abstraction by pairing its wallet creation with account abstraction on networks like Arbitrum. This allows sponsors to cover gas fees, providing a smoother onboarding experience for users logging in via social providers.

To configure Web3Auth for Arbitrum One, you need your clientId and the correct Arbitrum chainConfig passed to the Web3Auth modal. Calling initModal then renders the social login buttons within your dApp interface.

Handle user sessions with Web3Auth by implementing login state checks, retrieving user info after authentication, and executing logout commands. This manages the dApp session lifecycle for users authenticated through social providers.
