Web3Auth provides a powerful authentication system that bridges the gap between traditional Web2 and decentralized Web3 identity frameworks. It offers developers the tools needed to create secure, flexible, and user-friendly onboarding experiences while enabling seamless access to blockchain-based applications. By supporting a wide range of login methods and wallet integrations, Web3Auth helps improve user conversion rates and simplifies the user journey into the world of Web3.
Supported Authentication Methods
Web3Auth supports multiple authentication mechanisms, allowing developers to tailor the login experience to their audience—whether they are new to Web3 or experienced crypto users.
Email and SMS Login
This method enables passwordless authentication using one-time passcodes (OTP) or magic links sent via email or SMS. It’s ideal for users who may not be familiar with cryptocurrency wallets, offering a familiar and accessible entry point.
External Wallets
Users can sign in using popular third-party wallets like MetaMask, Phantom, and others compatible with WalletConnect. Developers can customize which wallets are shown through the Web3Auth Dashboard, ensuring relevance to their user base or geographic region.
Social and OAuth Login
Web3Auth integrates with numerous social identity providers, letting users log in with accounts they already use and trust. This reduces sign-up friction and is especially effective for consumer applications aiming for broad adoption.
JWT-Based Authentication
For applications with an existing authentication infrastructure, Web3Auth supports JSON Web Token (JWT) integration, including OpenID Connect (OIDC) and OAuth 2.0-compliant providers. This allows teams to enhance their current identity management with non-custodial wallet capabilities.
Key Benefits of Using Web3Auth
- User-Friendly Onboarding: Reduces barriers to entry with familiar login options.
- Flexible Integration: Works with both new and existing authentication systems.
- Enhanced Security: Provides non-custodial key management without sacrificing usability.
- Customizable Experience: Developers control which login methods and wallets are presented.
