Integrations

Sign in with Ethereum (SIWE) can be integrated with various platforms and frameworks to provide seamless authentication experiences. This section covers popular integration options.

Available Integrations​

Discussion Platforms​

  • Discourse: Add SIWE authentication to your Discourse community forums

Authentication Libraries​

  • NextAuth.js: Integrate SIWE with NextAuth.js for Next.js applications
  • Auth0: Use SIWE with Auth0's enterprise authentication platform

Integration Benefits​

  • Decentralized Authentication: Users authenticate with their Ethereum wallets
  • No Passwords: Eliminates the need for traditional password-based authentication
  • ENS Support: Automatic username resolution from ENS names
  • Cross-Platform: Works across web, mobile, and desktop applications

Common Integration Patterns​

Frontend Integration​

Most integrations follow a similar pattern:

  1. Connect to user's wallet
  2. Create SIWE message
  3. Request signature from user
  4. Send signed message to backend for verification
  5. Establish authenticated session

Backend Verification​

Backend integrations typically:

  1. Receive signed SIWE message
  2. Verify signature cryptographically
  3. Validate message parameters (domain, nonce, expiration)
  4. Create user session or JWT token

Getting Started​

Choose the integration that best fits your technology stack:

  • For Next.js applications, start with NextAuth.js
  • For community platforms, see Discourse
  • For enterprise applications, explore Auth0
