Reown Authentication SIWX Usage

Reown Authentication is our flagship SIWX (Sign In With X) solution - the recommended way to handle user authentication for modern web3 applications. Built specifically for multi-chain environments, it abstracts away the complexity of validating wallets across EVM, Solana, and Bitcoin networks. With Reown Authentication you will be able to see and control the sessions of your users, get insights and much more. Read more about Reown Authentication features in the dedicated documentation.

​
Installation

​
Usage

import { createAppKit, ReownAuthentication } from '@reown/appkit-react-native'

const appkit = createAppKit({
  projectId,
  networks,
  metadata,
  // Add the following code line
  siwx: new ReownAuthentication()
})
Your app is now ready to use Reown Authentication within your SIWX configuration.

​
Extra configuration

ReownAuthentication works out of the box with no additional configuration required, but you can customize the experience with these parameters:

​
Available Parameters

new ReownAuthentication({
  localAuthStorageKey?: string    // Default: '@appkit/siwx-auth-token'
  localNonceStorageKey?: string   // Default: '@appkit/siwx-nonce-token'
  required?: boolean              // Default: true
  signOutOnDisconnect?: boolean   // Default: true
})

​
Examples

Custom storage keys: 
new ReownAuthentication({
  localAuthStorageKey: 'my-app-auth',
  localNonceStorageKey: 'my-app-nonce'
})
Optional authentication (users can skip signing and keep their wallet connected): 
new ReownAuthentication({
  required: false
})
signOutOnDisconnect: Controls whether the authentication session is automatically cleared when the wallet is disconnected. When set to true (default), users will need to re-authenticate after disconnecting their wallet. When set to false, the authentication session persists even after wallet disconnection. 
new ReownAuthentication({
  signOutOnDisconnect: false
})
