Privy "User already authenticated" Bug Reproduction

Bug Summary

loginWithSiwe() throws "User already authenticated" error even after calling logout().

Package Version

• @privy-io/react-auth: ^3.13.0

Steps to Reproduce

1. Connect wallet A (MetaMask with multiple accounts)
2. Click "Login with SIWE" - signs and authenticates with wallet A
3. Switch to wallet B in MetaMask
4. App automatically detects the account change and:
   • Calls logout()
   • Attempts loginWithSiwe() with wallet B

Expected Behavior

• loginWithSiwe() should succeed with wallet B
• Linked embedded wallet should be available for wallet B

Actual Behavior

loginWithSiwe() throws: Error: User already authenticated

This happens even though:

• logout() was called and completed
• The wallet address has changed to wallet B
• We expect a fresh authentication flow

Additionally:

• Cannot get the linked embedded wallet with wallet B

Setup

1. Replace YOUR_PRIVY_APP_ID in src/main.tsx with your Privy App ID
2. Run:

   npm install
   npm run dev

Online Demo

To run on StackBlitz or CodeSandbox:

1. Go to https://stackblitz.com or https://codesandbox.io
2. Create a new "React (Vite)" project
3. Copy the files from this folder
4. Replace the Privy App ID
5. Run the project

Additional Notes

• The app automatically detects wallet account changes via useEffect watching the address
• When an account change is detected (after SIWE auth), the app:
  1. Calls logout() to clear Privy session
  2. Immediately attempts loginWithSiwe() with the new wallet
• The bug occurs: even after logout() completes, loginWithSiwe() throws "User already authenticated"
• The Privy authenticated state may show false after logout, but loginWithSiwe still fails
• The linked embedded wallet cannot be obtained for the new wallet (wallet B)
