Twitter Authentication Failing on Mobile (Web3Auth)

Help - Plug n Play
1

We’re currently facing an issue with Twitter authentication using Web3Auth. It works perfectly on laptops/desktops via browsers, but on mobile devices (both Android and iPhones), the authentication fails—even though everything is properly whitelisted.

Has anyone else experienced this issue? Is this a known limitation/bug with Web3Auth on mobile, or could it be something in our implementation?

Any guidance would be appreciated. Thanks!

Thanks for sharing the details about your Twitter authentication issue on mobile with Web3Auth. Here’s a summary for the support team and a few suggestions to help troubleshoot:

Issue Summary

  • SDK/Platform: Web3Auth Plug n Play (PnP)
  • Authentication Provider: Twitter
  • Devices Affected: Mobile (Android & iOS)
  • Works On: Desktop/Laptop browsers
  • Issue: Twitter authentication fails on mobile devices, despite correct whitelisting.

To Help Diagnose Further

Could you please provide the following (if possible):

  1. Web3Auth Initialization & Login Code Snippet
    This will help us check if the loginConfig and redirect URIs are set up correctly for mobile flows.

  2. Error Message or Screenshot
    If there’s any error message shown during the failed login, a screenshot or the exact message would be helpful.

  3. SDK Version
    Which version of the Web3Auth SDK are you using? (This helps us check for known issues.)

  4. Are you using a Custom Verifier?

    • If yes, please provide the verifier name and Twitter login method details.
    • If using your own authentication, please share the JWKS endpoint and a sample idToken (JWT).

Possible Causes & Suggestions

  • Twitter OAuth on Mobile:
    Twitter’s OAuth flow can behave differently on mobile browsers or in-app browsers (like WebView). Sometimes, pop-up blockers or redirect URI mismatches cause issues. Make sure your redirect URIs are correctly whitelisted for both web and mobile.

  • Mobile Integration Checklist:
    Double-check the Web3Auth Mobile Integration Checklist to ensure all required steps for mobile are covered.

  • dApp Share & Custom Verifiers:
    If you’re using a custom verifier, confirm that the dApp share and related settings are correctly implemented as described in the PnP iOS and React Native docs.

  • Browser Context:
    On mobile, authentication often involves switching between apps (your app ↔ browser ↔ app). If the browser context is lost or cookies are cleared, the auth flow may break.

Next Steps

We’ll help you get this sorted as quickly as possible! If you have any screenshots or logs, please upload them—they can speed up the troubleshooting process.

Thank you for your patience!
