# Why are WebViews in mobile apps a challenge for passkeys?

## Why are WebViews in mobile apps a challenge for passkeys?

[WebViews](https://www.corbado.com/blog/native-app-passkeys), often used in mobile apps to render web content,
present unique challenges when implementing passkeys. These challenges stem from limited
support for WebAuthn features within many [WebView](https://www.corbado.com/blog/native-app-passkeys)
environments.

## Key Challenges with WebViews for Passkeys

### 1. Limited WebAuthn Support

- Many [WebViews](https://www.corbado.com/blog/native-app-passkeys) lack full support for WebAuthn APIs, making
  it difficult to enable passkey functionality.
- Native browsers like Chrome or Safari are typically more passkey-ready than
  [WebViews](https://www.corbado.com/blog/native-app-passkeys). Alternatively, a native implementation of
  passkeys in the [iOS](https://www.corbado.com/blog/webauthn-errors) or
  [Android](https://www.corbado.com/blog/how-to-enable-passkeys-android) app is possible.

### 2. Inconsistent Implementations

[WebView](https://www.corbado.com/blog/native-app-passkeys) capabilities vary by platform and version:

- **WKWebView** on [iOS](https://www.corbado.com/blog/webauthn-errors) offers better support but may still lack
  key WebAuthn features.
- [Android](https://www.corbado.com/blog/how-to-enable-passkeys-android) [WebView](https://www.corbado.com/blog/native-app-passkeys)
  implementations are often less consistent and may require custom configurations.

### 3. Security Constraints

- WebViews often have restricted environments that limit access to the local
  [authenticator](https://www.corbado.com/glossary/authenticator), such as [Face ID](https://www.corbado.com/faq/is-face-id-passkey),
  Touch ID or the [Android](https://www.corbado.com/blog/how-to-enable-passkeys-android) biometric equivalent.
- This can prevent seamless [passkey creation](https://www.corbado.com/blog/passkey-creation-best-practices) or
  usage within the app.

### 4. User Experience Issues

If passkeys don’t work within WebViews, users may need to switch to an external browser or
app for authentication, disrupting the login flow. Usually, the best passkey UX can be
achieved when using the native implementation of passkeys in the respective
[iOS](https://www.corbado.com/blog/webauthn-errors) or Android app development framework (e.g. Kotlin, Swift)

## Strategies to Address WebView Challenges

1. **Test WebView Compatibility:**
    - Use data from [State of Passkeys](https://state-of-passkeys.io) to identify WebView
      limitations.
    - Evaluate the specific WebView types (e.g., [WKWebView](https://www.corbado.com/blog/native-app-passkeys)
      vs. Android WebView) used in your app.

2. **Fallback Options:**
    - Redirect users to native browsers for authentication if WebView support is
      insufficient.
    - Maintain alternate MFA methods during the transition phase.

3. **Encourage Native Implementation:** Where possible, use
   [native app](https://www.corbado.com/blog/native-app-passkeys) components for passkey functionality instead of
   relying on WebViews.

4. **Work with Vendors:** Collaborate with WebView and platform providers to advocate for
   better WebAuthn support in future updates.

## Conclusion

WebViews pose significant challenges for passkeys due to limited WebAuthn support and
security constraints. By understanding these limitations and implementing strategies like
fallback options and [native app](https://www.corbado.com/blog/native-app-passkeys) components, you can ensure a
smoother passkey rollout.
