How Do Emulators and Real Devices Compare in Passkey Testing?#

Both emulators and real devices play an important role in passkey testing, each offering distinct advantages and limitations. Here’s how they compare:

1. Advantages of Emulators#

• Cost-Effective: Emulators eliminate the need for physical devices, reducing hardware expenses.
• Broad Coverage: Easily simulate a wide range of devices, operating systems, and browsers.
• Efficiency: Ideal for repetitive testing tasks, such as verifying UI consistency across platforms.
• Controlled Environment: Enables precise testing under specific conditions, like network configurations or device settings.

2. Limitations of Emulators#

• Limited Realism: May not replicate real-world hardware and biometric interactions accurately.
• Performance Gaps: Lacks the ability to test device-specific behaviors, such as hardware acceleration or biometric input delays.
• Restricted Scenarios: Cannot simulate certain real-world conditions, such as device heat, battery levels, or physical inputs.

3. Advantages of Real Devices#

• Real-World Accuracy: Provides a true representation of user experiences, including hardware-specific quirks.
• Biometric Testing: Enables testing of fingerprint or facial recognition features used in passkey authentication.
• Cross-Device Scenarios: Validates the functionality of passkeys across actual hardware combinations.

4. Limitations of Real Devices#

• Higher Costs: Requires investment in maintaining a diverse set of devices for testing.
• Time-Consuming: Physical setup and maintenance can be slower compared to emulators.
• Limited Scalability: Testing on multiple real devices simultaneously is resource-intensive.

5. Best Practices#

• Combine Both Approaches: Use emulators for initial broad testing and real devices for final validation.
• Device Matrix Testing: Develop a testing matrix that includes both emulators and key real devices to ensure compatibility and accuracy.
• Cloud-Based Solutions: Leverage tools like BrowserStack or Sauce Labs to access real devices on demand.

By balancing the use of emulators and real devices, enterprises can ensure thorough and cost-effective passkey testing while maintaining high accuracy and reliability.

About Corbado

Corbado is the Passkey Intelligence Platform for CIAM teams running consumer authentication at scale. We help you see what IDP logs and generic analytics tools can't: which devices, OS versions, browsers and credential managers support passkeys, why enrollments don't turn into logins, where the WebAuthn flow fails and when an OS / browser update silently breaks login, all without replacing Okta, Auth0, Ping, Cognito or your in-house IDP. Two products: Corbado Observe layers observability for passkeys and any other login method. Corbado Connect adds managed passkeys with analytics built in (alongside your IDP). VicRoads runs passkeys for 5M+ users with Corbado (+80% passkey activation). Talk to a Passkey Expert →
