How can functional testing ensure a robust passkey system?

Functional testing is crucial for verifying that a passkey system operates as intended, ensuring a seamless and secure user experience. Here’s how functional testing contributes to robustness:

• Passkey Registration: Tests whether users can create passkeys successfully across different devices and platforms.
• Authentication: Ensures users can log in with passkeys without errors, including scenarios like cross-device usage.

• Cross-Platform Consistency: Tests the system on various operating systems (e.g., Windows, macOS, iOS, Android) and browsers.
• Device-Specific Checks: Identifies and resolves device-specific issues to maintain consistent functionality.

• Graceful Failures: Confirms that the system provides clear, user-friendly error messages for invalid inputs or failed authentication attempts.
• Fallback Mechanisms: Verifies that alternative authentication options (e.g., passwords, OTPs) are presented when needed.

• Intuitive Workflows: Ensures that registration and login processes are simple and straightforward.
• Feedback Mechanisms: Validates that users receive appropriate guidance during passkey setup and usage.

• Abnormal Scenarios: Tests less common scenarios, such as network interruptions or partially completed passkey ceremonies.
• Data Integrity: Ensures the system maintains accurate user credentials even during unexpected errors.

By addressing these areas, functional testing lays the groundwork for a robust passkey system that aligns with enterprise security and usability standards.
