How should frontend applications be modified to support passkeys?

Supporting passkeys in a frontend application requires both UI updates and WebAuthn API integration to enable seamless user experiences. Here’s what to consider:

• Add clear buttons for passkey actions, such as:
  • "Continue with Passkey" for login.
  • "Create a Passkey" during onboarding.
  • "Manage Passkeys" in account settings.
• Use intuitive icons and text to explain the benefits of passkeys to users.

• Use the Web Authentication API to handle passkey creation and authentication flows.
  • For passkey creation: Call navigator.credentials.create().
  • For passkey authentication: Use navigator.credentials.get().
• Ensure the API calls are compatible across major browsers and devices.

• Design flows to handle device-specific prompts for passkey creation and authentication.
• Provide fallback options for devices or browsers that do not support passkeys.

• Implement robust error-handling logic to display helpful messages if a passkey creation or login attempt fails.
• Use generic error messages to avoid exposing account enumeration risks.

• Follow accessibility best practices for UI elements related to passkeys.
• Ensure passkey buttons and prompts are usable with screen readers and other assistive technologies.

• Test the passkey flows across various browsers and devices to ensure consistency.
• Use virtual authenticators during development for thorough testing of edge cases.

These updates ensure a smooth, secure, and user-friendly implementation of passkeys in your frontend application, driving higher adoption and satisfaction.
