Passkey Process & User Search provides powerful debugging capabilities for investigating authentication issues at the individual user level, essential for supporting users at scale.

​
Process Search (90% of Cases)

The primary debugging tool for investigating user-reported issues.

​
Search Capabilities

  • User Identification: Search by email address or user ID
  • Process Filtering: Filter by process type, time range, OS, and browser
  • Pro Mode: Advanced filtering options for detailed investigation

​
Process Details View

Each process provides comprehensive debugging information:

​
User Information (Top Left)

  • User ID
  • All passkeys and credentials (active/deleted)
  • Password managers detected

​
Technical Context (Top Right)

  • Platform and user agent details
  • Device capabilities (Bluetooth)
  • WebAuthn features: Conditional UI, hybrid support status

​
Event Timeline (Bottom)

Two lanes showing the authentication flow:
  • Sub-processes: High-level authentication steps
  • Events: Detailed technical data with 2-3 events per sub-process
The real debugging work happens in the event lane at the bottom. Look for errors, timeouts, and unexpected behaviors in the technical details.

​
Common Issues to look for

  • Timeout Errors: User didn’t complete authentication in time
  • Duplicate Passkey Attempts: User trying to create passkey on already-registered device
  • Client-Side Errors: Browser or device-specific failures
  • Password Manager Conflicts: Issues with third-party credential managers

​
User Search (10% of Cases)

For complex multi-device scenarios and cross-device authentication issues.
  • Investigating cross-device authentication problems
  • Understanding multi-device user journeys
  • Analyzing long-term user behavior patterns
  • Debugging edge cases not visible in single processes

​
User Search Features

​
Comprehensive User View

  • All processes concatenated over months/years
  • Complete device inventory and usage patterns
  • Cross-platform authentication history

​
Device Analysis

Track user activity across all devices:
  • Device Inventory: All devices user has accessed from
  • Passkey Distribution: Which devices have passkeys
  • Usage Patterns: Login and creation statistics per device
  • Browser Breakdown: Activity across different browsers
Multi-device scenarios are common sources of confusion. Use User Search to understand which devices have passkeys and where users are experiencing issues.

​
Key Insights from Debugging

​
Client-Side Visibility

Corbado provides unique client-side telemetry that was previously a black box:
  • Detailed passkey intelligence data
  • Device capability information
  • Password manager interactions
  • WebAuthn API responses

​
Proactive Issue Resolution

  • Once you identify an issue, search for other affected users
  • Check if specific OS versions or browsers are impacted
  • Implement fixes before more users encounter the problem
The debugging tools are particularly valuable for understanding edge cases with specific Android manufacturers or third-party password managers, which may only affect a small percentage of users but create significant friction.
