# Passkey Funnel Analysis

> Visual representation of passkey / user authentication flows to identify bottlenecks and optimize passkey adoption paths.

**Passkey Funnel Analysis** provides process mining for authentication, showing exactly how users navigate through your passkey implementation to identify optimization opportunities.

## Overview

The funnel visualization shows:

* **User Flow Paths**: How users progress through authentication
* **Drop-off Points**: Where users abandon or fail
* **Success Rates**: Completion percentages at each step
* **Platform Comparisons**: Performance across web/app

## Key Performance Indicators

### Top-Level Metrics

* **Gradual Rollout Progress**: Percentage of users eligible for passkeys
* **Passkey Intelligence Filtering**: Users filtered by intelligence rules
* **Append Rates**: Most critical metric for passkey creation
* **Login Success**: Authentication completion rates

## Append (Creation) Analysis

### Primary Append Flow

Track passkey creation during login:

1. User completes conventional login
2. Gradual rollout allows passkey creation
3. Passkey Intelligence approves
4. Append screen shown
5. Passkey successfully created

### Additional Append Scenarios

* **Auto-Healing**: Append after authentication errors
* **Post-Hybrid**: Creation after cross-device authentication
* **Account Settings**: Manual creation from passkey list

<Tip>
  Monitor append rates across all scenarios - users who fail initial creation often succeed through alternative paths.
</Tip>

## Login Flow Analysis

### Authentication Paths

Visualize how users authenticate:

* **Passkey Offered**: Users eligible for passkey login
* **Method Selection**: Platform authenticator vs. cross-device
* **Completion Rates**: Success percentages for each path
* **Fallback Usage**: Automatic and manual fallback rates

### Critical Metrics

* **Usage Success**: Successful passkey authentications
* **Fallback Frequency**: How often fallbacks are used
* **Auto-Switch Rate**: System-initiated fallbacks

## Bottleneck Identification

### Abort Analysis

Focus on high abort rates:

* **Explicit Aborts**: Users actively canceling
* **Implicit Aborts**: System-initiated cancellations
* **Error Patterns**: Recurring failure points

### Investigation Workflow

1. Identify high abort/error nodes
2. Filter debugging section for specific outcomes
3. Analyze user processes
4. Implement fixes
5. Monitor improvement
