## Passkey Login Rate

Track login rates across your platforms:

* **Web Application**: Browser-based authentication rates
* **Native Apps**: iOS/Android app authentication rates
* **Absolute Numbers**: Total login volumes by platform
* **Trend Analysis**: Monitor changes over time

<Info>
  The passkey login rate is your primary success metric for evaluating passkey deployment effectiveness.
</Info>

## Initiation Methods

### Web Apps

Three ways users start passkey login on web:

* **Conditional UI**: Passkey autofill in username fields
* **One-Tap Button**: Username-less authentication for returning users
* **Text Field Login**: Traditional username entry followed by passkey prompt

### Native Apps

Mobile-specific initiation methods:

* **Passkey Overlay**: Primary method for native apps
* **Conditional UI**: Where supported
* **Manual Initiation**: User-triggered authentication

## Speed Comparison

Compare passkey vs. traditional authentication speed:

* **Average Speed**: Passkeys typically 4.3x faster
* **Percentile Analysis**:
  * 90th percentile (slowest 10%)
  * Median (50th percentile)
  * 25th percentile (fastest 25%)

<Tip>
  Use speed improvements as a key selling point when promoting passkey adoption to users and stakeholders.

## Operating System Breakdown

### Platform-Specific Analysis

Monitor performance by OS:

* **Login Rate by OS**: iOS, Android, Windows, macOS
* **Initiation Method Preferences**: How users authenticate on each platform
* **Trend Identification**: Spot platform-specific issues or improvements

### Investigation Triggers

Watch for:

* Login rates significantly lower on specific platforms
* Sudden drops in any OS category
* Diverging trends between platforms

<Warning>
  A stark decline in login rates for any OS requires immediate investigation - it may indicate compatibility issues or bugs.
