## 1. Testing on Simulator

For passkey testing, you need to enable Touch ID (on older versions) or Face ID. Use the iOS Simulator menu:

**Features → Face ID / Touch ID → Enrolled**

To simulate Face ID / Touch ID:

**Features → Face ID / Touch ID → Matching Face / Matching Touch**

<Note>
  Simulate Face ID: `Command + Shift + M` / Simulate Touch ID: `Command + Shift + H`
</Note>
