# How to add a Passkey with different storage methods? Passkey is a secure and convenient authentication method that works across devices and platforms, offering flexible storage options. On **Apple system devices**, you can store a Passkey in **iCloud Keychain** by enabling iCloud and fingerprint recognition, or use Chrome with a Gmail account to save it in **Google Password Manager**. For local storage, opt for **Chrome on Mac** (device-specific only), or add it to other devices by scanning a QR code. For **Windows system devices**, store a Passkey in **Google Password Manager** via Chrome and a Gmail account with fingerprint verification, or choose **Windows Hello** for local storage. Each method seamlessly adapts to your device needs. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
