# What are the technical requirements to support passkeys?

## Technical Requirements to Support Passkeys

Implementing passkeys requires compliance with **FIDO2 and WebAuthn standards** to enable
secure, [passwordless authentication](https://www.corbado.com/glossary/passwordless-authentication). Below are
the **key technical prerequisites** for supporting passkeys in web and mobile
applications.

### 1. WebAuthn and FIDO2 Support

- Passkeys are built on **WebAuthn (Web Authentication API)** and require browsers,
  servers, and [authenticators](https://www.corbado.com/glossary/authenticator) that comply with the **FIDO2
  standard**.
- Ensure your authentication system can **generate, store, and validate public key
  credentials**.

### 2. Browser & OS Compatibility

- Major browsers **support WebAuthn**, including:
    - Google Chrome (desktop & mobile)
    - Microsoft Edge
    - Apple Safari (macOS & [iOS](https://www.corbado.com/blog/webauthn-errors))
    - Mozilla Firefox
- Operating systems must allow **biometric authentication (Face ID, Touch ID, Windows
  Hello) or hardware security keys** (e.g., [YubiKeys](https://www.corbado.com/glossary/yubikey)).

### 3. Backend Infrastructure

- **Passkey Registration & Storage:**
    - Store **public keys** securely in your database while the **private key remains on
      the user’s device**.
- **Authentication Flow:**
    - Implement WebAuthn authentication requests that verify user identity through the
      stored public key.
- **Relying Party Configuration:**
    - Set up a **Relying Party ID (RP ID)** that matches your website’s domain to prevent
      [phishing](https://www.corbado.com/glossary/phishing) attacks.

### 4. Authentication Devices & Credential Storage

- Devices should support **device-bound or synced passkeys**:
    - **Device-bound passkeys** (stored locally on
      [hardware security keys](https://www.corbado.com/blog/best-fido2-hardware-security-keys) or
      biometric-enabled devices).
    - **Synced passkeys** (cloud-synced across devices via Apple
      [iCloud Keychain](https://www.corbado.com/glossary/icloud-keychain),
      [Google Password Manager](https://www.corbado.com/blog/how-to-use-google-password-manager), etc.).

### 5. User Experience & UI Components

- Implement a **user-friendly passkey enrollment and authentication flow**.
- Provide clear instructions on **how users can register, use, and recover passkeys**.

## Final Verdict

To support passkeys, ensure your authentication system integrates WebAuthn, supports
[FIDO2](https://www.corbado.com/glossary/fido2)-compliant [authenticators](https://www.corbado.com/glossary/authenticator), and provides
a smooth user experience across devices and browsers. **Passkeys enhance security,
eliminate phishing risks, and offer seamless authentication—making them essential for
modern web and mobile applications.**
