FIDO U2F and FIDO2 are supported on various versions of Windows operating systems, particularly those with integrated support for modern authentication methods. Below is a breakdown of which Windows versions support FIDO and FIDO2:

FIDO U2F (FIDO Universal 2nd Factor):

FIDO U2F can be supported on Windows systems that have compatible browsers (like Google Chrome, Firefox, or Edge), as these browsers handle the U2F authentication process.

• Windows 7: U2F is supported via web browsers like Chrome or Firefox, but it requires external software or drivers.
• Windows 8/8.1: U2F is supported through compatible browsers, similar to Windows 7.
• Windows 10: Full U2F support through compatible browsers like Chrome, Firefox, and Edge. It also benefits from broader system support for secure authentication.

FIDO2:

FIDO2 (which includes passwordless login and multi-factor authentication) has broader system-level support, especially in newer versions of Windows. Windows Hello, Microsoft's biometric authentication system, is built on the FIDO2 framework and is integrated into newer versions of Windows.

• Windows 10:
• Windows 11:

Summary:

• FIDO U2F: Supported on Windows 7 and later, mainly through web browsers.
• FIDO2: Fully supported on Windows 10 and Windows 11, integrated into Windows Hello for passwordless and multi-factor authentication.

For optimal FIDO2 support, Windows 10 and Windows 11 provide the best experience with full system and browser compatibility.

FIDO U2F and FIDO2 are supported on macOS through modern browsers such as Google Chrome, Mozilla Firefox, and Microsoft Edge. Additionally, FIDO2 is integrated with Touch ID on newer Mac devices for passwordless authentication.

Specific macOS Versions:

• macOS 10.12 Sierra and newer: Supports FIDO U2F through compatible browsers.
• macOS 10.14 Mojave and newer: Adds enhanced support for FIDO2 through both browsers and Touch ID.
• macOS 10.15 Catalina and newer: Fully supports FIDO2 authentication using Touch ID or external FIDO2 security keys.

Compatible Mac Devices:

• MacBook Air (2018 and later): Supports FIDO2 through Touch ID and FIDO U2F via browsers.
• MacBook Pro (2016 and later): Supports FIDO2 via Touch ID and browsers for FIDO U2F.
• iMac (2017 and later): Supports FIDO U2F and FIDO2 via external security keys or browsers.

Linux:

Linux distributions also support FIDO U2F and FIDO2 through tools like libfido2 and pam-u2f, as well as through compatible browsers. The support is mainly available in distributions using recent kernel versions.

Specific Linux Distributions and Versions:

• Ubuntu 18.04 LTS and newer: Supports FIDO U2F and FIDO2 through libfido2 and browsers like Chrome and Firefox.
• Fedora 30 and newer: Provides native support for FIDO U2F and FIDO2 through browser integration and system authentication tools.
• Debian 10 (Buster) and newer: Supports FIDO2 authentication through the installation of libpam-u2f and libfido2.
• Arch Linux: Always supports the latest versions of FIDO U2F and FIDO2 due to its rolling release model.

Supported Linux Brands and Models:

• Dell XPS Series: Works well with FIDO U2F and FIDO2 keys on distributions like Ubuntu and Fedora.
• System76 Laptops: Known for their native Linux support and compatibility with FIDO U2F and FIDO2 protocols.

To write a PIN code to your U2F or FIDO2 hardware device, the specific steps depend on the type of device you're using (such as a FIDO2 security key) and the protocol it supports. Generally, FIDO2 allows you to set a PIN code to enhance security, whereas U2F is primarily designed for basic two-factor authentication (2FA) and typically does not use a PIN code.

How to Set a PIN code for a FIDO2 Security Key:

Step 1: Prepare Your Device and Security Key

• Ensure you are using a hardware security key that supports the FIDO2 protocol.
• Insert your FIDO2 security key into your computer's USB-A or USB-C port, or connect via NFC if supported.

Step 2: Use Built-in OS Tools (Example: Windows)

1. Access Windows Settings:
2. Locate the Security Key:
3. Set or Change the PIN code:

Step 3: Complete the Setup

• Once the setup is complete, the PIN code will be stored on your FIDO2 security key. The next time you use it, you will be prompted to enter the PIN code to unlock the key during authentication.

How to Set a PIN code for a U2F Key:

• U2F protocol does not support PIN code setup. U2F is primarily used for basic two-factor authentication (2FA), and it does not include the passwordless login or PIN protection features available with FIDO2. Therefore, U2F keys do not use or support PIN codes.

Managing the Key Using Other Tools (For Different Devices):

Some security key manufacturers offer management tools that allow you to configure your FIDO2 key more flexibly.

• If you are using NOPKEY, you can download NOPKEY Manager, a software tool to set or change the PIN code for your FIDO2 key.

Summary:

1. FIDO2 security keys support PIN code setup via the operating system (like Windows or macOS) or via device management software.
2. U2F keys do not support PIN code functionality, as they are intended for basic two-factor authentication.

Setting a PIN code for your FIDO2 security key is an important step in adding an extra layer of protection in case the key is lost or stolen.

Microsoft Authenticator Passwordless Sign-in allows you to sign in to your Microsoft account without using a password, providing a more secure and convenient login experience. Instead of a traditional password, you authenticate using the Microsoft Authenticator app on your smartphone. Here’s how to set it up and use it:

Step 2: Add Your Microsoft Account to the App

1. Open the Microsoft Authenticator app.
2. Tap Add account.
3. Select Personal account or Work or School account, depending on the type of Microsoft account you're setting up.
4. Follow the on-screen instructions to sign in to your Microsoft account.

Step 3: Enable Passwordless Sign-In

1. Go to the Microsoft account security page by visiting account.microsoft.com.
2. Sign in with your Microsoft account credentials.
3. Go to Security > Advanced security options.
4. In the Passwordless account section, click Turn on.
5. You will be prompted to verify your identity using the Authenticator app.
6. Confirm the notification sent to your app by tapping Approve.

Step 4: Complete the Setup

1. After approving the notification, passwordless sign-in will be enabled for your Microsoft account.
2. You can now use the Authenticator app to sign in to your Microsoft account without needing a password.

How to Use Passwordless Sign-In

1. When signing in to a Microsoft service (e.g., Outlook, OneDrive, Xbox, etc.), enter your Microsoft account email.
2. Instead of entering your password, you will see a prompt asking you to approve the sign-in using the Microsoft Authenticator app.
3. Open the app, confirm your identity by approving the sign-in request, or use your fingerprint/Face ID to verify.
4. Once approved, you’ll be logged in without having to enter a password.

Benefits of Passwordless Sign-In with Microsoft Authenticator

• Increased Security: It reduces the risk of phishing, brute force attacks, and credential theft since no password is used.
• Convenience: No need to remember or enter long, complex passwords.
• Multi-factor Authentication (MFA): It works as a multi-factor authentication method since you need your phone and identity verification to log in.

Summary

Microsoft Authenticator Passwordless Sign-In is a fast, secure, and convenient way to access your Microsoft accounts without using traditional passwords. Simply set it up by enabling passwordless sign-in on your account, and use the Microsoft Authenticator app to approve login requests with ease.
