Windows 10: How to Delete Fido2 Platform Authenticators?

paul brady1 · Sep 7, 2022

HelloI am working with Fido2 Authenticators on my Win11 system that has a TPM. I have enrolled many test users with a Fido2 Platform Authenticator. The problem is how to delete these off the client without a re-install of windows?

Windows Hello & FIDO2 Security Keys authentication for shared devices

Are you tired of entering usernames and passwords? Windows Hello and FIDO2 Security keys allow you to carry your identity with you.

We have been on a journey to eliminate passwords. Today, we are delighted to announce an important milestone.

Microsoft has been aligned with the Fast Identity Online (FIDO) working group from the start, the alliance represents 250 organizations from various industries on a joint mission to replace passwords with an easy to use strong credential. With the recent ratification of FIDO2 security keys by the FIDO working group, we’re updating Windows Hello to enable secure authentication for many new scenarios.

FIDO2 Security Key

Imagine a helpdesk scenario where an employee can walk up to any device and simply log in using Windows Hello and not username and password. Another scenario is hospital medical staff that need access a patient records on a device no matter where the patient is located. Or a public-sector organization that wants secure authentication on devices while adhering to security policies and directives where the users credential needs to be physically separate from the device itself.

Microsoft and its partners have been working together on FIDO2 security keys for Windows Hello to enable easy and secure authentication on shared devices. Security keys allow you to carry your credential with you and safely authenticate to an Azure AD joined Windows 10 PC that’s part of your organization. A user can walk up to any device belonging to the organization and authenticate in a secure way – no need to enter a username and password or set-up Windows Hello beforehand. Unlike traditional passwords, these keys rely on high-security, public-key cryptography to provide strong authentication. These keys have all the benefits of a Trusted Platform Module (TPM) while also being portable enabling the increasing number of mobile workers.

FIDO2 compliant security keys provide secure authentication, independent of the form factor. The security key holds your credential and can be protected with an additional second factor like fingerprint (integrated into the security key) or a PIN to be entered at the Windows sign-in.

Our partners are working on a variety of security key form factors. Some examples include USB security keys and NFC enabled smartcards, just to name a few. We are looking forward to seeing new form factors and possibly applications on your phone that comply with the FIDO2 specification.

Passwordless FIDO2 verification on Android for Google Accounts

Passwords, combined with Google's automated protections, help secure billions of users around the world. But, new security technologies are surpassing passwords in terms of both strength and convenience. With this in mind, we are happy to announce that you can verify your identity by using your fingerprint or screen lock instead of a password when visiting certain Google services. The feature is available today on Pixel devices and coming to all Android 7+ devices over the next few days.

Simpler authentication experience when viewing your saved password for a website on passwords.google.com

These enhancements are built using the FIDO2 standards, W3C WebAuthn and FIDO CTAP, and are designed to provide simpler and more secure authentication experiences. They are a result of years of collaboration between Google and many other organizations in the FIDO Alliance and the W3C.

An important benefit of using FIDO2 versus interacting with the native fingerprint APIs on Android is that these biometric capabilities are now, for the first time, available on the web, allowing the same credentials be used by both native apps and web services. This means that a user only has to register their fingerprint with a service once and then the fingerprint will work for both the native application and the web service.

Note that your fingerprint is never sent to Google’s servers - it is securely stored on your device, and only a cryptographic proof that you’ve correctly scanned it is sent to Google’s servers. This is a fundamental part of the FIDO2 design.

Here is how it works

Google is using the FIDO2 capability on Android to register a platform-bound FIDO credential. We remember the credential for that specific Android device. Now, when the user visits a compatible service, such as passwords.google.com, we issue a WebAuthn “Get” call, passing in the credentialId that we got when creating the credential. The result is a valid FIDO2 signature.

High-level architecture of using fingerprint or screen lock on Android devices to verify a user’s identity without a password

Please follow the instructions below if you’d like to try it out.

Prerequisites

Phone is running Android 7.0 (Nougat) or later

Your personal Google Account is added to your Android device

Valid screen lock is set up on your Android device

To try it

Open the Chrome app on your Android device

Navigate to https://passwords.google.com

Choose a site to view or manage a saved password

Follow the instructions to confirm that it’s you trying signing in

You can find more detailed instructions here.

For additional security

Remember, Google's automated defenses securely block the overwhelming majority of sign-in attempts even if an attacker has your username or password. Further, you can protect your accounts with two-step verification (2SV), including Titan Security Keys and Android phone’s built-in security key.

Both security keys and local user verification based on biometrics use the FIDO2 standards. However, these two protections address different use cases. Security keys are used for bootstrapping a new device as a second factor as part of 2SV in order to make sure it’s the right owner of the account accessing it. Local user verification based on biometrics comes after bootstrapping a device and can be used for re-authentication during step-up flows to verify the identity of the already signed-in user.

What’s next

This new capability marks another step on our journey to making authentication safer and easier for everyone to use. As we continue to embrace the FIDO2 standard, you will start seeing more places where local alternatives to passwords are accepted as an authentication mechanism for Google and Google Cloud services. Check out to get an early glimpse of the use cases that we are working to enable next.
