Set up a security key as your verification method (2024)

You can use security keys as a passwordless sign-in method within your organization. A security key is a physical device that's used with a unique PIN to sign in to your work or school account. Because security keys require you to have the physical device and something that only you know, it's considered a stronger verification method than a username and password.

Using a security key as a passwordless authentication method is currently in public preview. If what you're seeing on your screen doesn't match what's being covered in this article, it means that your administrator hasn't turned on this feature yet. Until this feature is turned on, you must choose another authentication method from theSecurity Infopage. For more information about previews, seeSupplemental Terms of Use for Microsoft Azure Previews.

Notes:

  • If you don't see the security key option, it's possible that your organization doesn't allow you to use this option for verification. In this case, you'll need to choose another method or contact your organization's help desk for more assistance.

  • Before you can register a security key, you must have at least one additional security verification method registered.

What is a security key?

We currently support several designs and providers of security keys using theFast Identity Online(FIDO2) passwordless authentication protocols. These keys allow you to sign in to your work or school account to access your organization's cloud-based resources when on a supported device and web browser.

Your administrator or your organization will provide you with a security key if they require it for your work or school account. There are different types of security keys you can use, for example a USB key that you plug in to your device or an NFC key that you tap on an NFC reader. You can find out more information about your security key, including what type it is, from the manufacturer's documentation.

Note:If you're unable to use a FIDO2 security key, there are other passwordless verification methods you can use such as the Microsoft Authenticator app or Windows Hello. For more information about Windows Hello, seeWindows Hello overview.

Before you begin

Before you can register your security key, the following conditionsmust all be met:

  • Your administrator has turned on this feature for use within your organization.

  • You're on a device running the Windows 10 May 2019 Update and using a supported browser.

  • You have a physical security key approved by your administrator or your organization. Your security key must be both FIDO2 and Microsoft-compliant. If you have any questions about your security key and whether it's compatible, contact your organization's help desk.
