On Windows 10, Windows Hello is a feature that allows you to use biometric authentication (such as your face or fingerprint) or a PIN to sign in to your account without the need to type complicated passwords.
Starting with the October 2018 Update (version 1809), Windows 10 introduces support for FIDO2 and CTAP2 security standards that allows to extend the same password-less experience to sign in to a Microsoft account online using Windows Hello or a security key. (As long as you use Microsoft Edge to access your account.)
In this guide, you’ll learn the steps to configure Windows Hello face, fingerprint, or PIN to sign in to your Microsoft account online without the use of password on Windows 10.
How to set up Windows Hello to access your Microsoft account
To set up Windows Hello to sign in to your Microsoft account online, use these steps:
-
Open Microsoft Edge.
-
Sign in to your account.
-
Click on the Security tab.
-
Click the more security options link.
-
Under “Windows Hello and security keys,” click the Set up Windows Hello link.
Quick Tip: If you don’t see the options as shown in the screenshot above, then you’re not running the version of Windows 10 that supports this feature, or you’re not using Microsoft Edge. -
Click the Next button.
-
Confirm your Microsoft account password. (In my case using a PIN password.)
-
Type a descriptive name for the sign-in method. (This will help to identify on which device you signed in using Windows Hello.)
-
Click the Next button.
-
Click the Got it button.
Once you’ve completed the steps, you can start signing in to your Microsoft account online using Windows Hello face, fingerprint, or PIN.
You’ll also get an email notification letting you know of the security change in your account.
