Hi, Howard_35_78

Welcome to the MicroSoft Community.



Yes, you must first register your YubiKey with your Outlook.com account, irrespective of whether you are using a local or an administrator account on your computer. Here’s how you can set it up:

1. Enable Two-Step Verification:
   
   • Log into your Outlook.com account.
     
   • Go to ‘Security Settings’ and enable ‘Two-step Verification’.
     
2. Add YubiKey as a Security Key:
   
   • In the ‘Security Basics’ page, click on ‘More Security Options’.
     
   • Under the ‘Windows Hello and Security Keys’ section, click on ‘Set up a Security key’.
     
   • Follow the prompts to add your YubiKey as a security key.
     

After these steps, you can use your YubiKey to authenticate yourself when logging into your Outlook.com account from any computer. When you insert your YubiKey into a USB port and touch the button on the YubiKey, it generates a one-time password to authenticate your login. This means that you don’t have to remember a password, making your account more secure against phishing and other attacks.

The YubiKey 5C NFC works with both local and administrator accounts and can be used to secure a wide range of online services that support FIDO U2F or FIDO2 protocols, including Microsoft accounts. Remember, it’s always recommended to have a backup login method (like a secondary email, phone number, or another security key) in case you lose your YubiKey.



If there is anything not clear or I can't understand your problem, please do not hesitate to let me know.

Yubikey Two-Factor Authentication

Hi....I just purchased a " Yubikey " to use with the password manager
LastPass and it works very well as a two-factor authentication. I sign on to my PC with my Microsoft account and would like to use the Yubikey as a two-factor there also. I can't seem to find a procedure at Microsoft that explains
how to set this up correctly. The last thing I want to do is lock myself out of my PC.

I need to know ;

(1) The procedure to setup a Yubikey with a Microsoft account.

(2) Will the Yubikey work OK on any PC that I may sign onto with my Microsoft account. I have several PC's i often sign into .

Any help will be appreciated.

Thanks.....Larry
