Set up the YubiKey for Microsoft
Login to Microsoft
- On the user's computer, open Security info: https://mysignins.microsoft.com/security-info
- Sign in to the user's work/school account and complete the existing MFA challenge.
- Select Add sign-in method → Passkey → Next.



- When Microsoft asks where to save the passkey, select Security key. Note: You may need to select Use another device or More options first.

Insert the YubiKey into the USB port


- Follow the Windows/browser prompt to create or enter the YubiKey's PIN, then physically touch the YubiKey when prompted.


Microsoft will then let you name the Security Key for later.

Microsoft returns you to Security info. Give the new sign-in method a recognizable name and select Done.
Microsoft identifies a FIDO2 security key as a device-bound passkey where the private key remains on the physical security key.
