Setup a Security Key
Sign in to the Azure Portal and update your authentication method settings here: https://mysignins.microsoft.com/security-info
Under Security info, click Add a method and choose Security key.
If MFA is already set up on your account, approve the sign-in request on your Microsoft Authenticator app to proceed.
Next select the key type you have, such as a USB device, and follow the prompts.
Create a PIN number for your device.
Touch your key to set it to your Azure account.
The setup is complete.
Next time you authenticate with a supported web browser, you will have the option to sign in with a security key instead of username and password.
