MFA: Setting up Passkeys for Microsoft Authentication

Summary

This article explains several different ways to save Passkeys for logging into resources at USNH.  Passkeys are safer and more secure than passwords, and often easier to use as well! This article applies to all USNH account holders.

 

Types of Passkeys

A passkey lets you sign in without typing your password each time. It uses your device's built-in security, such as Face ID, fingerprint, screen lock, or device PIN. There are two primary types of passkeys – Synced Passkeys and Device-Bound Passkeys.

 

Synced Passkeys

The Apple Passwords app, Google Password Manager, and other password manager apps are examples of Synced Passkeys – the passkeys can exist in multiple places, wherever you can use that password manager.  

We recommend saving your passkey to: 

  • Apple Passwords (if you use iPhone/iPad/Mac) - iCloud sync must be enabled for passkeys to sync
  • Google Password Manager (if you use Android) - must be enabled for passkeys on your Android device

 

Device-Bound Passkeys

Hardware security keys (like YubiKey or Kensington), Windows Hello, and Microsoft Authenticator are examples of Device-Bound passkeys – they can only exist on the device they were generated on.

 

Limitations

  • Passkeys work only on your device. If you sign in on a public computer or your friend’s computer, you will not be able to use your passkey. Some platforms will allow you to sync your passkey among your devices. For example, an iPhone and a Mac signed into the same Apple Account can share a passkey.
  • Passkeys do not work on certain applications. These include commonly used applications such as LockDown Browser and Microsoft Remote Desktop.
  • Some browsers do not accept passkeys set up in other browsers. For example if you set up a passkey in Google Chrome, you might not be able to use it in Firefox, even if you are on the same device.

To avoid these issues, you should add another authentication method in addition to your passkey. You can use your passkey on devices and services that support it, but then use your other method in other situations.

 

How-To

Before you Begin

Make sure you have: 

Do not create a passkey on: 

Your USNH full username, like jbd2519@usnh.edu

A public computer

Your current password

A shared family computer

Your current MFA method

A classroom or lab computer

A personal phone or computer that only you use

A friend's phone

 

Task for Apple devices only: Enable Passkey Syncing on iOS or macOS**

**Windows users with an Android device can skip this task.

Confirm your iCloud keychain is enabled if you want your passwords to sync across Apple devices. You may sign in with your personal Apple ID on your USNH-managed device in order to sync your passwords and keychain to iCloud following the instructions below. 

  • If you do not have an Apple ID or you do not want to use your personal one on your institutional device, then you could create a new Apple ID  using your username@usnh.edu (like jbd2519@usnh.edu) for the email address, to be different from any personal Apple account that might already exist. Be sure to create a unique password for the new Apple account that is DIFFERENT from your USNH password.  You may NOT use your same USNH password for any non-USNH accounts.  See the USNH Password Policy.

Instructions for iPhone or iPad

Task: Create a new Passkey

You can register multiple passkeys for your USNH account.  Repeat this task as often as needed.

Instructions

Apple/Mac users - be sure to complete the task above first if you want to use synced passkeys across your iOS or macOS devices.

Step 1 - Open a web browser and visit https://myaccount.microsoft.com  

Step 2 - Expand My Account on the left

Step 3 - Select Security Info 

Step 4 - You may be prompted to sign in using MFA. If required, select or enter your username@usnh.edu (e.g. jbd2519@usnh.edu) and password. 

Step 5 - Once logged in, select Add sign-in method 

Step 6 - Select Passkey (not the "Passkey in Microsoft Authenticator" option)

Add sign-in passkey options.

 

Step 7 - Select Next and follow through the on-screen prompts. 

Step 8 -  Where you choose to save your passkey will affect whether it is a synced or device-bound passkey.

The options you see depend on many factors such as what device you are using when creating the passkey, which browser on that device, and whether or not you use a password manager. Read the screen carefully as it will tell you the details for the option you choose.

Some options you might see include:

  • This Windows device - to use Windows Hello on a personal computer, device-bound for that machine only.
  • Apple Passwords / iCloud Keychain - the default and most common option on macOS, synced if you have enabled iCloud sync as above.
  • iPhone, iPad, or Android device - save to a nearby mobile device via QR code and Bluetooth.  Requires Android 14 or higher, iOS 17 or higher.
  • Use a phone, tablet, or security key - use another device or a hardware security key such as YubiKey or Kensington.
  • Your browser profile - available in some browsers but not all. Passkeys stored in a browser profile are usually device-bound, stored locally within THAT browser on THAT device.
    • You must be in the same browser on the same device to use this passkey for signing into your USNH resources.
  • Google Password Manager - through your Chrome profile, as long as you are signed into a Google Chrome browser profile with your Google account. This will be a synced passkey, available wherever you are signed into Chrome with the same Google account. 
  • A password/passkey manager (e.g., 1Password, Bitwarden, KeePass, LastPass) - if a third-party password/passkey manager is installed or available in your browser, then that passkey is synced for use wherever that password/passkey manager is available to you.

Step 9 - When prompted, provide a clear Name for your new passkey, e.g. Jane's Google Pixel 11 or Joe's iPhone 17.  This is optional but recommended to help you distinguish it from other passkeys.

 

Outcome

You have registered and saved a new passkey. Where you choose to save your passkey will affect whether it is a synced or device-bound passkey as described above.
