2. If prompted for authentication, sign in using your eRaider account.
   
   
3. Follow the steps in the Microsoft support article linked below, depending on which option you want to add:

• Synced passkey [best option for most users]
  • Still available to you even if you lose or replace your mobile device!
  • Store in any of the following: 
    • Apple Passwords (iCloud Keychain)
    • Google Password Manager
    • Microsoft Password Manager
    • Your favorite password manager (for example, LastPass, 1Password, etc.)
  • Available for signing in using any computer or mobile device supported by the password manager
• Device-bound passkey
  • Store in any of the following:
    • Security key (for example, YubiKey)
    • Microsoft Authenticator mobile app

IMPORTANT: Device-bound passkey options, such as Microsoft Authenticator, do not sync across your devices. If you get a new mobile phone, for instance, you will not be able to use the new phone to sign in to TTU services unless you take steps to set up the passkey on the new phone before getting rid of your previous phone. For this reason, synced passkeys stored in a password manager may be a better option for most users.

NOTE: At TTU, passkeys are not supported with Windows Hello at this time.
