Tags PK18 Guide


  • To provide information on using Duo two-factor authentication when away from campus
  • To provide information on the various authentication methods you can use when traveling or studying abroad



  • Duo Security Two-factor Authentication
  • Duo Mobile App
    • Android, iPhone, or Windows smartphone
    • Android or iOS tablet
  • Mobile Phone (cell phone other than a smartphone)
  • Desk Phone (landline)
  • YubiKey 4 Series Security Key
    • YubiKey hardware token
    • U2F hardware device
    • U2F authenticator
    • U2F security token


  • You can use Duo when traveling or studying abroad
    • Duo will work in airplane mode, in areas without a cellular signal, and in locations with no Wi-Fi signal, because the Duo Mobile app (installed on your smartphone or tablet) can generate Duo Passcodes even when no network connection is available
    • Duo, when used with a U2F hardware device, will work in areas with unreliable Internet access or coverage 
  • Before you travel, MUIT recommends that you decide which Duo device option(s) you will use when away from campus and enroll a secondary device, in case your primary device is unavailable
  • If you plan to travel outside the U.S., be sure to check with your mobile carrier regarding any fees you may incur for phone calls or texts received while abroad
    • If you're concerned about data usage, select an authentication method like Duo Push or Duo Passcode — both are available via the Duo Mobile app






  • Travel scenario: You left your phone at home or the hotel
    • Suggested authentication option: Request a passcode from IT Help
      • Required: After you've enrolled your primary device for use with Duo Security, MUIT recommends that you add a second device to your account. This will give you the ability to log in to your applications if the device you use regularly to authenticate is damaged, lost, or forgotten
      • Not required: Duo Mobile app, Internet connection, phone service
    • Follow these KB instructions to request a bypass code

Can you resolve this issue yourself?
Can the end-user resolve the issue using the instructions given?
Or does the end-user need to request assistance from Miami UIT, a client office, or a vendor?
Yes! This is self-service with a smile.
