Duo Mobile app
Register your mobile device (smart phone or tablet) using the Duo Mobile app prior to traveling abroad. The app will allow you to generate a passcode on demand with or without an internet connection. If Internet access is available, Duo Push is an option that does not require the phone system, only internet.
Note: The Google Play Store cannot be accessed in China preventing those with Android devices from installing the Duo Mobile app in China. If traveling to China, you will need to already have Duo Mobile installed on your device or use one of the other options outlined below.
U2F device or YubiKey
A U2F device or YubiKey is a device that allows you to authenticate without needing a mobile device or phone in any geographical location. Simply plug the U2F device into the computer via USB/USB-C.
Note: U2F devices only work with Chrome browsers and do not work with Firefox.
Prior to going abroad, you can use the Two-Step Login page to text yourself a group of ten SMS passcodes to keep with you in case you do not have access to any of your devices.
The one-time codes are sent in groups of ten. To use them, click on the green “Enter a Passcode” button in the two-step login frame in your browser. Then click on “Text me new codes” in the blue bar. Each time you use the passcode method for two-step login, the first digit of the next code in the series will be shown in the blue bar.
Passcodes are valid for six months.
Temporary Bypass Code
You may request a temporary bypass code which can be used to registering a telephone device or land line upon arriving at the remote destination and determine what your foreign phone number is.
Request a temporary bypass code by contacting the Help Desk at email@example.com or (610) 330-5501.
