Duo Mobile app
Register your mobile device (smart phone or tablet) and install Duo Mobile prior to traveling abroad. You can generate a passcode using Duo Mobile without having an internet connection. If Internet access is available, Duo Push is an easy method of authenticating to two-step login.
Note: The Google Play Store cannot be accessed from China. Those with Android devices will need to already have Duo Mobile installed before arriving or to use one of the other authentication methods outlined below.
A YubiKey/U2F token allows you to authenticate to two-step login from anywhere without having internet access or using Duo Mobile. Simply plug the YubiKey/U2F token into the computer via USB/USB-C.
Before going abroad, you can text yourself a batch of ten passcodes for one-time use. Keep them with you in case you cannot access any of your devices. To use a passcode, 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 that can be used to register a mobile phone, landline, or other device after arriving at your destination.
Request a temporary bypass code by contacting the Help Desk at firstname.lastname@example.org or (610) 330-5501.
