2FA, Authenticating without network access
I don’t have reliable cellular network access, or I am travelling and won't have an internet connection on my phone. How can I use 2FA?
There are several options for authenticating into your account when your smartphone does not have a network connection. The following options are perfect for travelling when you may not have internet access on all of your devices, or if you do not have access to your typical device.
1. Hardware tokens work without an internet connection. This means you can use them anywhere in the world to log into your account. More information can be found here: 2FA - Hardware tokens
2. The DUO Mobile app for smartphones allows you to generate a passcode to login, even if your phone is not connected to the internet. This is a free and easy way to authenticate wherever you are regardless of network connection. Instructions on using this method are below.
When prompted to authenticate while logging in to a 2FA-protected application, select Enter a Passcode.
Please note, there is also a "Remember Me" option, which will remember your login for 24 hours on the same device and browser. For more information, please visit: 2FA - Remember Me
Next, on your smartphone, open the Duo Mobile app.
Select the drop down arrow next to the University of Illinois profile, and you will be presented with a 6 digit code.
Enter this passcode in the authentication window, and select "Log In". You will then be brought to the application.
