As you decide which devices to use, consider what type of network signal you will have when you need to authenticate. For example, basement labs may not have strong WiFi signals or international travel may limit your access to cell or Wifi signals.
| Type of Network Signal | Best Devices to Use | Thoughts About Cost |
|---|
| Wifi and Cell service available | Smartphone, tablet, Cell Phone, Key fob or Internet based phone number. | Phone and text messages may incur fees, depending on your cell phone plan. |
| Wifi only | Smartphone, tablet, or internet-based phone number will work through the use of the DUO app.
Internet based phone number will also work on your computer or smartphone. | Data rates may apply. |
| Neither WiFi or Cell service is available | You can use the DUO app on your smart phone to access pass codes without any cell service.
You can also use the key fob to generate pass codes when you have no signal.
A land line can also be used. | Key Fob available for purchase here. |
