DUO

No. Having a smartphone makes for an easier and more secure experience with Duo Push. However, if your organization permits it, it is also possible to enroll a non-smartphone mobile device or landline to receive SMS passcodes or phone calls.

Duo Push authentication requests require a minimal amount of data -- less than 2KB per authentication. For example, you would only consume 1 megabyte (MB) of data if you were to authenticate 500 times in a given month.

If you have access to the "Manage devices" or "My Settings & Devices" link (the self-service portal) at the Duo Prompt and are currently able to authenticate with a device, you may:
● Add additional devices
● Designate your "default" device that receives authentication requests in addition to your preferred authentication method (available in the Traditional Prompt)
● Reactivate Duo Mobile if you got a new phone but kept your number
● Change the name of your device (ex. "Personal Cell" or "Work Phone")
● Remove a device

There are several reasons this could be happening. Try the following to troubleshoot:
1. Make sure your enrolled device has a cellular network or WiFi connection.
2. Have the Duo Mobile app open when you authenticate.
3. If the above solutions don’t work, try using another authentication method, such as passcodes provided in the Duo Mobile app.
