- Push notifications on a cell phone through the Duo app, also known as a "Duo Push" (Strongly Recommended, requires an Internet connection)
- If you have been issued a Clarkson owned cell phone, this is the mandatory methods

Please contact the Clarkson IT HelpDesk. They will immediately lock your Duo account and will provide you with an alternative method to authenticate. (You should also contact your mobile carrier and have them lock your mobile account as well)
What if I get a new phone?
You can use the self-service portal at https://duoportal.clarkson.edu/ to add a new mobile device. If your Duo account was previously locked due a lost phone incident, please contact the HelpDesk for assistance.
There is no cost to download or use the Duo Mobile smartphone app. Using the app to authenticate does not require an active data plan, texting plan or even a connection to the Internet. Clarkson will not reimburse you for using the Duo Mobile smartphone app on your personal device.
What if I don't have a cell phone or I don't want to install the Duo Mobile app on my personal smartphone?
The Duo Mobile app provides the most user-friendly experience; however, there is no requirement to use it on your personal smartphone. All users who have been issued a University-owned mobile device are required to use the Duo Mobile app on that device. Employees with personal smartphones who are unwilling to run the Duo Mobile app are eligible to receive an authentication token at no cost to their department. If the initial token is lost or damaged, departments will be charged a replacement cost of $30. To request a token, please contact the IT HelpDesk (email@example.com or 315-268-HELP).
