SUNY Cortland uses a two-factor authentication solution called Duo. Your first factor of authentication is your username and password. Your second factor is Duo. Duo prevents anyone but you from accessing your account, even if they know your password. After you enroll, you will be prompted for Duo authentication when you access myRedDragon or your SUNY Cortland email account.
Passwords are increasingly easy to compromise. They can often be stolen, guessed, or hacked – you might not even know someone is accessing your account. By adding Duo to your account, you are not only helping to protect your account but you are helping to protect your colleagues, the students, and the SUNY Cortland community.
Staff are currently being phased into Duo. Information Resources have been contacting departments and scheduling their moves to Duo since June 2018. All staff are expected to be moved by the end of 2020.
Faculty are currently being phased into Duo. Information Resources is working with academic chairs to schedule their department’s move to Duo.
All SUNY Cortland students have been enrolled in Duo as of Fall 2019. Freshman and transfer students will not be prompted to enroll in Duo until after Drop/Add week has concluded.
You have a choice of what authentication method you will use. You need at least one method. Whenever possible, we recommend setting up a backup method in case your primary Duo method is unavailable.
A USB token looks like a regular USB thumb drive. To authenticate with a USB token, you plug it into your computer and touch a small circular area on the token when prompted to do so.
Students should visit The Help Center in the Memorial Library to inquire about obtaining a token. If you are a student with a disability and require a USB token, contact Jeremy Zhe-Heimerman in the Disability Resources Office at 607-753-2358.
Faculty/Staff can place an order for a token through the Hardware/Software Request System in myRedDragon. If you have questions about how to order through the Hardware/Software Request System, please see our training and information page..
We currently only have tokens compatible with a USB port. This means your device needs to have a USB port. If you do not have a USB port but are still interested in using a token, contact the Technology Help Center to figure out what might be available to you.
USB tokens only work in Safari, Google Chrome, and Mozilla Firefox. If you are having trouble with your token, make sure your web browser is up to date.
If you have lost or misplaced your token, contact the Technology Help Center at 607-753-2500 to report it.
Sign into myRedDragon and navigate to the Tech Help tab. Look on the right hand side of the page for the Duo channel. Follow the instructions to setup your authentication method(s).
Freshman & Transfer Students: If you are a freshman or a transfer student, you will be prompted to enroll in Duo after drop/add week.
Alumni: After graduation, Duo will be removed from your account.
After retirement, Duo will be removed from your account.
Study Abroad Students
We will be working with you and the International Programs office to ensure your access to myRedDragon is uninterrupted during your travels. Keep an eye out for special instructions regarding Duo.
International Students will be required to enroll in Duo. When they depart from SUNY Cortland, Duo will be removed from their accounts.
If you are travelling outside of the United States and know you will need to sign into myRedDragon or check your SUNY Cortland email, we recommend contacting The Help Center to make the necessary preparations.
Your Duo Settings menu is not located inside of myRedDragon. You have to select it before you authenticate.
TIP: If you have checked “Remember me” and need to get to the Settings menu, sign into myRedDragon in a different web browser.
There are known compatibility problems with a few mobile mail apps and Duo. Below is a list of apps that are compatible as of August 2019.
Androids - Outlook
iPhone iOS 11.x or greater - Mail or Outlook
iPhone iOS 10.x or less - Webmail
After you have setup your authentication method, you should see a check box to “remember me”. When you check this box, it is by web browser (not by device or account). Faculty/Staff can select to “Remember Me” for 3 days. Students can select to “Remember Me” for 21 days.
TIP: You will need to use a back-up authentication method to add your new phone. If the Duo Mobile app is your only authentication method see instructions below.
Duo Mobile's restore functionality lets you back up your Duo settings for recovery to the same device or new device.
Setting up a backup of Duo is not required and is a decision we encourage individuals to make on their own. If you get a new phone/device, you will be able to reactivate Duo using a backup method or by using the Call me or Enter a Passcode options to authenticate.
For detailed instructions on how to backup and restore Duo visit Duo's Guide to Backup and Restore..
This may be happening because the Duo app is already open on your mobile phone. Quit out of the Duo app and test sending the push notification again. If you continue to have problems, uninstall and reinstall the Duo app from your mobile phone.
