Now that you have one DUO device registered for 2-factor authentication let’s get a second one setup so that if anything happens to the first device you’re not locked out of email or Teams!  Here are a few examples of good secondary devices to register.

• If you have an office phone you can register it’s number.
• A spouse/partner/friend’s phone number is also a good secondary device.
• RamTech has hardware tokens that can be purchased which generate passcodes to that can be typed in.

If you have any questions or if this is your first time hearing about DUO this guide will help you answer them (https://cnsit.colostate.edu/kb/duo-best-practice/), and if you need any further support you can submit a ticket using (https://cnsit.colostate.edu/help).
