Digital security is critical – and two-factor authentication is an effective way to increase the security of CU’s communications, documents and more. That’s why we’re bringing two-factor authentication to your Office 365 applications. This decreases the likelihood that others can access your data, even if they have your password.

Later this summer, you will need to log in to the Office 365 suite using your user password and a one-time code that can be sent to you via text message or phone call. Each two-factor login session will last up to two weeks on a given device and cover all Office applications except Teams. Users will have to log in to Teams separately using the same two-factor process.

If you have additional questions, reach out the UIS Service Desk at help@cu.edu or 303-860-HELP.
