Duo Security: Two-Factor Authentication

Duo Security: Two-Factor Authentication

Case Western Reserve University (CWRU) has two-factor authentication available for active faculty, staff and students. Two-factor authentication protects users from unauthorized access to CWRU accounts, in the event that a password is compromised.

What is Two Factor Authentication?

Two-factor authentication provides added security by prompting you to enter a unique code at sign in, in addition to your password. The unique code, generated by your phone, is used only once. You can prompt the code from a device of your choosing (typically your smartphone). Using the Duo Mobile smart phone app (for iOS, Android) is the simplest and preferred method for obtaining the second factor codes, but tokens and other methods are available.

Theft of Credentials is Common

  • A user can be tricked into giving away their Network ID and passphrases through a malicious email or phishing or other online scams (View phishing examples here).
  • Many people reuse passwords or passphrases on other websites (Amazon; LinkedIn). If compromised, attackers often publish or sell the passphrases (https://www.infosecurity-magazine.com/news/linkedin-breach-weak-passwords/).
  • A user shares their Network ID and/or password (in violation of CWRU policy) with someone else.
  • A user logs in from an infected computer where attackers continue to run and record keystrokes of the users' passwords and/or passphrases (Keylogger).

What’s VPN Have to Do with This?

VPN is the first university service to require use of two-factor authentication, and in the summer of 2017 various online services that use the university's Single Sign On (SSO) service will use two-factor authentication.

All members of the university community are encouraged to enroll in Duo Security, CWRU's two-factor authentication service, today. Theft of Credentials is Common.
