A quick note on Duo Mobile and privacy

We understand that you may be hesitant to install Duo on your personal phone, but rest assured, Duo does not track your location, monitor your activity, or collect personal data. It simply adds an extra layer of security to protect your accounts, ensuring only you can access them.

  • Duo does NOT track your personal activity. It only checks basic details like the type of device you're using (e.g., iPhone, Windows PC) and whether it’s secure.
  • Duo does NOT collect your personal data. It does not track your location, what apps you use, or your browsing history.
  • Duo’s data collection is minimal and for security purposes only. It helps IT teams ensure devices are safe from cyber threats and does not spy on you.

If you’re concerned about privacy, rest assured that Duo is designed to protect your account without invading your personal space. Learn even more Duo Mobile Privacy Information.

Examples of high-risk scenarios include:
  • Accessing from a new device or IP address
  • Traveling to a new location
  • Unusual activity, such as multiple failed access attempts

Log in to your CalNet account using your usual credentials. This is your first-step verification.

You can use a passcode from the Duo App to complete the 2-Step on your smartphone from anywhere in the world–even if you do not have a WiFi or cellular connection! Note: Passcodes are single-use only; you must enter a new passcode each time you verify. Duo deactivates any old, unused passcodes once you request new ones. 

Step 1: View Passcode. On your phone, go to Duo Mobile. Tap the "CalNet - UC Berkeley" entry to view a passcode. 

Step 2: Log In to CalNet Log in to your CalNet account with your usual credentials. This is your first-step verification.

Passcodes can be generated from the Duo Mobile app or from the CalNet Account Manager. (See Requesting Passcodes for instructions on how to get one or more passcodes.)
