After March 31, 2026, older versions of the Duo Mobile Application (earlier than version 4.85) will no longer work for two-step login at UC Berkeley. To continue accessing campus systems that require CalNet two-step, you must update your Duo Mobile app or set up an alternative authentication method.
Your phone must meet these minimum requirements to support the latest version of Duo Mobile:
In UC’s ongoing commitment to safeguarding and protecting your data, UC Berkeley is introducing enhanced security methods for CalNet MFA verification (aka CalNet 2-Step).
After March 18, 2025, you will have two options:
The Campus Directory Update tool now offers privacy settings to let you choose what data is shared.
You now have the option to select how each particular data element is displayed in the directory. Options include:
Public: everyone can see this field; this is the default setting
Logged in: only those logged in via CalNet can see this field; or
Not visible: no one can see this field
After entering in your CalNet credentials, your browser will notify you that an authentication prompt has been sent to the registered device using your most recent method as the default. A side-by-side visual of this change is available below.
If you need to select a different method for authentication, click on “Other Options'' and a list of your registered devices will be displayed. To add or edit your registered devices, go to mycalnet.berkeley.edu.
If you use the Duo Mobile App to complete your CalNet 2-Step, you will start to see changes to the Duo Mobile user interface (UI) in October.
What to expect from this new version (v 4.0.0.).
For iOS changes will occur October 11 through 18, 2021.
For Android changes will occur October 11 through 15, 2021.

We asked Jeremy Rosenberg, Manager of the CalNet Identity and Access Management Team at UC Berkeley, why the CalNet 2-Step is such a big deal. Read on to find out!
What is 2-Step?
At Berkeley Law, the IT department has been at the forefront of adopting CalNet 2-Step, a two-step verification system using Duo, that better protects institutional and personal data. Gabriel Gonzalez, Chief Technical Officer at the law school, took a few moments to share his experiences with 2-Step.
Ever wonder what CalNet is up to?
CalNet maintains a Service Projects board with current and future projects sorted by priority and roughly laid out on a 1, 3 and 5 year timeline. This RoadMap enables the campus community to see what we are working on, to provide feedback, and help prioritize efforts. The board is public and can be viewed at:
For years, newly admitted students at Cal had to wait overnight to complete their onboarding tasks, such as creating their CalNet ID and passphrase. The delay was due to an overnight batch process in which new student data was migrated from Student Information Systems (SIS) to CalNet overnight, before a UID could be produced.
The UID is a Unique ID. Every campus user, whether student, staff, faculty, guest, or affiliate, has a UID. The presence of a UID allows a user to create a CalNet ID.
Students must wait no more.

We are working towards releasing new software early this spring to resume account expiration. We anticipate these changes to go into effect in mid-March 2017, but that date is subject to change.
The CalNet expiration process will be as follows:
