Passcodes and SMS Texts

Requesting Passcodes

If you need new passcodes, there are multiple ways you can request them.

Using the Duo Mobile Application

Using the CalNet Account Manager

Using "Text Me New Passcodes"

Using a Hardware Token

Get Passcode From Duo Mobile

On your phone, go to Duo Mobile. Tap the entry that says "CalNet - UC Berkeley" to generate a passcode. This works anywhere, even in places where you don't have a WiFi connection or can't get cell service.

Get Backup Passcodes from CalNet Account Manager

You can also request passcodes by logging in to the CalNet Account Manager and selecting Get Backup Passcodes at the bottom of the Device Control Panel screen.

Text Me New Codes

You can click Text me new codes at the bottom of the second-step verification login screen.

Then, check your cell phone for a text message with 10 passcodes. You can enter any of these codes for the second-step verification.


Get a Passcode from a Simple Hardware Token

Press the red power symbol on your simple hardware token. A numerical code will appear on the token’s screen.

Note: Passcodes are single-use only; you must enter a new passcode each time you verify.
