How Does 2Step Work?

Information Technology Services has partnered with Duo Security to bring 2Step Verification to CSUB.

With 2Step + Duo, you have many options to verify your identity. When you enter your username & password online, you have the option to verify your identity using a small hardware fob, an app on your smart phone or a call to your phone.
