Multi Factor Authentication

Passwords alone are no longer enough of a barrier to protect accounts, information in them, or the transactions you can conduct with it.

Multi factor authentication, also known as two-factor authentication (2FA) is a challenge/response form of authentication that relies on at least 2 factors to validate you are the owner of the identity you are claiming.

We are all familiar with single factor authentication, the traditional username and password combination. MFA relies on something you know, like a password, and something you have or something you are. Something you have may be a phone or a code generating token associated with your account. Something you are may be a fingerprint, facial recognition scan, or iris scan; also known as biometrics.

The CSU is using Duo Security as the provider of the MFA services. More information on Duo

Anyone who would like to protect their personal information, communications, or ensure they are the only one who can use their account to conduct business with the University. Individuals with access to sensitive data of others will need to use MFA to log into systems or services hosting the data.

Do I have to do MFA for everything?

With the CSU's continued focus on securing level 1 data and ensuring the security of business transactions once enabled on your account you will need to use MFA at all services that currently support it.

Which services support MFA?

All services using the Stanislaus State Warrior Sign In page and Office 365 support the use of MFA to secure logins.

If I use the iOS or Android app can I use it for other services that support MFA?

Yes, there are other organizations and services that use MFA from the Duo Security or support the one-time PINs the app generates. You can use the app with those organizations or services if you would like. For support related to the Duo app 3rd party services you should reach out to the service provider.

What if I lose access to the device I setup for MFA?

We recommend you set up two devices capable of being used for MFA. A cellphone and a desk or home phone. This will allow you backup access to remove or add a new device in the event your primary device is lost, stolen, or inoperable.

If you have not set up a second device, please go to OIT Support in LX11 for assistance or call them at 209-667-3687.
