2FA for FSU


What would happen if your password was stolen?

All it takes is one person to click a bad link and unknowingly share their credentials to create a domino effect of compromised accounts across campus. In the aftermath, accounts can be hacked, data can be wiped, paychecks can be rerouted … the list goes on.

With two-factor authentication (2FA) you can avoid these headaches knowing your FSU account is safe.

Why 2FA?

2FA is an extra layer of security designed to prevent unauthorized access to your FSU account. It protects your data from phishing attempts and other digital threats by determining that you are who you say you are, and not just someone using a stolen password.

How Does 2FA Work?

2FA requires you to verify your identity twice—once with your password and once with a device, typically a cellphone—before you can access protected information. After you sign in with your FSUID and password, you will be sent a request via mobile phone or another method to verify your identity. The process takes just a few clicks or taps.

2FA for FSU

FSU implemented 2-factor authentication (2FA) as an additional security measure on top of the traditional password to help combat cybersecurity threats. 2FA is designed to prevent unauthorized access to FSU accounts and protects sensitive information such as login credentials and personal information.

We require all students, faculty, staff, alumni and retirees to use 2FA to access the following university services:

  • University systems accessed via the FSU sign in page (CAS) 
  • FSU email accounts 
  • Office 365 applications 

2FA for FSU is powered by Duo. Duo offers a flexible set of authentication options including calling a cell phone, calling a landline, texting a passcode, sending a push notification to the Duo Mobile app or using a hardware token for those without access to a mobile device or internet.

If you would like to provide additional feedback on the 2FA process at FSU, please complete the FSU 2FA Feedback Survey.
