Two-Factor Authentication

Two-factor authentication (2FA), powered by Duo Security, is now available for all UConn populations. 2FA enhances data security by requiring two forms of identification to gain access to an online resource. On a system that requires 2FA, you first login with your NetID credentials and then verify your identity with a physical device linked to your NetID account. This additional layer of protection prevents anyone but you from accessing your accounts, even if they have obtained your username and password.

2FA is required for authentication into Core-CT. This requirement aligns with the State’s initiative and protects financial and personal information that can be vulnerable if an individual’s credentials are compromised.

Getting Started

You can set up 2FA by visiting the 2FA management portal page on or by logging in to any service protected by UConn SSO. Visit Two-Factor Authentication for more information.

Note: If you have any issues accessing your email after enabling 2FA, refer to the following Knowledge Base Article or contact the ITS Tech Support Center for assistance.

Managing the Service

You can make changes at any time to the devices linked to your account by visiting the 2FA management portal page. ITS recommends adding a backup device so that you have flexibility and additional options if you do not have your default 2FA device with you. You will be prompted to authenticate with your second factor before you can make changes.

If you misplace your 2FA device, contact the ITS Tech Support Center for assistance.

Tip: If you want the protection of 2FA but not the constant prompts to authenticate on your second factor, you can click the “Yes, this is my device” button after authenticating. As long as you are using the same browser and the same device, you will only receive one prompt every 30 days.
