Summary
Duo Two‑Factor Authentication (2FA) adds an extra layer of security to protect your UTHSC accounts. Even if someone steals your password, they cannot access your account without your second factor, such as a Duo push notification or passcode.
Prerequisites
- UT NetID
- A smartphone with the Duo Mobile app installed, or a hardware token
Instructions
What Is Two‑Factor Authentication (2FA)?
Two‑factor authentication requires you to verify your identity in two ways: your NetID password and a Duo approval request or passcode. This protects your account from unauthorized access, even if your password is compromised.
Duo Mobile
Duo Mobile is available for iPhone, Android, and wearables like Apple Watch.
- Download the app from your device’s app store.
- Follow the setup instructions provided during your first Duo login.
- If you do not have a smartphone, you may request a hardware token.
Important Security Reminder
- Never approve a Duo push you did not initiate.
- If you receive an unexpected Duo request, deny it immediately.
- Report suspicious activity to the Service Desk.
Troubleshooting
- If you receive Duo prompts you did not initiate, change your password immediately.
- If your phone is lost or replaced, contact the Service Desk to reactivate Duo.
- If you cannot use a smartphone, request a hardware token.
Additional Notes
- Duo protects access to key UTHSC applications and systems.
- Using 2FA is similar to the security used by online banking and other secure services.
