Duo Push Authentication Guide - For UT San Antonio Faculty, Staff and Students

Duo Push makes authentication simple and reliable by using your mobile device to verify your login.

• Approve – Confirms your identity and grants access to the application.
• Deny – Blocks the login attempt, helping prevent unauthorized access.

Step 1: Initiate Authentication

• When logging into a Duo-protected application or service, select Duo Push as your authentication method.

• A login request will be sent to your registered mobile device.

 

Step 2: Respond to the Push Notification

• If the request is expected:
  Tap Approve to authenticate successfully
• If the request is unexpected:
  Tap Deny to reject the login attempt

Step 3: Handle Unexpected Requests

• After tapping Deny, you’ll be asked:
  “Was this a suspicious login?”

 

 

• Tap Yes if you did not initiate the login and suspect fraud.
  • Duo will:
    • Silence all Duo Mobile notifications for 20 minutes
    • Allow you to approve requests manually via the Duo Mobile app
    • Send a Fraudulent Authentication Report email to Duo Admins
  • Tap OK to continue to the Duo Mobile app.

 

• Tap No if the login was not suspicious (e.g., accidental request).

Step 4: Security Best Practices

• Denying a Duo Push has no negative implications.
• Marking a request as suspicious helps report fraudulent activity.
• Never respond to emails requesting your username, password, or phone number.
  • Forward suspicious emails to Spam@uthscsa.edu or click the Phish button.
  • Contact the Service Desk at 210-567-7777 opt 1 to verify legitimacy
