What to Expect Once is Installed to Your Workstation?

Duo is installed to all ‘Staff’ computers; sign in as usual with your network credentials. After submitting your credentials, you will be prompted by Duo with the window shown below. 

This window is where you will choose how you want Duo to contact you for your second factor approval. The recommended method is to Send a Push but first:

1. Check the box to remember me for 4 hours (this will prevent you from having to complete an MFA at every sign on and remain checked once checked)
2. Press ‘Send Push’ (this will send the push notification to the mobile device you registered for approval

A notification will be sent to your registered Duo device, on your mobile device you will press Approve and the computer will proceed with signing you in. 

Refer to the information below about approving push notifications from Android, Apple and Apple Watch devices.

What to expect when logging onto Experience or Office 365?

Logging into online resources such as Experience, Canvas or Office 365 is a bit different in that it presents a 3-digit challenge code for the user to confirm from their device. This helps prevent from MFA fatigue attacks, where attackers try to overwhelm a user with repeated push notifications until they approve a malicious login

(Android) DUO Push and Notifications

When the Duo Push notification shows up on your screen, tap where indicated to view the available actions: Approve or Deny.

---

Tap Approve in the notification to finish logging in to the Duo-protected application.

Tapping on the push request notification itself (instead of tapping the notification actions) takes you to the full Duo Push screen in Duo Mobile.

---

(Apple) DUO Push and Notifications

You can respond to Duo Push requests from the iOS lock screen or banner notification. The actions presented to you when you respond to the notification depend on your organization's Duo policy settings, such as whether or not you can approve the login request without PIN or biometric verification.

Perform a firm long press on the Duo Mobile notification from the lock screen to reveal the "Approve" or "Deny" actions. Tap an action and supply your passcode or biometric verification (face or fingerprint) to complete the action.

 

---

When your screen is unlocked, long-press or swipe down on the Duo Mobile banner notification received to reveal the authentication actions.

On devices that do not feature 3D Touch, swipe left on the Duo Mobile notification to reveal the actions.

Apple Watch Owners

Duo supports login request approval and passcode generation from an Apple Watch.

Apple Watch support requires Duo Mobile 3.8 or later. To see which version of Duo Mobile is installed on your device, go to the iOS Settings menu, then scroll down and tap Duo Mobile. The "System Info" section shows the app version.

You'll need to enable Apple Watch notifications for Duo Mobile. Open the Watch app on your phone, tap "My Watch", and scroll down then tap the entry for Duo. Enable "Show App on Apple Watch".

DUO Push

When you receive a push notification, you'll also see the notification on your paired Apple Watch if your phone is locked. Apple Watch’s Taptic Engine is a linear actuator inside the device that produces haptic feedback, meaning it literally taps you on the wrist whenever you receive an alert or notification. That means you’ll also feel a tap whenever a login request is sent via Duo Mobile, letting you quickly log in or deny the request.

You can approve the login or deny the login request without ever touching your phone.

You'll only see the Duo request on your watch when your phone is locked. Notifications won't go to your Apple Watch when your phone is unlocked.

---

Passcodes

You can also generate passcodes from the Duo Apple Watch. Simply launch the app from the watch and tap an account to generate a passcode for that account.

It's a good idea to take a few minutes to practice approving and denying Duo authentication requests if you haven't used Duo before. Tap Practice now to go through some training screens like this one. If you feel comfortable using Duo Mobile to log in to applications you can tap Skip.
