The purpose of this guide is to guide you through the installation of Duo Security's mobile application that provides two-factor authentication to University systems. You will need the app to access those University services that require multi-factor authentication.
Multi-factor authentication with Duo Mobile is device-specific. If you change your phone for a new one, you can replace the old one from the Duo Mobile device management portal: https://jyu.login.duosecurity.com Note! You will need an old phone to accept the login to the management portal.
If you lose or break your phone, you will have to start the Duo Mobile installation from the beginning. In this case, the Duo MFA must first be reset. You can reset Duo Mobile multi-factor authentication yourself:
Resetting multi-factor authentication (after resetting, install Duo Mobile as described in section 1 of this guide)
In a computer web browser go to https://jyu.login.duosecurity.com
Step 1: Start screen: This window you will see, tell you that the deployment has been started. Click "Next".
Click on "Duo Mobile" to start the actual deployment:
Step 2: Entering a phone number
Under Country Code, select +358 from the drop-down menu and enter your phone number, taking into account the country code (the first digit is skipped, so if your number is 040 123 4567, enter 40 123 456 in the box). Then click on "Add phone Number ".
Check that you have entered the phone number correctly and click "Yes, it's correct". Otherwise, go back to the previous section and correct the phone number.
Step 3: Install Duo Mobile
The actual authentication is done with a mobile app on your mobile phone. On your phone, go to your operating system specific store (either the App Store or Google Play Store) and install the "Duo Mobile". Once you have installed the app, click the Next button.
Note! When downloading Duo Mobile to your smartphone or tablet, make sure your operating system version is new enough (Android 11 or newer, iOS 16.0 or newer) and that you have enough space (Android 30 MB and iOS 31.8 MB).
You can recognise the Duo mobile app by this icon:
Step 4: Activate Duo Mobile
Activate Duo Mobile by scanning the QR barcode (note: not the QR code in the help image) on the screen with the barcode reader in the DUO app. Open the Duo app from your phone and press "Use a QR code".
The application opens a camera that you need to point at the barcode displayed on your computer screen. Once the barcode is read, the application will move to the next screen, which will display the number you will use to verify your login.
Let's continue the installation for a while on the phone. If you wish, you can enter a name for the new account. By default, the name is JYU. Once you have named your account, press "Save".
Next, the Duo Mobile application suggests that you practice using Duo Mobile. You can choose to practice or skip it by selecting "Skip".
Allowing notifications will put the authentication request in the "notification menu" of your phone where it will be faster to accept it. It is recommended to select "Allow notifications".
Once the barcode has been read, press "Continue" in the browser (the button becomes active once the barcode has been read).
Step 5: complete
You can add alternative authentication methods if you wish. Otherwise, click "Skip for now" to proceed.
To complete the installation, click on "Log in with Duo". Your device is now ready to act as an authenticator when you log in.
Finally, click on "Send Me a Push" to test multi-factor authentication.
Then go to your phone and click "Allow" to accept the authentication.
Login
In the future, when you log in, the service will forward you to the Duo verification page.
In this case, go to the Duo app on your mobile phone to accept the sign-in. Once authentication is successful, the text "Success" will appear in green at the bottom and the service will sign you in.
