If your site has Two-step Verification enabled then you'll be required to enter a security code everytime you log into Kahootz.
In order to acquire a security code, you will first need to download and install an Authenticator App to your device.
On your device, open the app store eg: Play Store for Android, Windows Store for Microsoft devices or App Store for iOS users...
> Google (Android)
> Microsoft (Windows)
> Apple (iOS)
There's also an app called Twilio Authy which is compatible with Mobile, Desktop & Chrome...
> Twilio Authy (All Platforms)
Note: The below steps have been completed on an Android device...
Open "Play Store" and type "Authenticator" which will display a list of apps, I'll select "Microsoft Authenticator" and click install.
Once it's finished downloading/installing, open the app and click the 3 dots in the top-right corner, select "add account" from the drop-down menu.
Select other accounts (Google, Facebook , etc.) from the list which may ask for access to the camera, we recommend you select yes.
Then point the camera at the QR code during the Two-Step Verification wizard when logging in for the first time.
The account will now be added to the app which will display a unique 6 digit number that you'll need each time you log into Kahootz.
