RotaCloud supports two-step authentication (also known as two-factor authentication). This means that whenever you log into a new device, you'll be asked for a 6-digit code. This code is generated by an app on your smartphone.
To set up it, go to Settings -> Password & Security, and click 'Enable Two Factor Authentication'.
Next, download the Google Authenticator App, which will provide you with your 6-digit codes at the time of login.
Click the + icon in the top-right of the app, to add a new website.
Then, select 'Scan barcode' and use your phone's camera to scan the QR code displayed on the RotaCloud site.
After scanning, the Authenticator app will display a 6-digit code at all times for logging into RotaCloud. Enter this 6-digit code now, and click 'Validate'.
Now, you will be prompted for a code every time you log in - open the Authenticator app to see the current code and type/paste it in when requested.
