Fuel allows you to lock down use of your app with a security PIN. To enable this feature on your phone, please log into the app and tap the Settings gearbox button in the upper right-hand corner, and then select Enable PIN Lock. The following screen will prompt you to edit and confirm your 4-digit PIN. When PIN Lock is enabled, this 4-digit PIN will be required to access the app.
Make sure to remember your PIN!
Due to our aggressive security measures designed to keep your information safe, it is not possible to reclaim a security PIN within the Fuel app. If you do forget your PIN, you'll need to delete and re-install the app, at which point you will need to login with your Fuel account to use it again.
To remove the app:
iPhone: Hold down the app icon on your home screen until it begins to shake. Touch the small red x that appears and confirm deletion of the app and its data.
Android: Tap Menu > Settings > Applications > Manage Applications. Select the Fuel app, tap Uninstall, and confirm deletion.
To reinstall the app:
Search in the App Store or Google Play for Fuel, tap 'Install', and watch the magic happen. Launch the app, login as normal, and you're good to keep earning rewards at Fuel!
