If you consider your information important and personal, then you probably don't want others to see or mess with your financial control. So enabling a Security Password may be the option to protect your data from other people!
When you enter the application with this feature enabled, a lock screen similar to the lock on your smartphone is displayed, requiring a security password that you create in the application or even your fingerprint, if available on the device.
To create a passcode:
Tap the three dots on the bottom bar (More Options menu) and tap the gear icon (Settings).
Now, choose a passcode and repeat it. Don't forget to save by tapping 'Save'.
To also register your fingerprint, set a password first. On the same screen, choose 'Lock with a fingerprint' option.
Done! Upon entering the application will be required the registered password or your digital.
