There is no option for a passcode, the only security option is a fingerprint. Also the budget feature is confusing. The budget is based on total income but not all outgoing categories are spending (for example savings, debt payments, or investments). So you don't have a spending total to work with. The lack of sign in or security passcode is a deal breaker for me anyway. I still use the desktop version on my laptop but as a mobile app it's not worth the bother. I uninstalled the app. Udate: despite what the developers keep telling me, when I go to security in the settings, there are two features that can be enabled. One is fingerprint and the other is screen lock. I am required to authenticate with my fingerprint in order to access these features. I can't even get that far because nothing happens when I touch the fingerprint sensor. I don't want to use my fingerprint for anything anyway. The main point is that there would appear to be no option for setting a passcode. Until someone gives me specific information on how I can make that happen, I will not be using the mobile app.
