As a Roblox developer, it is currently too hard to safeguard your funds in the event of an account compromise (or otherwise). If you get cookie logged or sim swapped, or intoxicated, or you leave your devices unattended, someone could easily siphon your 
robux out of your account by making a few big purchases. That someone could be you 
MINOR NOTE
For <13 accounts (and <18 accounts in 
South Korea) there is a Parental Controls feature called Monthly Spend Restrictions. It makes it so you can’t spend over a certain amount of robux per month. This would be perfect. Please let me force myself to enter my “Account PIN” for every purchase over X robux within a day or month or week. Banks tend to have something like that too by the way.
Anyway,
If Roblox is able to address this issue, it would improve my development experience because I wouldn’t have to worry about this. It’s worrying. I’m worried. I’m not worried about the funds in my bank account because I know only a very small amount of it could be spent at a time. For my robux I can have no such peace of mind. Thank you.
