A password in the code
Your homemade app is really handy, until you paste a real password into the code.
PASSWORDS
Don't expose secret keys
If a password, API key or bank code sits in the code, anyone who can see the app can take it. Keep them somewhere private.
DATA
Customer data needs an expert
If the app stores customers' phone numbers or takes payments, have someone who knows security review it before letting others use it.
BEST FIT
Best for your own tasks
Vibe coding works best for tools just for you, like a timesheet, a cost calculator, or a learning game for your kids.
