gabriel-cheng/vaultapass ? reverse-engineered prompt

Build me a secure vault app for storing usernames, passwords, and other account details in one place.

I want a simple Java web app that lets me create an account, log in, and then safely save, view, edit, search, and delete my saved credentials. Each entry should support things like site name, username, password, notes, and maybe a URL or category. Make it feel clean and easy to use, with sensible defaults and good validation.

Please keep the data protected properly, with passwords stored securely and the app set up for local development with Docker too. If anything important is missing or unclear, check current docs online and make reasonable choices. I’d also like the project to be organized so it’s easy to run, test, and extend later.
