Option to protect application

Day before yesterday I was working on my client account in which I had published my application. Since it had some mistake i decided to delete it and accidentally I deleted the original app I had in my account.

Before deleting I was prompted to confirm but I didnt realise that I am in my own account

There should be an option to password protect the application where in application can be deleted only after the admin enters a password for that particular app.

I think this is an important issue and needs attention
