Best Method When Deleting Apps Downloaded From Mac App Store?

Like you, i've downloaded an array of apps from the Mac App Store.

While I enjoy many apps, some I could go without.

As of late and for the past few years, I've always used the app "AppCleaner" to delete frivolous apps. Interestingly enough, whenever I drag an app I no longer need into AppCleaner, the apps and their related files and folders are deleted into the OSX trash together...

However, whenever I drag an app into this AppCleaner app, i'm always required to put in my OSX password...

I'm not saying this is a bad thing, simply that its been my way of ridding apps...and i'm simply wondering how others are going about deleting their apps that you've downloaded from the Mac App Store.
