Bro, firstly I would say nice start with the application.

I would suggest a few quick things for this simple application.
- Make the password text box as "password" so that you can hide the password you are typing. And put a button "Show Password" at the side, on which if you click then only the password will be visible.
- Make this app portable so that users can carry it on their pen drives anywhere.

I agree to the fact that Google Chrome and Firefox have it as a built in feature but making apps for yourself is a good idea always. What if the PC you are using is not yours ? In such cases these kind of apps will definitely be useful.

Good effort mate. I am always there if you need some help with coding things I know you don't but cheers
