The default password for the user 'admin' is 'admin' on login screen?

My administrator user name and password is being displayed on login screen assisting user to login to the application.

message saying.. The default password for the user 'admin' is 'admin'. WHY?

I didn't want to let user know the admin credentials.

But, when I change administrator password then it disappeared.
There is 'if' logic on the standard login page that performs this.  It is intended to make your first application easier to login to until you get around to changing the password.  Just go into the Login screen and delete that code if you want.

Hope this helps,
