Use another field for authentication.

Generate some random string in that.Execute query when that field matches and makes that field empty after execution..
so whenever u want to run query u will need an correct match code

You shouldn't be storing the username in the get array. Use a session.

Btw, making your post red doesn't net you more responses.
