# Problem in forms authentication

I am using [forms authentication](https://www.mindstick.com/forum/311/forms-authentication-and-authorization) in my [web site](https://www.mindstick.com/articles/12285/the-finest-web-site-design-trends-you-may-expect-in-2017) and I defined this in my config.

Therefore I have an ASPNETDB.MDF. So do I need to have a [database](https://www.mindstick.com/articles/12226/use-of-database-in-sencha-extjs-and-insert-record-from-user-form-using-ajax) called ASPNETDB.MDF in my web [host](https://yourviews.mindstick.com/view/85456/foreign-direct-investment-fdi-and-its-impacts-on-host-countries)?

If that is the case then how do I [connect](https://www.mindstick.com/articles/12810/how-to-connect-tablet-to-external-monitor-or-flat-screen-tv-using-computer-adapters) this so that my site uses this to verify [users](https://www.mindstick.com/news/2244/issue-preventing-users-from-accessing-facebook-s-social-networking-platforms-has-been-resolved)?
