To create a membership user

1. From the Website menu, click ASP.NET Configuration.

2. Select the Security tab, click the link to use the Security Setup Wizard, and then click Next.

3. Proceed to Step 2 of the wizard and select the From the Internet option.

The wizard displays a page where you can select the authentication method that your Web site will use.

This option specifies that your application will use Forms authentication, where users will log into the application using a login page that you will create later in this walkthrough.

4. Click Next.

The wizard displays the current default provider (data access component) that will be used to store membership information. For this walkthrough, it is sufficient to use the default provider, which stores membership information in a data file in the Application_Data folder of your Web site.

Note: 
In production applications that will support a substantial number of users, it is preferable to store membership information in a SQL Server using the AspNetSqlProvider. For more information, see Web Site Administration Tool Provider Tab and Installing the SQL Server Provider Database.

5. Click Next.

The wizard displays an option to create roles. You will perform this step separately later in the walkthrough. Therefore, do not select the Enable roles for this web site check box.

6. Click Next.

The wizard displays a page where you can create new users.

7. Enter information that defines a user of your application. Use the following values as guidelines. You can use any values that you like, but be sure to note your entries for later in the walkthrough.

User Name   Your name (with no spaces), or a sample name.

Password   A password. A strong password is recommended (one that includes uppercase and lowercase letters, punctuation, and that is at least eight characters long).

E-mail   Your personal e-mail address. Later in the walkthrough you will send yourself an e-mail message, so you need a legitimate e-mail address.

Security Question and Security Answer   Type a question and answer that can be used later if you need to recover your password.

Click Create User.

The wizard displays a confirmation page.
