Authentication

[sonia.sardana]

There are diff ways to allow the user to login. Windows Authentication, Forms Authentication.

I want to ask that in depends on which situation,dat which method to use??

When I create a login form. I always login using

SqlConnection conn = new SqlConnection(ConfigurationManager.ConnectionStrings["ConnectionString"].ConnectionString);


WEB.CONFIG

<configuration>
<appSettings/>
<connectionStrings>
<add name="ConnectionString" connectionString="Data Source=(local);Initial catalog=sonia;User ID=sonia;Password=sonia;" providerName="System.Data.SqlClient"/>
</connectionStrings>
<system.web>


Above is which type of method???

Authentication has to do with a user logging into a website to access restricted functionality; such as administration module or what ever - whereas the code you're showing is your website/application making a connection/logging into the database.

It is two different things, and I think you're mixing up your concepts.
