<authentication mode="Forms">
      <forms name="appcookie" defaultUrl="login.aspx"></forms>
    </authentication>
can any one help me out?

You can use Client Application Services, this goes well if your Chat Application Server componet is a Service. You can use WCF or plain ASP.NET Services.

Also you might want to check out PeerToPeer Networking

And there is a sample Per Channel Chat application build using this technology.

Membership and profile management , it is specific to asp.net handled through IIS but if you try to implement like this type of authentication and authorization u may be able by using web service.

You can use it with your own database, by using the aspnet_regsql.exe tool, and if you use asp.net web service for the server chat component, you get well rounded solution.

Keep it simple, create a small form with two text boxes and a "remember me" checkbox.  Hash the password.  Store the user name and hashed password in a setting so you can resend it when the user comes back.
