login link in master page

With few details, such as language, authentication proivders, etc... ill assume its the standard ASP.NET/C# stance :)

This could be achieved by checking if the user is authenicated and if they are, change the text and url of the control.

Using ASP.NET Users/Roles, this can be done by:

if(HttpContext.Current.User.Identity.IsAuthenticated)
{
// change text to 'logout' and update URL
}
else
{
// change text to 'login' and update URL
}
