Depending on how you're setting this up, there are .NET controls that provide this functionality mostly for free (you don't have to write a lot of code to get it to work). Look into the Login control.
You need to decide whether you're authenticating against a domain or a database. Most likely it's a database. Just mask sure you hash the password in the database, and hash the password in the app, and compare the hashes.

I'm building a Web Application using ASP.NET MVC and I'd like to implement a Gamification system to make the user experience more exciting.
I'd like to start with a simple score for each user and as they progress and get more points they get badges and unlock new features for themselves, something similar to how Stackoverflow does it.
What appears challenging to me is how to check in the entire application, whether a user has reached a score that can recieve a badge. I don't want to duplicate my code and perform this check in every place that I'm incrementing a user's score.
I'd like to know how can I start implementing such a system. I know it's a broad question but I'm just looking for some starting ground and some good practice to begin.

Here is what is at the top of the view source page in IE... not good User Name and password showing...
Data Source=MySource;Initial Catalog=fdic;Persist Security
Info=True;User ID=username;Password=mypassword;User
Instance=False;Context Connection=False;Pooling=false;Connect
Timeout=4000; Exec usp_SYSTEM_CloseSaleSendEmail_db #id=14888 Invalid
object name 'dbo.vwWorkOrderAll'.
don't display it.... this is not displayed unless you write to it by either Response.Write or maybe setting a label/literal to the value of the connectionstring. ASP.NET or any other platform does not show connectionstring unless you show it yourself. seems like you have an exception not being caught and handled correctly either thus causing this output. you need to catch and handle the exception correctly.

If you can't see the picture, you can click this: http://sdrv.ms/ZQyhxK
You can use:
cmd.Parameters.AddWithValue("#userid",lbluserid.value)
You can also use:
SqlParameter[] p = new SqlParameter[1];
p[0] = new SqlParameter("#userid",lbluserid.value);
Then
cmd.Parameters.Add(p);

Can you please direct me to a tutorial or other resource for accomplishing the following:
Index page lists 50 states. Onlick of a state Y, the report page (report.aspx) will display info related to state Y, pulled from database.mdb, interspersed in HTML text.
I am not even sure what the terms and controls I need to be working with.
Thank you.

Do you know how to create the report? That is the first step. After that it is just a matter of passing the required parameter from one page to the next. Several methods can be used to do this: Response.Redirect/Request.QueryString, session variable, etc.

Let say that I have a website with some information that could be access externally. Those information need to be only change by the respected client. Example: Google Analytic or WordPress API key. How can I create a system that work like that (no matter the programming language)?
A number of smart people are working on a standard, and it's called OAuth. It already has a number of sample implementations, so it's pretty easy to get started.
Simple:
Generate a key for each user
Deny access for each request without this key
Currently, I use a concatenation of multiple MD5s with a salt. The MD5s are generated off of various concatenations of user data.
A good way of generating a key would be to store a GUID (Globally Unique Identifier) on each user record n the database. GUID is going to be unique and almost impossible to guess.
There are also infrastructure services that manage all this for you like http://www.3scale.net (disclosure I work there), http://www.mashery.com and http://www.apigee.com/.
