3/18/2024 0 Comments Net google authenticator![]() ![]() A list of all of the available options for aspnet_regsql is available on the Microsoft website at ASP.NET SQL Server Registration Tool (Aspnet_regsql.exe). What we have just told aspnet_regsql to do is to connect to the server (specified with -S, in my case against my local SQL Server Express instance) using the login credentials specified, creating a database called ‘MvcTFA’ (-d MvcTFA) and installing all objects for ASP.NET Membership (-A all). The first one is using Windows Authentication to log into your SQL Server instance and the second is using the username and password that you have specified. \ SQLEXPRESS - U Satal - P Password1 - A all - d MvcTFA ![]() \ SQLEXPRESS - E - A all - d MvcTFA aspnet_regsql - S. If you want to install the ASP.NET Membership database through command line then you want to type in something along the lines of the following Īspnet_regsql - S. Open up command prompt and navigate to “C:\Windows\Microsoft.NET\Framework\v9”, if you want to use the wizard then just type in aspnet_regsql, which will open up the wizard. Personally I will be using the command line as that’s how I role *cheesy grin*. The first thing we need to do is install the SQL Server database that our two factor authentication application will be run against, there are two ways of doing this, the command line way or using the wizard. While I have a reasonable understanding of web security I am not an expert (I know enough to know that I don’t know enough), ASP.NET’s Membership library has had thousands of people reviewing the code and testing it’s implementations trying to find vulnerabilities, these then can be fixed, if I implement my own then it won’t get the same level of peer review unless it get’s really popular, which let’s be honest is unlikely. ![]() I’m lazy! No seriously, that’s a great reason not to write an authentication system, why do something when someone has already written it for you?.We will be using ASP.NET Membership for the username/password authentication part of the website, there are two reasons for this The projectįirst things first, let’s fire up Visual Studio and create a new ‘ASP.NET MVC 4 Web Application’, selecting the ‘Internet Application’ project template when prompted, I called mine MvcTFA, pretty much does what it says on the tin there. ![]() While I will be using ASP.NET MVC to demonstrate this you can do this with any framework you want, the principles will be the same. What this does is help to mitigate the chance that an attacker is intercepting your web traffic, which if you’re accessing a website that does not use HTTPS will mean that your username and password are plain text, while they may know your username and password without the thing you have they are unable to generate the one time password to go along with your login request to authenticate themselves. The second factor is commonly used for generating a one time password which will change over time, for example RSA keys change their code every minute and Google Authenticator changes the code every 30 seconds. Two factor authentication is where you use something that you know, a username and password, along with something that you have like an RSA key or a mobile. In this article I will demonstrate how to implement two factor authentication in your ASP.NET MVC application using Google Authentication. Google, GitHub, Hotmail and Dropbox just to name a few of the organisations that have embraced two factor authentication and provided it as an optional security measure. It’s becoming more and more common for websites to provide the capability of having two factor authentication as part of you login process. ![]()
