Security :: Query Database For UserName And Password?
Feb 16, 2010
so I will admit this is a pretty stupid question. To my defense, I have never done it before. So take pity. I followed Joe Stagner's video on using the built-in authentication. Now, I would like to query a database using VB.net codebehind to verify if the user exists. I am clueless. Yes, I have a connection string already.
I got a username and password field which made by myself and a User database which is all manually made
So now I wish to know how to authenticate user using the username and password data enter by the user and match with the database data to verify user is a member and login?
For what i know, the code should be something like this
SELECT UserName, Password FROM dbo.User WHERE UserName - @UserName
@UserName = ?
How do i assign the value from my username text field to @UserName?
How do I use the FormsAuthentication.Authenticate(Username,Password) method to match against the generated Database?..since as far as I have read, it matches the values against the Web.config.
I have created a test user/password on my web site. The intent is to have prospective clients login and try out the tool. Instead of telling them the userid/password of the test user, I'd like to tweak the Login wizard.
In the Load event, I was able to specify login1.UserName = "test user"
But when I try to specify the password, I'm told it is a readonly field. How can I 'force' a specific password? Or, how can I call the login event directly and pass the needed values?
For testing I used this:[URL]Encrypts only the password is not encrypted and username.Why not?For security reasons, I would like also to encrypts username.
I have an intranet run with IIS, with basic authentication config. See more in this screenshot:
[URL]
Of course, then, when user login, this screen will appear:
[URL]
After successfully login, is there any method to get UserName (very easy to get) and also Password (don't know yet) from asp.net coding (run at server)
I am trying to implement a small site which requires users to login using Forms based authentication. I have followed the tutorials found on various sites on the net and in particular the one at [URL] This enabled me to get a sample environment in place but it seems as though I am having a problem authenticating a user for which I know the username and password are correct.
I have a ASP.Net 3.5 site with my login.aspx form in a folder named login, my default.aspx in the root of the site and my protected content in a folder called main.
I am authenticating against a SQL Server Express database, so I have ran the aspnet_regsql.exe command to populate my database.
I have added the following authentication/authorization lines to my web.config
I believe that my connection string and my database are ok because if i use the ASP.NET Configuration from within Visual Studio I can create and manage my users and I can also see them in the tables in the SQL Server. Also if I do enter any incorect credentials in my login page the page tells me that the password is incorrect.
I am trying to login usng form authentication from my web.config but it does not work. In the web.config i have the following: (i am going to make the password secure but just need to work with the basics
I had created an application which authenticate the user from the Active Directory,I had published the code on the server but when the page executes it ask for the username/password.i don't want this to happen, how to suppress this username/password screen.
I am writing a simple plugin for IE. I need to store a password and username setting for the user who uses the plugin. I know that I can store the username/password in the registry, I can manually encrypt it using the encription classes with .NET, or I can store it in a config file and encrypt the config file. I was wondering if there is a specific pattern/mechanism that I should use to store password and username.
I have a website that uses master page. I want a pop up to display so that user has to enter valid user name/psw in order to see pages. There will be only one username/password so web.config will store that info.
how to display pop up and check username and password.
I have only username. and want to check and grab the password from the database. It is BEFORE LOGGING IN. so I don't think the build-in asp.net functions could be used, right?
I have a folder with username and password over it.I wanna make a page where i can access files under that folders in .net and be able to download them.How to code that in VB.net?
Currently I am storing my username and password (passwordFormat="SHA1") credientails in my web.config. I would like to figure out how to access them in an xml file that I have stored in my App_Data directory rather than the web.config file because I do not want my application restarting everytime I manually add a user (small list of 5 authorized users for the CMS section).
I was curious how some of you are sending out an email to a new user, are you sending more then one email with username and link in one and then the password in another, are you sending everything in one email, are you sending an email to the new user at all?I'm curious because my web site is not a self registering web site, Only a supervisor can create a new user and then that user gets an email. I'm trying to figure out the best way to send the new user an email with their credentials to the site.the users are outside users (vendors) though their username is created by an internal employee
I want to validate Username and Password in a database. My database name is UsersLogin. The database table name is UsrLogin. The users are Mary with password: acd222 andJohn with password: dbd445 (field names : Usersand UserPassword)How can these 2 users login using their individual account details? And how can i lock them out after 3 wrong attempts
In my application i have login Page in that i have login Control of asp.net, when user clicks on submit button i am authenticating the user and and redirecting to default url.
now what i want is using address bar i want to authenticate the same process with out opening the login page and give user name and password in the login control. Directly i want to inject the username and password in the address bar and need the same functionality what the submit button does.
i have articles on net using post methods but i am not able to do this.
