Security :: Trying To Log In After A Mispelled Password?
Dec 1, 2010
I've implemented the Membership & Roles infrastructure of ASP.Net and it generally works well [in my ASP.Net 3.5 C# project].
However, testing is revealing something rather peculiar:
Start the web appDeliberately enter the wrong passwordTry again, this time with the correct password - fails to loginTry once again with the correct passwrod - login is successful Clearly this can't be the way it's supposed to work! I'm curious whether anyone else has observed this phenomenon, and if so, how did you fix it?
I am using Forms Authentication in a new ASP.NET 3.5 Application.I have created the Tables in my database and run the Web Site Administration Too.When I try to create a user I get a password error no matter what I throw at it and I am becoming sure of that this is a symptom of an a setup error and not a password problem.One of the things that I notice is that my aspnet_Applications is empty and I am not sure what is supposed to fill it.I have tried to delete all the aspnet tables and done the procedure again but with the same result.
I had been trying to solve this but there is a hidden key i wish someone point me to.
I had a simple membership database with users in first the Membership Provider configured for clear password to retrieve the original password .
Now a new requirement say that the password must be hashed and reset .
I configure the Membership password to hash , and Implemented the Reset Password Module.
My problem is as follow.
If the user is new registered user with the new configuration the password and the security answer is hashed.
also when I go and reset the password it continue to be hashed.
Now I thought that with new configuration if any previous user with clear text configuration , If he use the password Reset module , because my configuration now is hashed , I expected that the new password and security answer will be hashed . what happen is old user continue in clear text even if the configuration is hashed. so If I had new users everything is fine.
old users Membership Provider somehow know they had been stored in clear text and it keep change password and security answer in clear text . If I delete this user and create it , Membership Provider understand that everything will be hashed. I need to know how it know this , I need to migrate users not to delete and recreate users .
Also if there are no solution for that , I wish Microsoft Consider it in future cause it is a real user scenario, that can happen imagine a business system that related to membership user Id , deleting users and recreate them is not a solution .
I just begin creating a website for an organization. First page to be displayed in the login page. I dont have any knowledge in ASP.NET Security. On Login page, i want to display UserName field as disabled with the useralias of the user who currently logged into Windows. Password user has to provide and it should be that user's windows password.
How do i validate that password that user has entered is his windows password?
I am developing a shopping cart with asp.net and sqlexpress. I am using aspnet authentication components to create a backend page. I designed the site to let in only authorized users in.
Yesterday, I forget my password to login to backend and asked system recover my password. with recover password of the asp.net I was able to receive the temp password. I took that and logged in, of course asp.net forward me to password change component which I am having problem with.
Every time I change my password , password change shows that I was successfull but after clicking on the continiue button password change component comes back. I went to properties of password change component and entered the main default page as destination but it is not helping.
I close the IE clear the cache , even restart the machine. When I login always taking me to the password change page.
Is there a way to assign a value to the password and confirm password fields of the CreateUserWizard control programmatically when the page loads? The CreateUserWizard.Password property is read-only.
I would like to encrypt the password and store it in DB. And if user forgots the password and request for password i have to send him a dummy password to his mail id how can i implement this if any code available At the time of registration i have to encrypt or salt the password and save it to DB..
Am trying to open a .pps/.ppt file through my vb.net code.....due to secure reasons this file is password protected,
However i will not like the end user to put a password when accessing through my application.

I have been trying to encrypt password and found a code which is working with Access fine but as i have changed to SQL it is not decoding the encrypted text.. it amazes me..this SQl code is not letting me log on..
I am having a big problem trying to set the password for a login (MS SQL Server Management Studio).
I can create a new login and specify a password. Hitting "OK" reports no errors. Opening the newly created login shows that windows has automatically changed the original password to something else (I can tell because of the password length).
I have no idea why this is happening and have even tried reinstalling SQL.
can I change the password algorithm and still use the sqlMembershipProvider or do I have to create a new sqlMembershipProvider. If so, are they any step by step tutorials on how to do that.
I´m building a home page where logged in users shall buy products. To be able to get to the buy page the user already has to be logged in. But when he shall execute the buy he has to reenter his password again to check the user a second time. How do I check if his entered password matches his user password? I´m using the ASP Membership library and I have passwordFormat="Hashed".
Im trying to redirect different roles to different pages. Its working but the code I'm entering allows people through even with incorrect passwords. protected void Login1_Authenticate(object sender, AuthenticateEventArgs e)
We have a page where we ask users to enter only password in "enter password page" (the user name is taken in previous page).
The Issue is that when the page that asks user to enter password is opened in browser and when user enters password and clicks submit button, the browser does not ask the user to remember/save password,
Due to this when user opens that page next time, user have to retype the password.
You might have seen that in almost all sites whenever we open a login page, the browser asks weather we want to remember the password for next visit.
From the research done so far, we have found that browser remembers password only when the username and password textboxs are on the same page. But in our case we split down the username textbox and password textbox in two different pages.
Is there any way to let browser ask to user weather to remember/save password in "enter password page"?
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?
I have built an ASP.NET application that needs to be password protected. This application will be installed on multiple offline computers, and we need to make sure that when being installed it requires a password. But even if it requires a password, someone can easily copy the database and the published folder and duplicate the application on their system right?
I need a way to prevent this. It should only work on laptops that we have installed it on.
