Membership - How To Check If Password Answer Matches What Is Provided By A User
Jan 30, 2011
I simply want to know how to manually check if the value a user has provided for the answer to their security question matches their current answer on record. I want to use the build in support of the ASP.Net membership and membershipuser objects.
I see that via the passwordrecovery control that the actual answer can be returned. However I am currently not using this control and it would take a good bit to integrate it as it does not meet our user's requirements.
In a worst case scenario, getting the actual answer (like the passwordrecovery control does) and manually checking it in our application would be acceptable.
A best case scenario is some sort of API where I can pass in the user name and the answer to their security question that was provided and simply get an indication of whether answer was correct or not.

My company has some unique password policies (such as a pwd cannot be re-used for 6 months, aside from the must include #, special character, upper & lower case)Can anyone suggest how to go about ensuring that a new user's password complies with these policies (using forms authentication in .net 3.5 framework)?

I have a custom membership user class and custom MembershipProvider working against database. Due to security reasons the user passwords are stored in the database as hashed values. So my procedure
public override bool ValidateUser(string username, string password) is
{
//select hashed password from db
return (EncodePassword(password) == dbpassword)
}
[code]....

I'm dealing with a scenario where a legitimate user doesn't have a clue about his password, secret question or the answer. So, I was trying to create an admin tool that would help me in situations like these where the admin should be able to type in username and reset the password without having to know/enter answer to secret question. I understand that I need to make some changes to the web.config for this to work. I thought I made all the changes but my ResetPassword() requests are still not working.
Here's my web.config settings for the provider.

I would like to create a sync process between an ADSI table and aspnet Membership using Membership.CreateUser. However, I need to see if a user exists before importing. I can import as long as a user does not exist however I am having trouble checking if users exist and only importing if they do not. Here is my code so far.

There seems to be something wrong with the create user wizard?I am using hashed password storage. When I change it to clear storage I see the user's password is being stored as something completly different than what they typed in.Example: changeme1 now equates to something like: 4W*KQQ4%=SIf I use 4W*KQQ4%=S as the password to login with it works but changeme1 does not.When I use the reset password wizard it updates the password just fine and it works when I login next.Any clues what could be causing this?

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 .

How can I use Membership.GeneratePassword to return a password that ONLY contains alpha or numeric characters? The default method will only guarantee a minimum and not a maximum number of non alphanumeric passwords.

Am using ASP.NET membership authentication in a small website and i just noticed some thing funny during testing. Am trying to enable user to change their login password any time they wish, i dragged a change password control to the form, i changed the password for my test account, but now all passwords are still working.
I can login with the old password as well as the new password with this particular test account. If i try with any other random characters as the new password, i cant successfully login (which OK). But if type the old password, am able to login, if i type the new password, am still able to login, am finding this very strange.
