View 8 RepliesDoes anyone has a solution (sample code) for the following features:
Create a randomGuid/Cryptographically strong random number Send a unique URL containing the random number to the user's email address When confirmed, the user is asked to change password
My provider is currently parametrized this way:
[code]....
The security issues with this type of procedure have been discussed here before.
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 can recover my password but when I try to change my password to something a bit easier to remember it gives me:
Password incorrect or New Password invalid. New Password length minimum: 7. Non-alphanumeric characters required: 1.
I am using Membership provider.. I integrated the aspnet member tables into my database.
I need the user to enter password on a data entry form and validate it against the membership tables.
How can I do this. This is the set up. I have few fields and user enters those fields and also enters the password, and submits the form. It is kind of like signature... i am looking for something like..
If txtPassword.text = membershipprovider password
{
//do this...
}
I am using a custom membership provider with a custom ValidateUser method. The ValidateUser sends and additional parameter to authenticate my users (Username, Password, and Dealer). I created a custom stored procedure for ValidateUser to call. I copied over all my users from another table and encrypted all the passwords in the aspnet_membership table using the code below. My question is, how do I take the password the user enters in the login form and validate that against what is in my aspnet_membership Here is the code I used to encrypt the passwords (not even sure this was the right way to encrypt. Please tell me if I did this wrong):
public static string EncodePasswordNow(string originalPassword)
{
Byte[] originalBytes;

I use access membership prvider and it works. but I am unable to recover passwork. It says that "" membership provider doesn't support to get and zero password." It gives me the error in turkish and I translated it. Something like that. I am using the below code;

how can I do that?
I'm using the ChangePassword method of membership provider to change the password and one of the requirement before calling the ChangePassword is to retrieve the current password. But I'm getting error:
padding is invalid and cannot be removed
below is my web.config:

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.
I have this code for changing a user's password when they click the password reset button (with extra code to log to ELMAH so I can try to figure out what is going wrong).
This is in ASP.NET MVC 2, using the standard aspnet membership provider, with a simple View like this:
New Password: ______
Confirm Password: ______
[Reset] [Cancel]
The route to this view is `/Account/Reset/guid`, where guid is the user's id in the aspnet membership database.
The key portion of the code is where it calls `user.ChangePassword()`. You can see that it logs a message when successful. The problem is that for some users, the success message is logged, but they can not log in with the new password. For other users it logs the success message and they can log in.
if (user.ChangePassword(pwd, confirmPassword))
{
ErrorSignal.FromCurrentContext().Raise(
new Exception("ResetPassword - changed successfully!"));
return Json(new {
Msg = "You have reset your password successfully." },
JsonRequestBehavior.AllowGet);
}
The full code listing is:

Edit: Adding a bounty to try to get this solved. This is one of the most annoying problems on my issue list, and I have no idea how to proceed.
I using control Membership and profile for change Your password. It is error when i login again.
View 2 RepliesI've made a change to my web config membership properties and now I seem to be having issues changing my password. I originally had
minRequiredPasswordLength="7" minRequiredNonalphanumericCharacters="0"
I've change it to passwordStrengthRegularExpression="^(?=.{8,15}$)(?=.*[0-9])(?=.*[A-Z]).*" however it still keeps coming up telling me that I need at least 7 characters and one nonAlphaNumberic... I looked at my machine config and made some adjustments there so that
minRequiredPasswordLength="" minRequiredNonalphanumericCharacters="" were blank
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.
Do I need to make a Custom Membership Provider or is there another way?
I have a project using ASP.NET Forms Authentication and the Microsoft SQL Membership Provider. The website is DONE. I use this provider everywhere. (Register, Login, Forgot Password, etc...) Until now, my website users have not needed complex passwords. The users' passwords were really just pins. The user could select anything for a password in the past. I had almost no restrictions for this website because none of the data is private or personal. However I have received new requirements.
Here are the new password requirements:
Passwords must be at least 8 characters in length. Passwords must be created using 3 of the following 4 character types:
Uppercase
Lowercase
Numeric
Punctuation
Do not use your name or User ID in the password. Do not use old passwords again later. Passwords must be changed at least every 60 days. Passwords may not contain your User ID or any part of your full name. Password history retention will prohibit use of the last 24 passwords. Passwords may be changed by users only once in any 6-day period.
I realize I am going to have to modify all of the following pages: Register, Login, Forgot Password, etc... fortunately I stopped using the default controls a long time ago.
My first thought was that I need to write a Custom Membership Provider. I don't know how to make the standard provider to do most of this. I could write code to do.
Do I modify the aspnet_membership table? Should I add my own table aspnet_something? Can the user profile table be used for this problem? Do I need my own MembershipUser class?
How can I set up membership provider to only accept passwords that adhere to the following rules:
Minimum 6 characters
Contains at least one letter and number
Should be case sensitive
I'm using a website as a frontend and all users are authenticated with the standard ASP.NET Membership-Provider. Passwords are saved "hashed" within a SQL-Database.Now I want to write a desktop-client with administrative functions. Among other things there should be a method to reset a users password. I can access the database with the saved membership-data, but how can I manually create the password-salt and -hash? Using the System.Web.Membership Namespace seems to be inappropriate so I need to know how to create the salt and hash of the new password manually.

View 1 RepliesEvaluting the method signature, it is required to know old password while changing it.
membershipUser.ChangePassword(userWrapper.OldPassword, userWrapper.Password)
Is there any way to change password without knowing old one.
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.

View 11 RepliesI have a membership provider in my web.config with the passwordStrengthRegularExpression attribute set. I dropped an asp:CreateUserWizard in a page and tried to create a user with a weak password (ie didn't match the regex in the web.config). The validation fails and displays the message
Password length minimum: 7. Non-alphanumeric characters required: 1.
The message corresponds to the default password strength requirement. I know it's using the value I have set in the web.config to validate against but how do I change/set/override the error message that gets displayed when the validation fails?
