Forgotton Password reset password not working - Umbraco 4.0.2.1

Hiya Guys,
Firstly like to appologise if this question has been asked before, if it has just point me in the right direction please.

OK I have an umbraco 4.0.2.1 site and I am setting up a role based protection members area on the front end site and the <asp:login> controls and such work lovely.

However the default <asp:PasswordRecovery> control I had no luck due to password being hashed. As when changing the membership provider settings in the web.config I get a YSOD saying

Provider cannot retrieve hashed password

OK then I thought I would create a custom .NET usercontrol to reset the password and send out an email.

With the code below it is definately resetting the password with a new password, however when i try to then login, the new password sent out doesn't work. What am I doing wrong?

Appreciate your input guys.

Thanks,
Warren

protected void btnRetrievePwd_Click(object sender, EventArgs e)
    {
        string newPassword = string.Empty;

        //Get user based on their login name (when not logged in)
        MembershipUser user = Membership.GetUser(Username.Text, false);

        if (user == null)
        {
            //User not found.......

            //Display message
            message.Text = "Username not found";
        }
        else
        {
            //Reset password
            newPassword = user.ResetPassword();

            //Need to email out the new password...

            string emailMessage = "Your new password is " + newPassword;

            //Send EMail
            sendEmail("[email protected]", user.Email, "Reset password for Telenor Objects", emailMessage);

            //Display message
            message.Text = "Email sent with new password";
        }

Hi Warren,

I think this may be related to the double hashing bug:

http://umbraco.codeplex.com/WorkItem/View.aspx?WorkItemId=23320

I submitted a patch for this, which has been accepted into version 4.1.

I think the only workaround at this stage is to turn off password hashing.

Although I might double check that.

Cheers Tim :)
Hmmm not sure if I can go bleeding edge with this client's site and go with the 4.1 beta 2 release.

I'll run it past the guys at work and see what they have to say though.

Hi Warren,

Had the same last week. Change the line

newPassword = user.ResetPassword();

to

newPassword = Membership

.GeneratePassword(6,2)

bit hard coded but 6 is the length of your password and the 2 the amount of nonAlphanumeric digits

More info on msdn

Cheers,

Richard

Hiya Richard,
Did this definately work for you?

As I have just tried this and I am getting the new password sent in the email, but it still doesnt work with the login.
```
<add name="UmbracoMembershipProvider" type="umbraco.providers.members.UmbracoMembershipProvider" enablePasswordRetrieval="false" enablePasswordReset="true" requiresQuestionAndAnswer="false" defaultMemberTypeAlias="Another Type" passwordFormat="Hashed" />
```

Hi Warren,

Was watching speedskating yesterday so I made a mistake. You need to assign the new password to the member also. I am using the umbraco member objects for this. I know this is not the prefered approach but when using the default member objects you can set the password . I've used the code below:
```
 string newPassword = Membership.GeneratePassword(6, 2);
 
Member member = Member.GetMemberFromEmail([email protected]);
member.Password = newPassword;
member.Save();
```
Hope it works for you,

Richard

I've found this quite interesting, I originally (wrongly) assumed that to change a member's password, you would set set the password property, and it would work out the hashing or encryption, such as:
```
m.ChangePassword("password");
```
What I actually found was this just wrote the value straight into the database, and thus the user could not log on after changing the password, so, I found that using the helper functions, you could hash the password manually, this applies for members changing their password, creating new accounts, or an administrator having the ability to set a members password (outside of Umbraco's admin suite)

In this example, 1 is the fictional member ID!
```
m = new Member(1);
```
```
 MemberShipHelper mh = new MemberShipHelper();
```
```
 m.ChangePassword(mh.EncodePassword(txtPassword.Text, MembershipPasswordFormat.Hashed));
```

```
 string newpassword = GeneratePassword();
            member.Password = newpassword;
            member.Save();
```
If you wish to set the password directly, without using the MembershipProvider, this works and correctly hashed the password (GeneratePassword just does a Guid.NewGuid().ToString().Replace("-", "").Substring(0, 6) - but this could be anything.)
