INI file gets over written in Qt

[SiddhantR]

I am creating a config file which stores username, password and role of certain user. I use the following code.

void MainWindow::OnAssignButtonClicked()
    {
       QSettings settings("/root/configFile.ini", QSettings::IniFormat);
 
       QString userName = lineEditUsername.text();
       QString password = lineEditPassword.text();
       QString Role = comboBox.currentText();
 
       QList<QString> listUsername;
       QList<QString> listPassword;
       QList<QString> listRole;
 
      QVariantMap userPasswordMapping;
      QVariantMap userRoleMapping;
 
      listUsername << userName;
      listPassWord << Password;
      listRole << Role;
 
     for(int i = 0; i < listUsername.size() ; i++)
     {
       QString user = listUsername.at(i);         
       QString pass = listPassword.at(i);
       QString role = listRole.at(i);
 
       userPasswordMapping[user] = pass;
       userRoleMapping[user] = role;
      }
 
// Store the mapping.
      settings.setValue("Password", userPasswordMapping);
      settings.setValue("Role",userRoleMapping);
 
    }

void MainWindow::OnAssignButtonClicked()
    {
       QSettings settings("/root/configFile.ini", QSettings::IniFormat);

       QString userName = lineEditUsername.text();
       QString password = lineEditPassword.text();
       QString Role = comboBox.currentText();

       QList<QString> listUsername;
       QList<QString> listPassword;
       QList<QString> listRole;

      QVariantMap userPasswordMapping;
      QVariantMap userRoleMapping;

      listUsername << userName;
      listPassWord << Password;
      listRole << Role;
      
     for(int i = 0; i < listUsername.size() ; i++)
     {
       QString user = listUsername.at(i);         
       QString pass = listPassword.at(i);
       QString role = listRole.at(i);

       userPasswordMapping[user] = pass;
       userRoleMapping[user] = role;
      }

// Store the mapping.
      settings.setValue("Password", userPasswordMapping);
      settings.setValue("Role",userRoleMapping);

    }

To copy to clipboard, switch view to plain text mode 

The first time the value gets written correctly. However if I run the program again the value over writes the old values. Can some one please suggest me a solution here?
Thank You

You are calling setValue() so the value for that key is stored in the settings. Did you expect it to be different?

Ok so what change should I do?

I have no idea what you want to achieve.
