Removing the remembered login and password list in SQL Server Management Studio

Question

I\'ve recently used our company\'s spare laptop (that has a general user set up) while mine was being repaired. I\'ve checked the \"Remember password\" option in SQL Server

Answer 1

In my scenario I only wanted to remove a specific username/password from the list which had many other saved connections I didn't want to forget. It turns out the SqlStudio.bin file others are discussing here is a .NET binary serialization of the Microsoft.SqlServer.Management.UserSettings.SqlStudio class, which can be deserialized, modified and reserialized to modify specific settings.

To accomplish removal of the specific login, I created a new C# .Net 4.6.1 console application and added a reference to the namespace which is located in the following dll: C:\Program Files (x86)\Microsoft SQL Server\130\Tools\Binn\ManagementStudio\Microsoft.SqlServer.Management.UserSettings.dll (your path may differ slightly depending on SSMS version)

From there I could easily create and modify the settings as desired:

using System.IO;
using System.Runtime.Serialization.Formatters.Binary;
using Microsoft.SqlServer.Management.UserSettings;

class Program
{
    static void Main(string[] args)
    {
        var settingsFile = new FileInfo(@"C:\Users\%username%\AppData\Roaming\Microsoft\SQL Server Management Studio\13.0\SqlStudio.bin");

        // Backup our original file just in case...
        File.Copy(settingsFile.FullName, settingsFile.FullName + ".backup");

        BinaryFormatter fmt = new BinaryFormatter();

        SqlStudio settings = null;

        using(var fs = settingsFile.Open(FileMode.Open))
        {
            settings = (SqlStudio)fmt.Deserialize(fs);
        }

        // The structure of server types / servers / connections requires us to loop
        // through multiple nested collections to find the connection to be removed.
        // We start here with the server types

        var serverTypes = settings.SSMS.ConnectionOptions.ServerTypes;

        foreach (var serverType in serverTypes)
        {
            foreach (var server in serverType.Value.Servers)
            {
                // Will store the connection for the provided server which should be removed
                ServerConnectionSettings removeConn = null;

                foreach (var conn in server.Connections)
                {
                    if (conn.UserName == "adminUserThatShouldBeRemoved")
                    {
                        removeConn = conn;
                        break;
                    }
                }

                if (removeConn != null)
                {
                    server.Connections.RemoveItem(removeConn);
                }
            }
        }

        using (var fs = settingsFile.Open(FileMode.Create))
        {
            fmt.Serialize(fs, settings);
        }
    }
}
