How to access passwords in C# using the Microsoft Webservices extension? [closed]

If your goal is to access the Web credentials in the Credential Manager in Control Panel, Microsoft.Exchange.WebServices.Data.WebCredentials is not applicable because it is used for Exchange server authentication and does not access the Windows Credential Manager.

You need to use the PasswordVault class to meet your needs. For detailed steps, please refer to the following:

1: Create a new console application project based on .NET8.0 in VS.

2: Right-click the project in Solution Explorer and click Unload Project.

3: In the pop-up .csproj file, change <TargetFramework>net8.0</TargetFramework> to <TargetFramework>net8.0-windows10.0.19041.0</TargetFramework>:

4: Save and right-click the project and click Reload Project.

5: Add the following code:

using Windows.Security.Credentials;
 
class Program
{
   static void Main()
   {
       var vault = new PasswordVault();
 
       try
       {
           // Get credentials from Credential Manager
           var credential = vault.Retrieve("example.com", "Your_user_name");
 
           //Get username
           string userName = credential.UserName;
 
           // Get password
           string password = credential.Password;
 
           Console.WriteLine("username: " + userName);
           Console.WriteLine("password: " + password);
       }
       catch (Exception ex)
       {
           Console.WriteLine("Unable to get credentials: " + ex.Message);
       }
   }
}
