What is the CMDKEY Command?

The CMDKEY command is a Windows utility used to manage credentials (such as usernames and passwords) for accessing network resources. This command allows you to store credentials for remote servers or shared folders in advance, making it easier to access these resources without being prompted for authentication repeatedly.

Main Uses

  • Add Credentials: Pre-configure credentials for accessing remote resources.
  • View Stored Credentials: List all credentials currently saved in the system.
  • Delete Credentials: Remove credentials that are no longer needed.

How to Use the CMDKEY Command

Using CMDKEY, you can easily manage network credentials. Below is an overview of its basic usage with practical examples.

Basic Syntax

cmdkey /add:<target name> /user:<username> [/pass:<password>]
cmdkey /list
cmdkey /delete:<target name>
OptionDescription
/add:<target name>Add credentials for the specified target.
/user:<username>Specify the username for the credentials.
/pass:<password>Specify the password (leave blank to be prompted).
/listDisplay a list of all stored credentials.
/delete:<target name>Delete the credentials for the specified target.

Examples

  1. Add Credentials for a Remote Resource
    To add credentials for accessing a specific remote computer:
   cmdkey /add:192.168.1.100 /user:admin /pass:password123

Explanation: This command adds credentials for the IP address 192.168.1.100 with the username admin and password password123. The next time you connect to this resource, you won’t be prompted for authentication.

  1. View Stored Credentials
    To see a list of all credentials stored in Windows:
   cmdkey /list

Explanation: This command displays all the stored credentials, allowing you to see which remote resources you have saved authentication information for.

  1. Delete Credentials
    To remove credentials that are no longer needed:
   cmdkey /delete:192.168.1.100

Explanation: This removes the stored credentials for the IP address 192.168.1.100, requiring you to re-enter authentication information the next time you connect.

Use Cases for the CMDKEY Command

  1. Efficient Remote Server Management
    If you frequently manage remote servers, entering the username and password each time can be tedious. By using CMDKEY, you can save your credentials in advance, allowing for seamless and quick access to remote resources without re-entering authentication details.
  2. Using CMDKEY in Automated Scripts
    CMDKEY is particularly useful in batch files or PowerShell scripts where you need to automate remote resource access. By storing credentials, you can eliminate the need for manual input during script execution:
   @echo off
   cmdkey /add:192.168.1.101 /user:admin /pass:password123
   net use Z: \\192.168.1.101\shared

Explanation: This script adds credentials for 192.168.1.101 and maps the shared folder as the Z: drive, automating the connection without user intervention.

Things to Keep in Mind When Using CMDKEY

  • Security Risks: Entering passwords in plaintext using the /pass option poses a security risk. It is recommended to avoid hardcoding passwords in scripts and to store them securely.
  • Administrator Privileges: CMDKEY commands may require administrator privileges. Be sure to run the command prompt as an administrator when managing credentials.
  • Proper Credential Management: Regularly review and delete outdated or unnecessary credentials to maintain system security.

Conclusion

The CMDKEY command is an essential tool for managing credentials and streamlining authentication to remote resources. By pre-configuring authentication details, users can bypass repetitive login prompts and focus on their tasks. For network administrators and IT professionals, CMDKEY helps improve workflow efficiency, especially in environments where frequent remote access is required.
