Maintaining secure authentication across remote sessions is vital for organizations relying on Remote Desktop Protocol (RDP). In this article, you'll learn how to change a password on Remote Desktop using a variety of techniques suitable for technical users—ranging from keyboard shortcuts to administrative tools and automation scripts.
A fundamental challenge when working within RDP sessions is that the local system often captures system-wide keyboard shortcuts like Ctrl + Alt + Del. To overcome this, Microsoft provides a session-specific alternative: Ctrl + Alt + End.
Ctrl + Alt + End emulates Ctrl + Alt + Del within a Remote Desktop session. This combination opens the Windows Security screen, allowing access to multiple options including:
This is the recommended method for domain-joined users and for remote servers where GUI access is enabled.
This method requires:
In minimal or headless environments, this method might be unavailable due to restricted GUI features.
For environments with limited keyboard functionality—such as thin clients, virtual machines, or tablet-based access—the Windows On-Screen Keyboard (OSK) offers an alternative way to simulate Ctrl + Alt + Del.
This method works regardless of the physical keyboard limitations and is particularly useful in virtual environments where USB passthrough is restricted.
Command-line methods are ideal for IT administrators , allowing scripted or remote changes without navigating through GUI menus. This is particularly helpful when managing multiple user accounts or automating password rotation.
The net user command is a simple and effective tool:
net user username newpassword
Requirements:
Example:
net user admin SecurePass2025!
Use this carefully—passwords passed in plaintext can be exposed via command history or process monitoring tools.
Avoid scripting net user with plaintext passwords unless it is within a secure, encrypted deployment framework (e.g., PowerShell DSC or encrypted credential vaults).
PowerShell offers modern, object-oriented control over user accounts, both in local machines and in Active Directory environments.
This cmdlet allows secure password changes on standalone or non-domain machines:
Set-LocalUser -Name "johndoe" -Password (ConvertTo-SecureString "N3wSecureP@ss" -AsPlainText -Force)
Requirements:
To change a domain user's password:
Set-ADAccountPassword -Identity "johndoe" -NewPassword (ConvertTo-SecureString "NewDomP@ss123!" -AsPlainText -Force) -Reset
Additional best practices:
Always avoid embedding passwords in plain text—use secure strings or secure vaults (e.g., Azure Key Vault, Windows Credential Manager).
Windows offers built-in consoles for managing users and resetting passwords efficiently, especially in Active Directory or multi-user terminal environments.
For local users:
For domain-joined environments:
ADUC also integrates audit logging and delegation capabilities, which is critical for IT compliance.
When GUI access is restricted, or you're automating password changes across systems, scripting offers a workaround to open the password change dialog.
Save the following content into ChangePassword.vbs:
Set objShell = CreateObject("Shell.Application")
objShell.WindowsSecurity
Running this script in the RDP session will simulate Ctrl + Alt + Del.
Run this in PowerShell or via Run:
explorer.exe shell:::{2559a1f2-21d7-11d4-bdaf-00c04f60b9f0}
This launches the same Windows Security menu where the Change a password option appears.
Note: These methods rely on shell access being permitted. GPO restrictions may block them.
When a password expires, the RDP client may reject login attempts without offering an option to reset the password—especially in older or restricted configurations.
In many RDP setups:
