Dialupass is a widely recognized, lightweight password recovery freeware utility developed by Nir Sofer of NirSoft that extracts and displays forgotten credentials for virtual private networks (VPNs), Remote Access Service (RAS), and traditional dial-up connections stored on Windows operating systems.
While Windows provides the convenience of saving connection credentials automatically, it entirely obscures the actual password from plain view. If you lose track of the original password given by your Internet Service Provider (ISP) or network administrator, retrieving it manually from system files is exceptionally difficult. This tool solves that issue instantly by scanning the deep registry hives and configuration files where Windows stores connection parameters. Core Capabilities and Features
The application operates as a standalone utility, processing system data without relying on bulky background installations or third-party dependencies. Its core functionalities target administrative recovery and system migration:
Instant Credential Enumeration: Upon execution, the utility automatically searches and lists every configured VPN or dial-up network profile.
Complete Account Mapping: The tool reveals three key pieces of information for every connection: the exact User Name, the raw Password, and the associated Domain or ISP profile name.
Flexible Data Exporting: Users can highlight specific profiles to save the retrieved information or generate full data sheets in text, HTML, CSV, or XML formats.
In-Line Editing Capabilities: Unlike passive viewers, the tool features a configuration prompt that allows you to double-click profiles to update and correct outdated login information directly.
External System Forensic Recovery: Advanced configurations enable administrators to pull credential data from an unbootable, secondary instance of Windows connected via an external hard drive or partition. Supported Frameworks and Technical Scope
The tool interacts natively with core Windows network configurations. It targets profile structures created under standard internet communication frameworks: Profile Types Captured Protocol Profiles Affected Compatible Operating Systems
• Virtual Private Networks (VPN)• Remote Access Services (RAS)• Dial-up Internet Connections• ADSL/Broadband Connections
• PPPoE (Point-to-Point Protocol over Ethernet)• PPTP (Point-to-Point Tunneling Protocol)• L2TP (Layer 2 Tunneling Protocol)
• Windows 95 / 98 / ME• Windows NT / 2000 / XP• Windows Vista / 7 / 8 / 10 / 11• Windows Server 2003 / 2008
Note: Administrative elevation (Right-click “Run as Administrator”) is strictly required under newer Windows versions to access protected Local Security Authority (LSA) secrets and connection phonebooks (rasphone.pbk). The Antivirus “False Positive” Dilemma
When downloading or executing Dialupass, users frequently trigger critical alerts from security suites like Microsoft Defender, ESET, or Symantec, labeling the utility as a “Password Stealing Tool” (PWS:Win32/Dialupass) or “Hacktool”. Dialupass.cpp – GitHub
