Is it a Virus?
✔ NO - Safe

Can I Disable?
✔ YES - Disabling will stop autofill, credential generation, and vault sync until re-enabled
Disabling may stop autofill and vault syncing across browsers
What is password-extension.exe?
password-extension.exe is the Windows-side executable for the SecurePass Password Extension. It coordinates encrypted credential autofill for supported browsers, manages local vault keys, and communicates with the SecurePass cloud vault via TLS. It runs in the background to provide seamless access and security checks.
password-extension.exe runs as a lightweight background service that talks to the browser extension via a local TLS API. It handles vault access, clipboard safety, and password prompts while isolating sensitive data in memory.
Quick Fact: The module uses end-to-end encryption for vault data; credentials never leave your device in unencrypted form and are guarded by a locally stored key.
Types of Password Extension Processes
- Background Service: Maintains vault synchronization and cryptographic operations
- Bridge to Browser Extension: Maintains the secure channel for autofill prompts
- Clipboard Handler: Manages safe copy/paste of credentials
Is password-extension.exe Safe?
Yes, password-extension.exe is safe when it's the legitimate file from SecurePass installed from official sources.
Is password-extension.exe a Virus or Malware?
The real password-extension.exe is NOT a virus. However, malware may imitate file names to mislead users.
How to Tell if password-extension.exe is Legitimate or Malware
- File Location:: Must be in
C:\Program Files\SecurePass\PasswordExtension\password-extension.exe or C:\Program Files (x86)\SecurePass\PasswordExtension\password-extension.exe. Any other path is suspicious.
- Digital Signature:: Right-click the file in File Explorer → Properties → Digital Signatures. Should show "SecurePass, Inc." as the signer.
- Resource Usage:: Normal usage is 2-15% CPU, 40-120 MB memory. Constant high usage when idle is suspicious.
- Behavior:: The process should launch when the extension is actively used. If it runs continuously without browser activity, it may indicate a malware variant.
Red Flags: If password-extension.exe appears in unusual folders (like Temp or AppData\Roaming), runs when browsers are closed, has no digital signature, or uses unusual resource spikes, scan immediately. Watch for similarly-named files such as "password-extension32.exe".
Why Is password-extension.exe Running on My PC?
password-extension.exe runs when you start SecurePass Password Extension in the browser or when the Windows service is configured to run in the background for autofill and vault synchronization.
Reasons it's running:
- Active Password Autofill: You're actively using the password manager to fill credentials or generate passwords; the extension keeps a live bridge for quick access.
- Background Vault Sync: The extension periodically syncs your vault data with the SecurePass cloud to keep credentials up to date.
- Browser Startup Integration: The extension can launch its background component at browser startup to provide immediate autofill support.
- Clipboard Operations: Clipboard monitoring is enabled to paste credentials securely, which keeps the process active during login flows.
- Security and Re-authentication: Periodic re-auth prompts or vault lock checks keep credentials protected, which may keep the process alive for a short window.
Can I Disable or Remove password-extension.exe?
Yes, you can disable password-extension.exe. Disabling will stop autofill and vault syncing, but you can re-enable it later to restore functionality.
How to Stop password-extension.exe
- Turn off in-browser autofill: Open browser extension settings for SecurePass and disable Autofill/Password Fill.
- Close the browser: Exit all browser windows to ensure the extension is not active.
- End the background process: Open Task Manager (Ctrl+Shift+Esc), locate password-extension.exe, right-click and End Task.
- Disable startup: Task Manager → Startup tab → Disable SecurePass Password Extension.
- Optional: uninstall extension: In the browser, disable or remove the SecurePass Password Extension from the extensions panel.
How to Uninstall Password Extension
- ✔ Windows Settings → Apps → Apps & Features → SecurePass Password Extension → Uninstall
