Guardikey
Install on Windows and start the full Pro suite free for 14 days — no account, no card. Your vault is zero-knowledge from the first launch, and the iPhone, Android and Mac apps that sync with it are rolling out now.
Up and running
in four steps
Download & install
Run the signed installer. Windows SmartScreen recognises the Apexium Technology signature; no sideloading or warnings to dismiss.
Set your master password
This single password derives every key on your device. It is never transmitted and never recoverable by us — so choose it well and save your recovery kit.
Import or add items
Bring your logins in from Chrome, Edge, Firefox or Brave in one pass, or start fresh. Everything is encrypted the moment it lands.
Add your phone when it lands
Sign in on the mobile app with the same account and your vault syncs across devices — only encrypted blobs ever move between them.
System requirements
- Windows 10 or Windows 11, 64-bit
- 200 MB free disk space
- 4 GB RAM (8 GB recommended for the local AI assistant)
- Optional: a FIDO2 / WebAuthn security key, Windows Hello biometrics
- Internet only for sync and subscription — the vault runs offline
Verify your download
Every Guardikey installer is code-signed by Apexium Technology. After downloading, you can confirm the publisher in the file's Properties → Digital Signatures, or check the SHA-256 against the value we publish on the release page:
SHA-256: published with each signed release
A matching signature proves the installer came from us and was not altered in transit.
