About

Autofill your password in browser by scanning QR code with Zero(formerly ID Guard Offline) app on your phone.

How does it work?

1. A QR code will show up when you open a web page with a login form.
2. Open Zero app(not this extension) on your phone and scan the QR code.
3. Choose the account.
4. Your login form on the web page will be filled automatically.

How secure is it?

When filling password from your phone to the web page, your password is encrypted with a one time encryption key known only by this extension and the app on your phone. It can never be decrypted during the transmission on Internet.

Unlike most password manager extensions, this extension does not save any passwords. Your passwords are stored on your smartphone with security chip and sandbox protection. No password can be sent to the browser automatically unless you scan the QR code with the app on your smartphone. That means, no malicious desktop program or website can steal your passwords without your awareness.
