A 1Password-compatible password manager

passcards is a web, browser extension and command-line based password manager under development.

It uses the 1Password password vault format and is designed to be usable alongside the official 1Password apps.

The passcards apps are designed for use with Dropbox. To use them with an existing 1Password vault, you'll need to enable Dropbox syncing within the official 1Password apps.

passcards is available as a browser add-on for Firefox and Chrome, a web app and a command-line app.

See the passcards site for links to current releases.

The initial stable release of Passcards will target current stable releases of the major desktop and mobile browsers:

  • Firefox stable + current ESR release
  • Chrome stable
  • Internet Explorer 11 and later
  • Mobile Safari from iOS 7 and later
  • Safari from OS X 10.9

Support for older browsers may be possible in future.

Local development requires Node.js 0.10 and make. To build the CLI and web clients, clone the source and run make.

git clone
make all

The web client is a single page application. The Dropbox client keys in the source are configured to allow the app to be served from http://localhost:8000/webui/index.html . You can set up a server for this locally by running, from the root of a source checkout, python -m SimpleHTTPServer.

If you want to host the web app from a different location you will need to register your own Dropbox API keys from the Dropbox App Console. When registering a new app, you currently need to give it full Dropbox access permissions (though this requirement could easily be dropped if necessary) and enable the 'implicit' authorization flow.

The Firefox extension is built using the add-on SDK. A version of the SDK which produces addons compatible with Firefox 30 or later is included as a git submodule.

The Chrome extension is tested against Chrome 36 or later, though earlier versions should work.
