Works with your other apps

Local apps can pair with Secret Keeper over IPC (unix socket / named pipe) and delegate encryption to it - keys never leave the vault. That is how the Tetatet Chat messenger integration works.

Installing the extension

Until the Chrome Web Store listing is live, the extension installs unpacked:

  1. Download the .zip and unpack it into a folder you keep.
  2. Open chrome://extensions and enable “Developer mode” (top right).
  3. Press “Load unpacked” and choose the unpacked folder.
  4. Pin Secret Keeper to the toolbar - the popup works like the app: create or import a profile with 12 words.
