SilentSilo

Fills and saves logins with the SilentSilo desktop app for Windows, macOS and Linux. You confirm every fill and save in the app.

SilentSilo fills your saved logins into web pages and saves new ones, together with the SilentSilo desktop app on the same computer: version 1.4.0 or later on Windows or Linux, 1.5.0 or later on macOS. Without the desktop app the extension cannot fill or save anything. HOW A FILL WORKS 1. On a login page, click the SilentSilo button in the toolbar. 2. The extension asks the desktop app which logins are saved for this site and shows their names and usernames. 3. You pick one. The desktop app shows a confirmation naming the site and the login, and you confirm with Windows Hello, Touch ID or your security key. 4. Only then does the app send the username and password, and the extension writes them into the two fields on the page. SAVING A LOGIN Type the username and password on the page, click the SilentSilo button, then "Save this login in SilentSilo". The desktop app shows the site and the username and saves the login only when you press Save there. WHAT THE EXTENSION KEEPS Nothing. It holds no key and no copy of your logins, and it does not store the username or password it fills or saves. A fill goes only into the page you clicked on, and a save only to the desktop app. Your silo is unlocked in the desktop app, not in the browser. MATCHING BY SITE A login is offered on the site it was saved for: the same address, with or without "www.". A look-alike address matches nothing, and the popup warns that the page may not be the site you think. You can still search all your logins on purpose; the desktop app then tells you that the login was saved for another site before you confirm. WHAT IT ASKS THE BROWSER FOR - Native messaging, to talk to the SilentSilo desktop app on this computer. - Active tab and scripting, to reach the tab you clicked the button on, only then, and only in its main frame. No access to all sites, no script that runs on every page, no storage, no network requests. BEFORE YOU START - Install SilentSilo for Windows, macOS or Linux from silentsilo.com and open your silo. - In SilentSilo, turn on Settings > Browser extension. - Fills are confirmed with Windows Hello on Windows, Touch ID on a Mac, or a security key on any of them. Add one for the silo under Settings > Unlocking. LANGUAGES English, Romanian, German, French, Spanish, Italian, Portuguese (Brazil) and Polish, following the browser's language. NOT IN THIS VERSION Filling cards or addresses, and filling forms inside frames. OPEN SOURCE The extension and the desktop app are open source under the AGPL-3.0: github.com/silentsilo/browser and github.com/silentsilo/desktop.
