Secret Vault by Balog Ferenc

Secret Vault fills your saved logins into web pages, and can save new ones from the pages you sign in to.

Where your logins come from
- Your own Secret Vault server (sign in with your account, including two-factor codes)
- An API token, for a single collection or a few items
- The Secret Vault desktop app, connected through the browser's native messaging (the app holds the PIN)

Private by design
- End-to-end encrypted: the server stores only sealed data, and the extension opens it on your device.
- Nothing is sent to any third party, and there is no tracking or analytics.
- Fills only on the site that matched, only after you click or use the shortcut.
- Saving logins is off by default. If you switch it on, the extension asks for permission to see the sites you sign in to.

Also included
- One-time codes (TOTP), copy and fill
- Several accounts and sources at once
- English, Hungarian and Russian

You need a Secret Vault server account, an API token, or the desktop app to use it.
