Browser Extension

Your vault, one click away in the browser

The full Credential Manager lives in a toolbar popup — search, copy and autofill on the sites you approve. Same zero-knowledge encryption, whether you use the extension or the web app.

In the extension

Everything you need, right in the toolbar

Your vault in a popup

The full Credential Manager, one click from your browser toolbar.

Autofill on approved sites

Fill saved credentials on the sites you explicitly approve — and nowhere else.

Global search

Jump to any credential across your folders without leaving the page you're on.

Favorites & quick access

Pin the credentials you reach for most for instant, secure retrieval.

Works as a web app too

Prefer a full tab? The very same encrypted vault runs in the browser.

Minimal permissions

Only storage, active-tab and scripting — no access to your broad browsing history.

Getting started

Up and running in four steps

  1. 1

    Add the extension

    Install DynoLocker for your Chromium browser and pin it to your toolbar.

  2. 2

    Sign in once

    Open the popup and unlock with your recovery phrase and any second factor you've set.

  3. 3

    Autofill as you browse

    Approve a site and let the extension fill your saved credentials there — encrypted end to end.

  4. 4

    Everything stays local

    The extension encrypts and decrypts in your browser, exactly like the web app. We only ever see ciphertext.
