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
Add the extension
Install DynoLocker for your Chromium browser and pin it to your toolbar.
- 2
Sign in once
Open the popup and unlock with your recovery phrase and any second factor you've set.
- 3
Autofill as you browse
Approve a site and let the extension fill your saved credentials there — encrypted end to end.
- 4
Everything stays local
The extension encrypts and decrypts in your browser, exactly like the web app. We only ever see ciphertext.
