Vaulis Browser Extension
Autofill passwords, save new logins, and generate strong passwords — directly in your browser.
v0.2.2 · Manifest V3 · Zero-knowledge
Works with Chrome, Brave, and Edge today. Firefox requires a separate build.
Store submissions are in progress — for now, install manually in under 2 minutes.
v0.2.2 · July 2026
Install in 5 steps
Developer mode must stay on. Chrome, Brave, and Edge require Developer mode to load extensions not from their store. If you turn it off, Vaulis will be disabled until you turn it back on. This goes away once the extension is approved by the browser store.
Download and unzip
Click the download button above. Once downloaded, unzip the file — you'll get a folder called vaulis-extension.
Open your browser's extensions page
Chrome / Brave: navigate to chrome://extensions
Edge: navigate to edge://extensions
Firefox: navigate to about:debugging#/runtime/this-firefox
Enable Developer mode — leave it on
Chrome / Brave / Edge: toggle Developer mode in the top-right corner of the extensions page. Leave this on permanently — the extension won't load without it until it's approved by the browser store. Firefox: no toggle needed — proceed to step 4.
Load the extension
Chrome / Brave / Edge: click Load unpacked and select the unzipped folder.
Firefox: click Load Temporary Add-on… and select the manifest.json file inside the unzipped Firefox folder. Note: Firefox requires the separate Firefox download — the Chrome/Edge zip will show an error.
Pin the icon to your toolbar
Click the puzzle-piece icon (Extensions menu) in your browser and pin Vaulis. The 🔐 icon will appear on your toolbar and in password fields on login pages.

Autofill credentials

Generate passwords
Strong random passwords (8–64 chars) in the popup or directly on change-password forms.
🤖
AI field detection
Understands multi-step forms (AWS Account ID, Qantas FF number) and classifies extra fields automatically.

View vault items
Click any item to see username, reveal password, copy, and open the site.
🔄

When you log in with new extra fields, updates your existing entry — no duplicates created.
🛒 Store submissions in progress
