Features:
* Autofill usernames and passwords on any website
* Copy username or password to clipboard with one click
* Unlock your vault directly from the browser popup — no need to switch to the desktop app
* Search and browse all your saved credentials
* Automatically shows matching credentials for the current site
* Badge counter shows how many credentials match the current page
* Available in 6 languages: English, Italian, French, German, Spanish, Portuguese
