The Dashlane extension available on the Chrome Web Store is compatible with any Chromium-based browser such as Brave or Opera.
Once you've installed the Dashlane extension, you should see a Dashlane D icon in your browser's toolbar.
If the Dashlane icon is green, you're logged in to your account.
If the Dashlane icon is orange, you're not logged in.
