You can see the devices you've added to your account in any Dashlane app. You can also see when each device was added to your account and last used. Go to your Settings and select Manage Activity. You'll find Settings in the My Account menu in the web app and the side or bottom menu in other apps.
You'll see a globe for the Dashlane browser extension, an Android icon for Android mobile devices, and an Apple icon for iPhones, iPads, and the macOS app.
Tip: You can rename your devices in the web app or Safari or iOS (Apple) apps.
