Yes, you can change your password for a website, and Dashlane will automatically update the login in your vault. Then your login, with the updated password, is ready to autofill on your next visit.
Also, in your account settings for a website, you can choose to edit or change your personal information, including your password. For example, when you make changes to your password, a Dashlane pop-up appears. We ask if you want to update the login with this new password or create a new login for this website.
After you make a selection, you can select Edit in the next pop-up if you need to make additional changes. You're taken to your vault in the web app where you can view all the login's details or change some of your preferences. The pop-up disappears in 5 seconds or when you leave the page.
