Dashlane: Securely Remembers All of Your Passwords
Now, moving forward considering the security of your data while setting up Dashlane. Dashlane will ask you to set up a master password when you set up for the first time. I recommend, Use a password which is unique and something you have never used.
So, this master is very important for the security of websites. As Dashlane is a robust password manager with a gorgeous interface. When Dashlane syncs the data from your computer to their server or sync data between your two or more devices, it encrypts the data using AES-256 encryption, which is the strongest encryption known.
This is very strong encryption, if in case hackers get the access to the data without a master password, they can’t do anything. So be cool!
