You can enable two-factor authentication by accessing "two-factor authentication (2FA)" under the "Settings" menu after you Sign In.
It is a simple best practice that adds an extra layer of protection on top of your user name and password. When a user signs in to Dropmysite, they will be prompted for their user email → address and password (the first factor- what they know), as well as for an authentication code from the device (the second factor- what they have.) Taken together, the two factors provide increased security for your resources.
It must be installed on your mobile device. Please download it now.
