Send files using extra security. The user needs to authenticate before gaining access to the files.
The standard protection allows you to e-mail files securely. If, however, you would like some additional protection, then it is possible to encrypt the files with a password. The recipient is sent the password separately either via e-mail, telephone, SMS or WhatsApp, and afterwards gains access to the files. This way the files are only accessible to the individual who has personally received the password.
