When you create an encrypted volume, SecuBox prompts you to select the name and properties of the container file, as well as the password that would protect this file from access.
Whenever you mount the storage on your Windows Mobile device, SecuBox encryption software asks you for your password. Once you enter the password, the secure storage is mounted and you are able to access your encrypted volume.
Without your password, the encrypted data on your Windows Mobile device looks like a jumble of meaningless characters and your data is completely inaccessible to anyone who wants to get access to your private data.
