Passwords Plus incorporates a feature that allows you to synchronize your passwords with an online cloud service that's encrypted as well. This is the easiest way to keep your passwords secure. If you have a problem with security, synchronize your passwords with the cloud service, reinstall the software and restore the content, then delete the items from the cloud.
For your problem, skip everything asked by the software, enter a master password, connect your account and synchronize your data and that's it.
