Thank you for contacting us. There is no way to have multiple databases for a single mSecure account. mSecure was also designed for a single user at a time. Unfortunately, we also do not currently provide cross account sharing features at this time. If you'd like to have separate mSecure information, you will need to use separate mSecure accounts and purchase separate mSecure licenses. Thankfully, we are working on sharing features to allow you to share mSecure information with multiple mSecure accounts in the near future though.
Note: you need to reinstall mSecure 5 in order to be able to sign in to different accounts. Also, you can always create a backup file of your current mSecure information and use that backup file to restore the information in any other account. Here are some backup and restore guides you can use if needed: https://support.msecure.com/en/support/solutions/36000114421
