You can have more than one KeePass database open at the same time.

You can open more than one database at the same time in KeePass. Each database opens in a separate tab. This can be useful in situations where you want or need to keep some passwords separate (e.g. personal and business).

When you have more than one database open, KeeFox will search for passwords and list login entries from all databases (unless you have changed the relevant "Finding entries" options).

You can control which database KeeFox saves new passwords to when the "Save password" panel is displayed.

You can tell KeeFox which database you want to open first when launching KeePass - just look in the Options/Advanced panel.
