I have both KeyPassW and Internalz installed. The KP file is a "database.kdb" file. Perhaps I don't understand how to use either app. Thank you!
You can't open the .kdbx directly. You need to export the database to .xml with regular KeePass and the move that file over to the TP and import it with KeePassW. Then you can delete the .xml file.
To open a .kdbx file directly, there is a new WebOS app called KeePassGo: KeePassGo - KeePass database viewer
