Enpass

Enpass is a cross-platform password management app to securely store passwords and other credentials in a virtual vault locked with a master password. 
Unlike most other popular password managers, Enpass is an offline password manager. The app does not store user data on its servers, but locally on their own devices, encrypted. Users can choose to synchronize their data between different devices using their own preferred cloud storage service like Google Drive, Box, Dropbox, OneDrive, iCloud, and WebDAV.
The mobile version is restricted to storing only 25 passwords free of charge, although more functionality is available for a price. The desktop version, however, is unlimited.
On November 2017, developers stopped issuing updates on BlackBerry platform and in December 2018, with the launch of v6, the company dropped support for Windows 10 Mobile. 
In 2016, Windows Central rated Enpass as the "Best App for Windows 10 Mobile", and several technology publications like Computerworld, CNET, Macworld, iMore, Android Police, Android Central, and Android Authority have included Enpass in their list of best password managers.
