Dear Team,

I have configured SQLite data base successfully, it's for creating product based application in visual studio windows application.
and I am struggling to create password protection for the SQLite database. Also not able to protect the database. If open SQLite database in SQLite studio, password credentials does not asked.

Thanks in Advance.

What I have tried:

SQLite Software downloaded and installed, but set password not visible in SQLite studio application.
