How to protect the database from users?

Question

Python

Hello!
I recently developed my python application using a postersql database to store personal login information.
I compiled it into an .exe file and everything seems to be good.
The problem is that if an advanced user decompiles and digs into the code, he will get a connection to the database and be able to pull the entire database.
How can this outcome be avoided?
thanks for the advice

Answer 1

Write a simple API, requests to which will be sent by the client application, and, accordingly, process all requests on a secure server, and make sql queries from it, but by no means store the data for database authentication directly in the code ...
