I am using sqlite3 in a linux machine and I am getting the database without username and password. Can I set a username and password for the same?

You can password protect a SQLite3 DB. Before doing any operations, set the password as follows. conn = new SQLiteConnection("Data Source=MyDatabase. sqlite;Version=3;Password=password;"); conn.
Checking Login Credentials with Python and SQLite f"SELECT username from users WHERE username='{username}' AND password = '{password}'; Now we have the ingredients for a simple Python script to check whether a username/password combination exists in the database and print a user message accordingly.
SQLite: Documentation. Activate the user authentication logic by including the ext/userauth/userauth. c source code file in the build and adding the -DSQLITE_USER_AUTHENTICATION compile-time option.
No, sqlite3 databases are very lightweight systems. They need no server and all data is stored in one file. A username/password is not supported by the sqlite/sqlite3 package.
In order to achieve simplicity, SQLite has had to sacrifice other characteristics that some people find useful, such as high concurrency, fine-grained access control, a rich set of built-in functions, stored procedures, esoteric SQL language features, XML and/or Java extensions, tera- or peta-byte scalability, and so forth.
(sqlite, when to use)
However, since it's only a file you can encrypt the file with a password to protect your data.

SQLite doesn't have a concept of username/password. It's just a single file based database.
However, on Unix you can protect your database from other users on the same machine by setting the permissions of the database file itself.
e.g. Allow only owner access
chmod 700 /path/to/sqlitedb
If it's used in a simple web application then the web application will provide the control.
