Password-based authentication is a security mechanism where a user gains access to a system or application by entering a password that matches the one stored in the system's database.
# Example of password-based authentication in Python# Simulated user databaseuser_db ={"username":"user1","password":"securepassword123"}defauthenticate(username,password):if username in user_db and user_db["password"]== password:return"Authentication successful!"else:return"Authentication failed!"# User inputinput_username =input("Enter username: ")input_password =input("Enter password: ")# Authentication checkprint(authenticate(input_username, input_password))
This code snippet simulates a basic password-based authentication process by checking the entered username and password against a predefined user database.
