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 database
user_db = {"username": "user1", "password": "securepassword123"}
def authenticate(username, password):
if username in user_db and user_db["password"] == password:
return "Authentication successful!"
else:
return "Authentication failed!"
# User input
input_username = input("Enter username: ")
input_password = input("Enter password: ")
# Authentication check
print(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.
