Username/password authentication in IOT Protocols - Mini Project: Build & Apply

Username/password authentication

📖 Scenario: You are setting up a simple username and password authentication system for an IoT device. This device needs to check if the user credentials are correct before allowing access.

🎯 Goal: Build a small program that stores a username and password, sets a login attempt, checks if the credentials match, and prints whether access is granted or denied.

📋 What You'll Learn

Create variables for username and password with exact values

Create variables for login attempt username and password

Write a condition to check if login attempt matches stored credentials

Print 'Access granted' if credentials match, otherwise print 'Access denied'

💡 Why This Matters

🌍 Real World

IoT devices often require simple username and password checks to allow authorized users to control or configure them.

💼 Career

Understanding basic authentication logic is important for DevOps roles managing device security and access control.

1

Create stored username and password

Create a variable called stored_username and set it to "admin". Create a variable called stored_password and set it to "iot1234".

IOT Protocols

# Create stored username and password variables
# Your code here

Need a hint?

Use simple string assignment like variable = "value".

2

Create login attempt variables

Create a variable called login_username and set it to "admin". Create a variable called login_password and set it to "iot1234".

IOT Protocols

stored_username = "admin"
stored_password = "iot1234"
# Create login attempt username and password variables
# Your code here

Need a hint?

Use the same string assignment method as before.

3

Check if login credentials match

Write an if statement that checks if login_username equals stored_username and login_password equals stored_password.

IOT Protocols

stored_username = "admin"
stored_password = "iot1234"
login_username = "admin"
login_password = "iot1234"
# Write if condition to check credentials
# Your code here

Need a hint?

Use and to combine two conditions in the if statement.

4

Print access result

Write a print statement that prints "Access granted" if access_granted is True, otherwise print "Access denied".

IOT Protocols

stored_username = "admin"
stored_password = "iot1234"
login_username = "admin"
login_password = "iot1234"
if login_username == stored_username and login_password == stored_password:
    access_granted = True
else:
    access_granted = False
# Print access result
# Your code here

Need a hint?

Use an if statement to print the correct message based on access_granted.
