Sign up and login workflows in No-Code - Mini Project: Build & Apply

Sign up and login workflows

📖 Scenario: You are creating a simple sign up and login system for a small website. This system will help users create accounts and then log in using their credentials.

🎯 Goal: Build a clear step-by-step workflow that shows how users sign up with a username and password, and then log in using those details.

📋 What You'll Learn

Create a data structure to store user accounts with usernames and passwords

Add a variable to track the current logged-in user

Write the main logic to check user credentials during login

Complete the workflow by adding a confirmation step for successful login

💡 Why This Matters

🌍 Real World

Sign up and login workflows are essential for websites and apps to manage user access securely and personalize experiences.

💼 Career

Understanding these workflows is important for roles in web development, user experience design, and security.

1

Create user accounts data structure

Create a dictionary called user_accounts with these exact entries: 'alice': 'pass123', 'bob': 'qwerty', and 'carol': 'abc123' to store usernames and passwords.

No-Code

# Create the user_accounts dictionary with usernames and passwords
# Your code here

Need a hint?

Use a dictionary with usernames as keys and passwords as values.

2

Add current user tracking variable

Create a variable called current_user and set it to None to track who is logged in.

No-Code

user_accounts = {'alice': 'pass123', 'bob': 'qwerty', 'carol': 'abc123'}
# Create current_user variable and set it to None
# Your code here

Need a hint?

Use None to show no user is logged in yet.

3

Check login credentials

Write an if statement that checks if the username input_username exists in user_accounts and if the password input_password matches the stored password. If both are true, set current_user to input_username.

No-Code

user_accounts = {'alice': 'pass123', 'bob': 'qwerty', 'carol': 'abc123'}
current_user = None

# Check if input_username and input_password are correct
# Your code here

Need a hint?

Use if with in to check username and compare passwords.

4

Confirm successful login

Add a final if statement that checks if current_user is not None. If true, set a variable login_status to 'Login successful'.

No-Code

user_accounts = {'alice': 'pass123', 'bob': 'qwerty', 'carol': 'abc123'}
current_user = None

input_username = 'bob'
input_password = 'qwerty'

if input_username in user_accounts and user_accounts[input_username] == input_password:
    current_user = input_username

# Add confirmation for successful login
# Your code here

Need a hint?

Check if current_user is set and then assign login_status.
