Python 21 Basic Authentication I

This video is the 21st part of the Python tutorial series and focuses on building a basic authentication system. The speaker, Seyi Onifade, starts by creating a dictionary to store user information, including their username, password, and email address. He then defines functions for registration and login, which handle user input and authentication. The video also covers the concept of a While Loop to ensure that the user is prompted for input until they select a valid option. It further covers the use of conditional statements, input/output, and data structures.

Key Takeaways:
- Dictionaries are used to store user information.
- The registration function generates a unique user ID and stores the user's information in the dictionary.
- The login function prompts the user for their username and password, checks if they exist in the dictionary, and validates the credentials.
- A while loop is used to keep the system running until the user chooses to exit.
