Write a Python program to authenticate a user trying to log into a secure school lab terminal.

The program should:

• Prompt the user to enter their username
• Prompt the user to enter their password
• Display the message Access denied if the entered username and password combination is not valid
• Display the message Access granted if the entered username and password combination is valid
• Repeat this process until a valid username and password combination is entered.

You should use indentation as appropriate, meaningful variable name(s), and correct Python syntax in your answer.
