User stories:

• As a user, I want to be able to login once and be able to have access to the platform for numerous hours until I have to login again.
• As a user, I would like to sign in both with Google Sign-on and with my email address and chosen password.
• As a professor, I want a simplified, quick sign-on process where my students can utilize their google accounts, diminishing the need to create a separate account for this platform, to access the Code-Sparks platform with a google authentication process.

Tasks:

• Finish setting up authentication middleware
• Implement sign up and login routes
• Design login and sign-up front-end pages
• Establish connection to Google Classroom API
• Finish setting up Google API connections
• Fetch class and student data

Acceptance Criteria:

• After logging in, the user should remain authenticated across different sessions without needing to re-login for a specified duration.
• If the session expires, the user should be prompted to log in again.
• Session tokens should be encrypted and stored securely.
• Users should be presented with both options (Google Sign-in and email/password) on the login page.
• Selecting Google Sign-in should redirect to the Google authentication page.
• Email and password login should validate user credentials against the platform's user database.
• Students should be able to access the platform using their Google accounts without requiring to create a new account.
• After signing in with Google, students should be automatically recognized as students in the platform's role-based access system.
• Non-student users (e.g., professors or admin) should also have an intuitive sign-in process without confusion.
