[HANDS-ON BUG] Agent Course Unit 1 - Unit 1 Final Quiz - Login issue

**Describe the bug**
I am logged into Hugging Face but if I try to take the "Unit 1 Final Quiz" system asks to login. If user is already logged in and have option to "sign-out", why to take quiz one needs to login again? Even after trying "sign-out", clear browser cache, restart/shutdown system same warning message to login.

**To Reproduce**
1. Login to: https://huggingface.co/learn/agents-course/unit1/final-quiz
2. Click on "Start" then below pop-up display
Warning
Please log in to Hugging Face before starting the quiz!
4. Click on "Sign in with Hugging Face" then below message display"huggingface.co redirected you too many times"
