Hi!

I have recently come across the SeanPrasad Leetcode list and it has been very useful. The main problem is that every question has a checkbox which I believe is for the user to note that they have completed this question. I use multiple devices and when I open the list on another device, I can't see my progress. I believe this happens beacuse it is stored in the local storage of the browser. I would love to have an authentication system so that wherever I login, I know what questions I am already done with.

Thank you!
