It's really simple. Go on the website (https://18891eaa.alpine-linux-web.pages.dev) and create a account. (Note, the only button for sign in which works is email, but if you click that it has all the other sign in options ready)
Once a account is created login (if you have to) and wait for the thing to boot. Press enter where you see boot: press enter.
Once you have seen localhost login: type in root. that should log you in.
Although there is no passoword, you can only access someone else's linux if you have their account.
This uses Clerk, supabase for syncing (which doesn't work right now, but I am planning to fix), and vanilla JS/CSS/HTML, no next.js or anything.
