Thanks so much for the feedback (both here and in the app). That's something we're looking into, and I totally understand it makes it hard for kids to use the app. Grasshopper is an Area 120 project (a part of Google) which is why that account system is currently used for syncing course progress and achievements between devices.

btw is there a login system you'd prefer? I'd love to forward any thoughts you have to the Area 120 leadership.

How about an anonymous login system that doesn’t require an email address and just generated a random userid / password? I’m thinking of setting up a Code Club at a local school and it would be great if kids could use it without having to provide any personal information whatsoever.

Thanks for the idea! Supporting things like anonymous login or username/password is definitely something we're considering. :)

freecodecamp.org is pretty awesome.
