How do I use the new wallet? I start it up and it asks for a email and password.
Yes, this is pretty confusing. The same for usnake - it asks for user/password, but it is unclear where do you get them from.
I suppose the right way is to sign up first in web wallet, then to log in using those credentials both to uwallet ant to usnake. At least this is what I did, and it worked

I did sign up for the web wallet and I tried to use that info to login but it does not work for me. I tried two different email address/password and it did not work either time.
