How to Do Authentication and Accounts by Hand

The book shows of how to do it by hand and even if you might not do it in a different environment I think it's helpful to know how an authentication actually has to work on a base level. It also makes clear that this topic is quite hard to cover in just one book so Manning just has an extra book on authentication just in a general way. With warp you have to think about it how like would I do this there are some crates but I've found it depends on the environment but it's easy enough to actually do it yourself.
