The sId package provides some forms (templates) and some logic. You’ll get a fully-functional login-register system. You’ll be able to configure your routes and other settings like validators, callback functions and messages.
This package is simpler than User Accounts so you’ll be able to take a clearer path in learning. Also it’s more advanced than accounts-ui so you’ll learn how to prepare your own forms and how to connect it all together.
The main sId feature is that it is not dependent on any routing system (with examples of routes configuration) It is also very simple to configure and style.
blog post about it (with example configuration and tutorial):
Let me know about all bugs. Thanks.
