Answer 2

first, you should build an HTML page with a form, where users can sign in by typing their credentials, user and pass.
second you must attach an action to that form, a POST action, this is the most used, in order to send the data that the user entered to the server.
third you must handle this request by building a back end mechanism that checks the credentials with the ones that are stored in a database.
fourth, this back end mechanism must respond to the sign in request, positively or negatively, if the user exists or no.
fifth in order to automate this procedure you must build the sign up mechanism which is similar to the above(instead o checking, the back end logs an entry to the database, the new user) so that you don't have to input new user credentials by pure SQL statements.
