I want users of my website to Register with those things:UserName,Email and Password.

 

I am not asking about their email password,i want them to create a new password for their account,but when they register,how can they login,and how can i make a login app related to register info.,How to know the info of those who have registered in my website,and when i make a password field,i need it to have its charecters hidden like in other websites.

 

Thanks.
