I am wondering wether i cam make a website which has a join member button. So if the user presses that button it will take to a new page where user can sign in with with their email id and pass. [remember there is no option for create a new account] Only i have is sign in using you current email Id and password. or Facebook authentication or twitter authentication.
Is it possible to make so. i need to validate for cases like if user going a wrong email id and password, or wrong Facebook email id and password same for twitter.
Only the user should be able to login using their email address and password. Is it possible to make like that. Please let me now!! Any hits.. Helps every thing is appreciated!!!
