I want to send emails to users when the forget their passwords that prompt them to reset their passwords. I know this is debatable and was looking for a few good options/sug
Here's what I do:
I have reset_password table. When someone asks for a reset, they usually click a link on your site that says "forgot password" where they enter their email they registered with and your system sends a link. Of course you begin with finding out if the user is registered at all. by selecting from users where email = $_POST['email']. If they exist, make a randomly generated token, like
$token = md5($_POST['email'].time());
But as Buh Buh expressed in the comment below, you may want to use something a little less obvious to generate your token. crypt() can accept a salt pattern if you like.
Insert the request (email and token) in the reset_password table, then you send them a link like
http://www.domain.com/resetpassword.php?token=
Then in that file you take the $_GET['token'] and cross reference it with the reset_password table. If the token is valid, you present them with a form that asks for their new password. Upon submit, select the user with the email address related to that token and update the user table.
