title: Storing private email addresses in my database
body: <p>My problem is not that I can't save emails to a database. Anybody can do that. Here is my question:</p>
  
  <p>When a user makes an account on my website, they get an ID, User, Password, and Email address data. For the password I hash it so that if somebody hacks my website they wont see the real passwords. However, isn't having a bunch of email addresses saved, unprotected (like the users) a security risk? </p>
  
  <p>I have never made a login system website before, and want to know if everybody else just leaves the email address unprotected in the database. (In other words, is it common just to save an email address to database as-is?).</p>
  
  <p>Thanks.</p>
