title: Devise email only signup - rails
body: <p>Within a rails app i'm working on. I'm trying to add the ability for users to signup simply by entering their email address and then confirming their account via the confirmation email. I don't want the user to have to enter in any password. <strong>How would I go about doing this?</strong> </p>
  
  <p>This example is useful, but requires for the user to enter a password: <a href="https://github.com/plataformatec/devise/wiki/How-To:-Email-only-sign-up" rel="nofollow">https://github.com/plataformatec/devise/wiki/How-To:-Email-only-sign-up</a></p>
  
  <p><strong>Should I just automatically use one password for all users?</strong> </p>
