title: securely storing login details to external services
body: <p>I’m making an app that performs tasks on other sites for you. </p>
  
  <p>Example - my app would login in to your theguardian.com account and check if you have any replies to your comments and perform an action if you do. </p>
  
  <p>I'm wondering how I should store, and read, the login details for the guardian.com in my app? Obviously I want to avoid plain text. </p>
  
  <p>I'm using rails and Postgres, my app is fully SSL. </p>
  
  <p><strong>EDIT:</strong></p>
  
  <p>I'm voting to close the question as it's obviously a bad idea and it  looks like people are going to tell me so many times. @jvillian has suggested a gem which will help encrypt properties on a model if I do want to avoid plain text, which may be of use to anyone who stumbles across the question.</p>
