title: How to transfer login information and automatically log to another website, when user click on link?
body: <p>I have hosted 2 website, these two website use same database to populate data. eg: users - table
  has user login details, both website users can access their login via this table.</p>
  
  <p>Now I want to do this:</p>
  
  <p>Before access both website they need to login. </p>
  
  <p>My "Website A" has link call "Read More" when user click on it, that user
  should be redirect to "Website B". Now I want to skip "Login" process from B website(because that user
  already loged in A). How to do that,</p>
  
  <p><strong>I got mind this option, but less security:</strong></p>
  
  <ol>
  <li>A website read more link as </li>
  </ol>
  
  <p>B_website/?username=abc&amp;password=123&amp;page=12</p>
  
  <p><strong>I guess this is not good option, what are the ways i can do this with keep high security?</strong> </p>
