title: Populate form in iframe of external website
body: <p>I am trying to write a php page that will load several different websites in different iframes. Several of those sites will need the user to login. What I need to do is basically allow the user to only type in the username and password once and then populate all the other forms (that are basically using the same user-pass pair for logging in)</p>
  
  <p>Now i know that since those are external sites you don't have access to the DOM and XSS is not allowed and all, but i was wondering if theres actually any other way to achieve that.</p>
  
  <p>Somebody actually suggested me to simulate keypresses and have a javascript that will basically go from field to field and essentially type in the username and pass but after doing some research I dont think thats possible since you can only simulate the event and not the actual keypress so...any other suggestions?</p>
  
  <p>NOTE: I have also checked <a href="https://stackoverflow.com/questions/3158761/pre-populate-external-website-form">this</a> but agreeing with the other sites/domains is not an option in my case!</p>
  
  <p>Thanks -- Mike</p>
