title: Wordpress login URL with prefilled login details
body: <p>Let's say the login URL for my WordPress site is <a href="http://www.mycoolwoordpresssite.com/login" rel="nofollow noreferrer">http://www.mycoolwoordpresssite.com/login</a>, and this is what a client sees when he follows the link:<br><br>
  <a href="https://i.stack.imgur.com/moV4m.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/moV4m.jpg" alt="enter image description here"></a><br><br>
  But in order to make it easy for my clients I want the User-Name and Password fields will already be filled with the credentials.
  for example, if I'll provide a link that goes something like this:
  <a href="http://www.mycoolwoordpresssite.com/login?user=simon?passwd=12345" rel="nofollow noreferrer">http://www.mycoolwoordpresssite.com/login?user=simon?passwd=12345</a>, The fields in the login page will already be filled up with: <br>
  <strong>User-Name:</strong> simon <br>
  <strong>Password:</strong> ***** // (12345)<br>
  And the only thing left for the client is to hit the "Log In" Button and tell his browser to save the password. It should look like:<br><br>
  <a href="https://i.stack.imgur.com/AzPeC.jpg" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/AzPeC.jpg" alt="enter image description here"></a><br><br>
  I know it is not the safest thing to do in terms of website security, but it will be used just for subscriber accounts without any privileges. </p>
