Otherwise display message to user .</li> <li>Generate a ( lengthy ) <code>Random String</code> .</li> <li>Save the <code>Random String</code> in the ( user ) table for that user .</li> <li>Make a <code>Link</code> and put <code>Email Address</code> and <code>Random String</code> in it .</li> <li>Make an email which includes the <code>Link</code> and send it to the <code>Email Address</code> .</li> </ul> <p>Now user receives the email and clicks the <code>Link</code> :</p> <ul> <li>Parse the <code>Link</code> to get <code>Email Address</code> and <code>Random String</code> .</li> <li>Validate <code>Email Address</code> and <code>Random String</code> .</li> <li>If the <code>Email Address</code> and <code>Random String</code> combination exists , continue further .
