title: I have never set any passwords to my keystore and alias, so how are they created?
body: <p>As I was going through some posts on the Internet learning more about <em>signing your Android app</em>, I got post like <strong>how to sign the app</strong>, and something about <strong>what if you have lost your keystore file or password.</strong></p>
  
  <p>The question I am here to ask is that, I have never created a keystore, or its alias, or its password, so how on this earth can I forget it?</p>
  
  <p>I know that for Android we use the password <strong>android</strong>, so, if the password is by default android how can one forget it? (I'm sure there must be some other way to create new keystores).</p>
  
  <p>Finally, if android is the default password, <strong>what is the default alias?</strong></p>
