title: System users password has expired
body: <p>I have just tried to login to my db via sql developer as system so i can create a new user. It has come with an error that the password has expired.</p>
  
  <p>I have googled a bit but cannot see how to reset the system user password. I guess this is a security issue.</p>
  
  <p>My problem is how can I log in as system if the password has expired? How can I unexpire the password without logging in as System users. I seem to be stuck here in a loop where I cannot reset the password expiration.</p>
