I just received an email from a company:<p><pre><code>  - that is a multi-billion dollar company 
  - with whom I spend thousands of dollars a year as a customer
</code></pre>
that contained my password in plain text.<p>As a customer, of this specific company, what should I do?<p>As a customer, generally in the current era, with ~50 &quot;important&quot; online accounts, how can I protect against incompetent technology practices and avoid headaches?  What&#x27;re best practices for a tech-savvy consumer?<p>Thanks!
