Agreed. Whenever I&#x27;ve made email addresses optional, it just means I can expect to do a bunch of manual &quot;forgot my password&quot; support. And it&#x27;s hard to justify responding with &quot;sorry, can&#x27;t help you since you didn&#x27;t input an email&quot; when you&#x27;re in the early stages of growth and your one active user&#x27;s remember-me session finally expired.<p>These days I prefer to require an email address. That way, the few users that want to opt-out can insert a bogus one.
