Similarly, I know people who are incapable of communicating information via email and insist that they must talk on the phone or in person.<p>Situation 1: &quot;Hey can you call me?&quot; Sure, what do you need to talk about? &quot;The status of the Spark server.&quot; Okay.<p>Find a quiet place, place the call, debug connection problems so we can hear each other.<p>So what do you need? &quot;Is the Spark server up?&quot; Yes. &quot;Okay, thanks, bye.&quot;<p>Situation 2: Email to coworker: &quot;Hey the other day you said you said that the downloaded certificate is one factor, so with the password, that&#x27;s already two factors, and the rotating token would be three.  But we only need two, so that would mean we don&#x27;t need the rotating token now.  But the CTO is confused then -- how was the certificate securely transmitted in the first place, to the point that we can count it as a second factor?&quot;<p>Two days later: Coworker approaches me: &quot;So what was that email about?&quot;<p>(Only exaggerating a little bit.)
