All that security is great, but when I renewed mine, it got "lost" in the mail. I put it in quotes because it never showed any production steps, just a tracking number. My stupid assumption was that the tracking number was automatically generated for return of supporting documents. Since I applied online, I didn't need to send any supporting documents, so when nothing arrived, I was not surprised. Mind you, my passport did not show it had been produced. Fast forward a month or two later, I remembered I never got my passport, so I gave them a call. They told me it was produced a long time ago and mailed using the tracking number I already had. Since it had been over 90 days, the tracking number was no longer valid. USPS reuses their 400-digit tracking numbers for some reason. Anyway, the end result is I had to cancel my never-received passport and apply again from scratch, including paying for everything again. And the kicker is, since it was "lost" I could no longer apply on-line.
