&gt; Mosh requires OpenSSH to run so no matter what, using Mosh is ALWAYS less safe than OpenSSH alone since all it does is add functionality on top.<p>Not sure I&#x27;d agree with this, since after initial session establishment, it completely replaces the functionality of OpenSSH in a way that guards against privilege escalation and authenticates every packet.<p>I do agree that there are some concerns with how &#x27;battle tested&#x27; it is, but not sure I believe this about &quot;audits&quot; since, I mean, the entire world was using OpenSSL to build the entire internet for ages and we just found out it was one guy scraping through the bug tracker for far too long.<p>The model of mosh is more secure than SSH, though its&#x27; session resumption could potentially expose a hole if someone has your token and session keys, they can resume your session.
