The official title for this technology is Preshared Key Authentication with Wired Equivalent Privacy. This name tells us a lot. We are not really truly authenticating someone using this approach, we are just ensuring that they possess a piece of information, the preshared key (password).

After all, having potentially sensitive network data traveling through the air as radio waves immediately presented massive concerns.
