  I'll have a short presentation at the end of RADEXT which addresses this problem directly.  And shows how easy it is for bad actors to confuse naive users.

  I'll post a link to the presentation here when it's ready.

  In short, there is no practical way to onboard users securely via the method of "connect to an SSID, and click through the prompts".  The configuration MUST be provided to the user signed, and/or via an out of band method.
