Problem with JFBC password generation and ES registration

Hello all,

I would like to NOT require the user to set a password during ES registration. Since ES would not let me create a profile type without the password field, I had set its visibility to "hidden" during registration.

My HOPE was that JFBC's "generate random password" would work and therefore make it unnecessary to expose the password field to the user. However, at the end of registration (with the password field hidden), automatic login did not work and I saw an error on the fronted, "Password cannot be empty" (or something like that.)

So, question: is it possible to NOT have the user create a password at all, and rely on JFBC to do it for the user? Or is this not possible?

Thanks!
