I'm talking about this screen, which insinuates that you can set the administrator password on this screen. Instead, it seems that the new password / confirm password inserted here is ignored.
Though in writing this, I realize you are probably expected to insert "admin" as the password in the current password field, and if you don't the update password mechanism doesn't work.
All in all, quite a confusing experience for the first time user.
A) why require a default 'admin' password to set the new password in a fresh install. Can't we just set the new password?
B) if it's a common confusion that you'd use the email (I would be this is because the screen below suggests that you'll be using the admin password in the sign in screen, that's a very common sign in pattern, so it's normal to expect that's what you're setting up in this screen), it may be useful to users to either not ask for the password in this screen, or make it extremely clear in the following page that you need to use "admin" as the username in the login screen (or why not just pre-populate that field for us, so that it's crystal clear what we need to do?).
I only harp on about this because it caused me to spend 10 minutes reinstalling the system, and searching around until I found a random forum post that explained it.
That's very close to a "this doesn't work so I'm giving up and looking for another solution" experience.
Unfortunate, because you've got quite a nice software now that I'm using it, so it's a pity if people give up just because the install process isn't clear.
