Any ddocumentation on the registration process?

I have 3 others helping me test the site out. This includes intentionally trying to break it etc etc.

Regarding the topic here – one of us intentionally ‘typed in the wrong password info’ and noticed that instead of going to (what I had thought would be) a custom, i.e., came with the Arcane theme, type of ‘lost or forgotten password’ type of page, I was notified that it just goes into the back end default WordPress login page (i.e., the white background with a little login window and the blue WP circle icon at the top of it, etc. etc.).

My question is, is there a custom login redirect for when this happens, or maybe somehow I didn’t properly set this up, any thoughts?… Like many I’m sure, if possible I’d prefer that a user, no matter what, is never being sent to anything WordPress per se; that is, I’m hoping there’s a redirect somehow that I haven’t yet found so as to prevent this (being sent over to WP stuff) from happening.

Hope I made sense here. I can grab a screen shot if that will help better explain.

Thanks and best,
