Hi Rob,

This is what I was talking about when I said it creates a key for the logged in user, not the new user.

I’ve underlined the part in red that I was concerned about.

Wes

I think that part is just a comment: https://serverfault.com/a/743551/598820

Aah, thank you, makes sense, I’m much more comfortable now. Thank you, much appreciated!
