@JaredSnider-Bitwarden would you mind taking a look at this and letting me know if I'm on the right track? One piece I haven't been able to work out is "The create account section should react to environment changes if a user changes from an env where open registration is enabled to one where it is disabled" - it seems I have to refresh the page to get it to pick up the latest config.
