Our Discourse site only uses 3rd-party authentication… we disabled the “local logins” feature. I got a complaint from a user that they couldn’t find the forgotten password link… which was surprising because we don’t use “local logins”.
It turns out that the account creation page suggests this when an email is already registered:
This made them think there was some link they were not finding on the site leading to confusion and frustration.
It would be better for this tip not to suggest the forgotten password link when “local logins” is disabled.
