Global proprity "user.requireEmailAsUsername" question

Hello,

What happens if this propriety “user.requireEmailAsUsername” is changed to true, does any body know the rules? Like for example do you need to delete the user that haven’t email as username? or even has super user does it have to follow the rule, and have a email on username?

Regards

edit: maybe @wyclif or @dkayiwa or @darius know anything about this topic?

It specifies whether usernames should be email addresses or any string

It does accept any input as email or any string, but for some reason it generates an error when attempting to create a new User.

My goal is just to find a way to include an email for the Users. Any tips?

It should be able to allow any username if the property is set to false, you might want to look at the logs to confirm what is invalid, could be something else.
