Hi,

We need to restrict users to not register or add the same email or mobile phone that another user already have. 3 Years ago in another topic, you say that is in the product roadmap to add this feature, but this don't happend.

Acoording to the helpdesk answer, is users responsability not using duplicate emails or mobile phones, this approach is wrong, you say that the weakest link have the security in theirs hands. This solution don´t resolve the problem that someone impersonate a user and recover the paswword.

Is there any way using a trigger or modify part of the code or modify a store procedure or a function to mitigate this?

Regards,
