I think @theymos, has something to say about Email here.
Topic: Email security notificationsI added email notifications for some security events:
Whenever your password is changed (except by an administrator), you will get an email about it.
Whenever your email is changed (except by an administrator), your old email will get an email about it with a link to lock your account. The link is valid for 14 days.
Let me know if you find any bugs.
Maybe, your curiosity is answered in the post above.
