Authentication System for Changing Email Address from Profile


On Internet, the essential required thing is security. Currently, there's no authentication system for changing the email address from the client profile. Preventing change the email address from unwanted access, it's must be required.

The scenario should be "If someone wants to change his/her profile email address, a confirmation email will be sent to his/her old email address. After granting the confirmation request from the old email address, the new email address will be replaced."

There can be another solution for it!
The email address field can be disallowed to edit and only changed by the system admin.

Please consider adding this feature.
