Prevents All Changes to Profile

I tried this plugin but had to uninstall it because new members quickly started to complain that they can reset their passwords. Any attempt to make changes to the profile, such as change of password, results in an error which asks the user to enter the email address. But with email address greyed out, they can’t. Thus new user is left frustrated and without the option to change the generated password, which means he’s not coming back.
