My users occasionally forget their usernames. I suspect that your users do too. Heck, I forget my usernames once in a while! Fortunately I never forget my email address. Why must users login with their username when an email address is just as unique? Keep your users coming back with hassle free authentication.
By enabling both this plugin and the Authentication - Joomla! plugin, a user can login using EITHER their username or their email address.
By enabling this plugin while the Authentication - Joomla! plugin is disabled, a user can login using ONLY their email address (plus password, of course)
ATTENTION: This plugin does not alter the wording of your login page or your login module. You must implement a simple output override to accomplish the login module label in my attached screenshot.

Fill in the form as follows:
Language Constant: MOD_LOGIN_VALUE_USERNAME
