This plugin modifies the standard login process for a popular content management system, allowing users to authenticate with their email address. It is designed for site administrators who want to simplify the login experience for their users or enforce specific login methods for security.

Email-based authentication: Users can log in by entering their account's email address, eliminating the need to remember a separate username.

Configurable login methods: Administrators can choose to enable or disable the use of email addresses, usernames, or a combination of both for logging in.

Selective username restriction: An option exists to specifically prevent login via the 'admin' username while still allowing other usernames, which can help mitigate common brute-force attack vectors.

Simple setup: The plugin works immediately after activation, requiring no complex configuration to enable the basic email login functionality.

Centralized settings: All configuration options are accessible from a single settings page within the admin area for easy management.
