WordPress 4.5 added the ability to login using the registered user’s email address in place of the username. When this plugin is active, the ability to login using the email address in place of the username is removed, and the label of the input field is changed to reflect this.

No Login by Email Address

Removes the ability to login using the email address instead of the username.

MJP Security Tools is a focused hardening plugin that does four things well:
<ul>
<li>XSS Database Scanner — scans every table for <code><script></code>, <code><iframe></code>, <code>onclick</code>, <code>javascript:</code> and other injection patterns</li>
<li>POST Request Log — records all POST data (passwords masked) with IP, user agent, and URL for CSRF/audit detection</li>
<li>Failed Login Log — tracks every failed login attempt with username, IP, and timestamp</li>
<li>File Permission Checker — verifies WordPress root files and directories have safe permissions, checks for missing <code>index.html</code> files and SVN working copies</li>
</ul>
What this plugin does NOT do (because WordPress core already handles it):
<ul>
<li>SSL enforcement — use <code>FORCE_SSL_ADMIN</code> or let WordPress 5.7+ auto-redirect</li>
<li>Password strength — WordPress core enforces strong passwords since 4.3</li>
<li>Login rate limiting — use a dedicated plugin like Limit Login Attempts Reloaded</li>
<li>Version number hiding — marginal benefit, not worth the complexity</li>
</ul>
Upgrading from v1.x:
<ul>
<li>The admin page has moved from jQuery UI tabs to native WordPress nav tabs</li>
<li>SSL forcing, password enforcement, login throttling, version hiding, admin username changing, database prefix randomization, password reset, and .htaccess generation have been removed — WordPress core and dedicated security plugins handle these better</li>
<li>PHP sessions replaced with WP transients for flash messages</li>
<li>Log data is now stored as JSON instead of serialized PHP</li>
<li>The Javacrypt client-side crypt(3) script has been removed</li>
</ul>
