Login Watchdog is one of the several NutsForPress plugins providing some essential features that WordPress does not offer itself or offers only partially.  
Login Watchdog include these very useful functions for your every-day secure and protection of your WordPress website:
<ul>
<li>Two Factors Authentication for administrators: after a successful login every administrator is asked to enter a validation code sent by email; you can also set an option to skip two factors authentication until IP does not change, which is extremely useful for administrators they need to login frequently from the same IP</li>
<li>Login Attempts Monitor: checks login attempts and blocks (temporarily or permanently) failed login attempts exceeding the limits defined</li>
<li>Daily Check Notification: sends a notification when a difference is found between your site WordPress core files and the original ones of a clean setup, or when other suspect files are found</li>
<li>Security Notification: sends a notification on administrator successful login, on change of role, on plugin activation, on administrator delete and on user temporary or permanent lock down</li>
<li>Disable XML-RPC: disables XML-RPC protocol to prevent brute force attacks</li>
<li>Disable Author Page: hides author archive page and hides user info via API REST, so that none can know the author name by his ID</li>
<li>Custom Login Errors: displays custom login errors instead of WordPress default</li>
</ul>
Login Watchdog is full compliant with WPML (you don’t need to translate any option value)
