Security plugin for WordPress with support for Fail2ban and Cloudflare. Tested with WordPress 5.5+.
This WordPress plugin provides security functionality and integration with Fail2ban and Cloudflare.
The WordPress slug is fail2wp.
The plugin is also available on wordpress.org
Basic security functionality includes:
- Disabling login with username (require e-mail address)
- Preventing user enumeration (?author=nnn)
- Less detailed error messages on login failures
- Minimum username length
- Blocking specific usernames from being used to register new users
- Requiring e-mail address matching for new user registrations
- Warning about new user role setting
- Blocking of portions or all of WordPress REST API
- Disabling of RSS and Atom feeds
- Removal of "Generator" information from HTML and feeds
- Detection of Cloudflare IP addresses for logging of actual IP addresses
The plugin also plays nicely with Fail2ban, which is an advanced way of blocking IP addresses dynamically upon suspicious behavior.

Fail2WP uses standard WordPress functionality to handle localization/locale. The native language localization of the plugin is English. It has been translated to Swedish by the author.
All logging to system logs (i.e. php.log or auth.log) is done in English.
This is a hard question to answer. There are no known incompatibilities.
