How to Restrict Login Attempts to Improve Security

Introduction

By default, WordPress allows unlimited login attempts, making sites vulnerable to brute-force attacks. To protect your users and server resources, you can limit the number of failed login attempts—forcing attackers to wait or preventing them altogether.

Plugin Recommendation

While a Web Application Firewall handles this automatically, you can also install the Limit Login Attempts plugin to block IP addresses after a configurable number of failures. It thwarts automated cracking by rejecting further attempts for a set lockout period.

Note: This is a third-party plugin. BuddyBoss has not fully tested it, so compatibility and support come from the plugin’s developer. Visit their support forum for help: https://wordpress.org/support/plugin/limit-login-attempts/

Troubleshooting and FAQs

Q: Login attempts aren’t being blocked—what should I check?
A: Ensure the plugin is active under Plugins. Then, clear any caching layers (site, object, or CDN) and retry to confirm settings apply.

Q: I use another security plugin—will this conflict?
A: It may. If you already have rate-limiting or firewall rules, disable overlapping features to avoid double-handling login failures.
