Description

Login LockDown records the IP address and timestamp of every failed login attempt. If more than a certain number of attempts are detected within a short period of time from the same IP range, then the login function is disabled for all requests from that IP address. This helps to prevent brute force password discovery and attacks.
The plugin defaults to a 1 hour lock out of an IP block after 3 failed login attempts within 5 minutes. This can be modified in options. Administrators can release locked out IP ranges manually from the panel.

Configure the plugin from Settings – Login LockDown

Nice plugin that adds protection against brute-force login attempts.

I can't believe after many many years of use I have not said thank you. I really appreciate this plugin. I recommended this recently to a friend who was delighted there was no advertising and upsell. Indeed! Great to know there are still some who go to the effort of sharing and updating because it's a nice thing to do.

This is brilliant. It's a must have for websites that attract a lot of traffic and which therefore will attract a lot of forced login attempts.

Thank you for this perfect plugin. You wouldn't believe how many login attempts you can get even on a brand new website w/o any external links so far. This is one of the plugins, I install everywhere.

I like this plugin and use it on a number of websites I am a webmaster for. In case it helps, here are some thoughts on how/why I have configured the plugin. I leave the first 3 entries as default (3,5,60). They seem ideal to me. I set Lockout Invalid Usernames? to YES. If they don't know the Username, why are they trying to login? I am careful, so I won't lock myself out. I set Mask Login Errors? to YES. Denies useful intelligence to people who are trying to login when they shouldn't. Why help them? I set Show Credit Link? to NO. I love helping people - and as it happens it's my professional work - however telling people about the plugin so they can protect their blogs also tells people who are trying to login when they shouldn't what security I am using. This is a more minor point, however it also falls under the 'need to know policy' - they don't.
