Imagine um ladrão tentando repetidamente diferentes chaves para entrar em sua casa. Isso é como um ataque de força bruta, em que os hackers tentam milhares de combinações de senhas para obter acesso ao seu site.
Isso parece assustador, mas, felizmente, você pode defender seu site facilmente, como nós fazemos, limitando as tentativas de login. Isso limita o número de vezes que alguém pode tentar fazer login antes de ser bloqueado, dando aos hackers quase nenhuma chance de entrar.
Este artigo o guiará pelo processo de configuração de limites de tentativas de login em seu site WordPress. Exploraremos por que isso é importante para a segurança do seu site e o orientaremos nas etapas, mesmo que você não seja um especialista em tecnologia.
Por que você deve limitar as tentativas de login no WordPress?
Um ataque de força bruta é um método que usa tentativa e erro para invadir seu site WordPress.
O tipo mais comum de ataque de força bruta é a adivinhação de senhas. Os hackers usam software automatizado para continuar adivinhando suas informações de login para que possam obter acesso ao seu site.
Por padrão, o WordPress permite que os usuários digitem as senhas quantas vezes quiserem. Os hackers podem tentar explorar isso usando scripts que inserem combinações diferentes até adivinharem o login correto.
É possível evitar ataques de força bruta limitando o número de tentativas de login com falha por usuário. Por exemplo, você pode bloquear temporariamente um usuário após 5 tentativas de login com falha.
Infelizmente, alguns usuários acabam bloqueados em seu próprio site do WordPress depois de digitar a senha incorretamente várias vezes. Se você se encontrar nessa situação, siga as etapas do nosso guia sobre como desbloquear o Limit Login Attempts no WordPress.
Dito isso, vamos dar uma olhada em como limitar o número de tentativas de login no WordPress.

Como limitar as tentativas de login no WordPress
A primeira coisa que você precisa fazer é instalar e ativar o plug-in Limit Login Attempts Reloaded. Para obter mais detalhes, consulte nosso guia passo a passo sobre como instalar um plug-in do WordPress.
A versão gratuita é tudo o que você precisa para este tutorial. Após a ativação, você deve visitar a página Settings ” Limit Login Attempts (Configurações ” Limitar tentativas de login ) e, em seguida, clicar na guia “Settings” (Configurações) na parte superior.
As configurações padrão funcionarão para a maioria dos sites, mas vamos orientá-lo sobre como definir as configurações do plug-in de segurança para o seu site.
Para estar em conformidade com as leis do GDPR, você pode clicar na caixa de seleção “Conformidade com o GDPR” para exibir uma mensagem em sua página de login. Você pode saber mais sobre o GDPR em nosso guia sobre WordPress e conformidade com o GDPR.
Em seguida, você escolherá se deseja ser notificado quando alguém for bloqueado. Se desejar, você pode alterar o endereço de e-mail para o qual a notificação será enviada. Por padrão, você será notificado na terceira vez que o usuário for bloqueado.
Depois disso, role a tela para baixo até a seção Local App (Aplicativo local), onde é possível definir quantas tentativas de login podem ser feitas e o tempo de bloqueio que o usuário terá de esperar antes de tentar novamente.
Primeiro, você precisa definir quantas tentativas de login podem ser feitas. Depois disso, escolha quantos minutos o usuário terá de esperar se exceder esse número de tentativas fracassadas. O valor padrão é 20 minutos.
Também é possível aumentar o tempo de espera depois que o usuário tiver sido bloqueado um número especificado de vezes. Por exemplo, as configurações padrão não permitirão que o usuário tente fazer login por 24 horas depois de ter sido bloqueado 4 vezes.
Recomendamos que você não altere a configuração “Trusted IP Origins” por motivos de segurança.
Não se esqueça de clicar no botão “Save Settings” (Salvar configurações) na parte inferior da tela para armazenar suas alterações.

Dicas profissionais sobre como proteger seu site WordPress
Limitar as tentativas de login é apenas uma maneira de manter seu site WordPress seguro.
A primeira camada de proteção do seu site WordPress são as senhas. Você deve sempre usar senhas fortes em seu site WordPress.
Pode ser difícil lembrar de senhas fortes, mas você pode usar um gerenciador de senhas para facilitar esse processo. Se você administra um site WordPress com vários autores, veja como forçar senhas fortes para os usuários no WordPress.
Se a sua página de login do WordPress ainda estiver sendo atacada, outra camada de proteção que você pode adicionar é o Google reCAPTCHA para login do WordPress. Isso ajudará a reduzir ainda mais os ataques DDoS.
Nenhum site é 100% seguro porque os hackers sempre encontram novas maneiras de contornar o sistema. Por isso, é fundamental manter backups completos do seu site WordPress o tempo todo. Recomendamos usar o Duplicator ou outro plug-in de backup popular do WordPress.
Se você tiver um site comercial, recomendamos enfaticamente que adicione um firewall que cuide de ataques de força bruta e muito mais. Usamos a Sucuri para garantir nossa segurança e, se algo acontecer com nosso site, a equipe deles será responsável por consertá-lo sem custo adicional.
Para obter mais dicas sobre segurança de sites, não deixe de consultar nosso guia definitivo de segurança do WordPress.
Esperamos que este tutorial tenha ajudado você a aprender como limitar as tentativas de login no WordPress. Talvez você também queira ver nosso guia sobre como adicionar perguntas de segurança à tela de login do WordPress ou nossa seleção especializada dos melhores plug-ins de página de login.

Is there another way than a plugin? E.g. using htaccess or similar component? I have my own server and would like to have this limit on my site. However, I already have relatively enough plugins and would not like to add more. So I’m looking for a way to do it without a plugin.
WPBeginner Support
We do not have a recommended way without a plugin, a snippet would be fairly complex which is why we recommend the plugin. We also recommend taking a look at our list of how many plugins can be installed on a site to help remove your fear of having too many plugins

Thanks so much for this very helpful article on a plugin to stop the huge number of brute force attacks our site has endured recently. I’ve just installed it, using your easy to follow step by step guide to its settings. Can’t wait to see how it works!
Also followed the link to password managers. Thanks to your comments, I’m going to try LastPass again. We’ve been using Dashlane (free version) for a few years, but are frustrated by some of its rules. LastPass paid version sounds like a much better deal. Now to determine how to make the switch … easily!
Thanks again!

Good day! This is kind of off topic but I need some advice from an established blog. Is it tough to set up your own blog? I’m not very techincal but I can figure things out pretty fast. I’m thinking about making my own but I’m not sure where to start. Do you have any tips or suggestions? With thanks

It is not overly difficult to start a blog, we have a guide on how to start one here: https://www.wpbeginner.com/start-a-wordpress-blog/

I have Limit Login Attempts (yes, I need to update to something newer) and am being attacked all the time. I have added a new user as an administrator in an attempt to be able to access my own website without having to wait. But even then I have been kicked out before I can create any posts.
Does anyone have any advice please?
Shyam Chathuranga
Yep, you’re right. I’ve been using the Limit Login Attempts plugin for this whole time and recently, it started blocking all users instead of blocking the attacker based on his IP.
So, I guess I’ve to say bye for that plugin and use something else now.
Miguel
I recently installed WordFence to monitor my website security. It offers a feature for limiting login attempts. Consequently, I deactivated and deleted Limit Login Attempts Reloaded.
However, within WP Admin> Settings, there remains Limit Login Attempts. Do you know if that is installed by default with WP and regardless, how I can get rid of it.?
I believe that it’s overriding the settings in WordFence.
Thanks for your time,
Miguel

Howdy this is somewhat of off topic but I was wanting to know if blogs use WYSIWYG editors or if you have to manually code with HTML. I’m starting a blog soon but have no coding knowledge so I wanted to get advice from someone with experience. Any help would be greatly appreciated!
WPBeginner Support
WordPress comes with a WYSIWYG editor. It also allows you to add HTML to write posts.

I received the ‘exceeded maximum retries’ message today – but with an absolute correct password!
How can this be?
I just started setting up this WP site two days ago, it has no content aside from a free theme and a title. I installed login lockdown, but it is NOT activated.
it baffles me why there would be a BF attack on an obscure site name with barely 90 MB content…

Hi WPBginner’s Team,
Thanks a lot for creating such a huge and useful content for WordPress users like us. I always search for solutions at your website and also get the solution every time since last 2-3 years.
Today is the first time I am posting a comment for the above issue, I am using Limit Login Attempts plugin and it really helps me in keeping my website secure as per day I see 10-15 failed login attempts, but sometimes it is locked for 24 hours, which restrict us also. Is it possible to use Login LockDown also and block wrong attempts by IP, so that our genuine users are not blocked.
Is it possible to use Limit Login Attempts plugin and Login LockDown plugin at the same time on the same website?
Thanks

Hi Alam,
We recommend using Login LockDown alone and not with limit login attempts.

Hmm it looks like your site ate my first comment (it was super long) so I guess I’ll just sum it up what I wrote and say, I’m thoroughly enjoying your blog. I as well am an aspiring blog writer but I’m still new to the whole thing. Do you have any points for beginner blog writers? I’d certainly appreciate it.

With havin so much content and articles do you ever run into any issues of plagorism or copyright violation? My blog has a lot of unique content I’ve either created myself or outsourced but it seems a lot of it is popping it up all over the web without my agreement. Do you know any methods to help prevent content from being stolen? I’d certainly appreciate it.

Hi
Thanks 4 d article. Informative.
Is there any option to limit the login attempts without using any plugins?
YNS
Hi,
With the a bundle of trusted plugins (which at the same time offer multiple other security feature), It’s no longer that hard to protect WordPress sites from attacks like login attempt.
Those complaining about the feature not being in-built should realize the functionality extensions are meant to serve. The WordPress ecosystem is just scalable, I really like it. But need more partnership with powerful CDN provider. In countries like China, a good plugin like JetPack becomes useless because all the IPs it connects to are malicious to the Great Firewall.
This Blog is very useful, especially when promoting successful open source WordPress projects.
Brad
One of my sites get’s nearly 100 login attempts per month. Like many of you, I find it odd since it’s not an ecommerce site and we gather no user information. I installed Wordfence Security plugin which offers lock out options for any incorrect username as well as by IP and even entire countries.
It also has several other defenses which have proved to be invaluable. The web isn’t safe without some sort of protection. If you any of you know of a better one, please share.
Safe Programming!

No one has mentioned Jetpack, which has a module called Brute Protect. This blocks users from suspicious IP addresses automatically. It is based on a global network that can track spammers from all over the web.
Pete
Thank you for another the tip. I use BackupBuddy and I love that it automatically runs my backups but it also enables users to easily migrate sites to other servers. Especially going from a local host to a live server.
Donna
Its funny I get this email b/c I work up to 27 attempts at my site over night from all over the world.. I mean really what do they want I have a sewing and fashion blog? What they attempt to gain from this taking over my site and pay them?? I just changed my settings a few days ago prior to this article because I was getting quite a few hacks.. Now this am over 27 which is the most I have ever seen.
Connor Rickett
Is that a question that really needs an answer? Because it prevents brute force hacking (or at least slows it way down).
Why WP doesn’t come with limited login attempts out of the box, now THAT’S a question that I’d like to see a blog post addressing.
Iza
I am using Limit Login Attempts in combination with another great safety plug-in called WP-Ban. The Limit Login Attempts plug-in sends me an e-mail after second I believe unsuccessful login attempt with the IP of the user. I paste this user into Ban plug-in and next time, the user will not be able to try log-in at all. Just another layer of security against trolls.
Nika
Limit Login Attempts hasn’t been updated in over 3 years. It’s outdated. Login LockDown has poor functionality and why it’s recommended here I don’t know.
A few weeks ago I’ve installed WP Cerber instead.
It looks like a strong solution. It does all the things as expected.
WPBeginner Support
We do not agree that Login Lockdown has poor functionality. It does exactly what it says. We haven’t tested WP Cerber yet so we cannot comment on that.

I think it’s time WordPress should have configurable paths so that we finally can het rid of example.com/wp-admin. I saw requests for this, 8 years ago.
Jon Schear
I’ve used this a couple times. Brought the usual load of 50 emails an hour about lockout notifications down to 0.
Recaptcha is another good one, but much more difficult to implement.
Han Balk
I switched from LLA to Wordfence, because of all the extra security features it’s got.
Every Operating System has a feature to limit login attempts. I know WordPress is a CMS and not an OS, But it is a mature CMS and the WordPress community would greatly benefit of a buitlin login limitation that’s enabled by default. A lot of WordPress sites are “vulnerable” for unlimited login attempts, because they’re not properly protected and the owners are not security aware.
It can’t be that difficult to built in a login limitation and enable it by default in one of the forthcoming WordPress versions?
Howard
Limit Login Attempts has not been updated in a couple of years, and has some “holes” in it. I discovered this in my logs, where I found nearly 100 “lockouts” in a 10-minute period from the same IP. The lockouts were activated after the 2nd unsuccessful attempts, and were supposed to be for 72 hours. They were coming so fast that it was an effective DoS, and required some effort to get it stopped. It’s fairly obvious that the script kiddie has bypassed the lockout. The attacks from that IP address stopped when I was finally able to add it to the deny list in .htaccess.
.
I still use LLA for the limited but useful information and notifications, but I don’t rely on it to keep my site secure.
FranE
I notice this functionality on some of my sites, even though they don’t have the plugin installed. Is it included in certain themes? Maybe Genesis?
WPBeginner Staff
We are not aware of any themes including this functionality. Remember themes are not supposed to add functionality to your WordPress site. Functionality comes under plugins. May be it is something added by your web host?
Grayhambo
There appear to be some compatibility issues with this plugin with WP 4.0, as it hasn’t been updated in over 2 years. Can lock you out of the admin panel. If this happens, then you need to disable the plugin in the usual way, using something like cPanel access.
Joe
Seems to still work fine on all 10 of my wp sites
Torben Heikel Vinther
Sounds like a good and simple plugin, but why not use Better WP Security instead? BWS has a whole section about Limit Login Attempts AND many other security issues in one single plugin! In addition BWS was last updated 2013-8-24. Limit Login Attempts hasn’t been updated since 2012-6-1!
Editorial Staff
Torben, there are a lot of plugins that offers this functionality. Limit Login Attempts is a simple plugin that does one thing and does it real well. That’s not to say that BWS is a bad solution. It’s a very good solution (over 1 million downloads on the plugin already proves that).

I’ve been using the Limit Login Attempts plugin for my sites for a while. Now this plugin is outdated. Be honest. Did you use Limit Login Attempts on your site?

Since it has expired we have updated the article and replaced it with login lockdown plugin.

what about login lookdown plugin ? is it useful ? should i replace with this plugin ?

@abdelhafidcom That’s also good. It does the same thing. It just hasn’t been updated in a while.
