ハッカーやその他の悪意ある行為者は、しばしば管理エリアからWordPressウェブサイトに侵入しようとします。だからこそ、WordPressの管理画面を保護することはとても重要なのです。
少人数のチームであれば、チームメンバーが使用するIPアドレスのみに管理者アクセスを制限するのも良い解決策のひとつです。これはハッカーの侵入を防ぐことができ、私たちのWordPressセキュリティのトップヒントの一つです。
この投稿では、IPアドレスによってWordPressの管理者アクセスを制限する方法を順を追って説明します。
なぜIPアドレスでWordPressの管理者アクセスを制限するのか？
WordPressのウェブサイトを運営しているなら、ウェブサイトのセキュリティを真剣に考える必要があります。WordPressのコアソフトウェアは非常に安全ですが、ハッカーや総当たり攻撃から身を守るためにできることは他にもあります。
ハッカーは、あなたのサイトをダウンさせるだけでなく、収益や評判を損なう可能性があります。データを盗んだり、サイト訪問者にマルウェアを配布してGoogleなどのブラックリストに登録されることもあります。
ハッカーをブロックし、WordPressのセキュリティを向上させる賢い方法の1つは、WordPressの管理エリアを不正アクセスから保護することです。
管理エリアへのアクセスが必要なのがあなたや信頼できる少数のユーザーだけなら、wp-adminとWordPressログインページへのアクセスをあなたのチームのIPアドレスに制限するのが良い方法です。
各チームメンバーは、各拠点の特定のIPアドレスを使用してWordPressサイトに接続します。他のIPアドレスへのアクセスをすべてブロックすれば、ハッカーがあなたのユーザー名とパスワードを知ったとしても、サイトにアクセスすることはできなくなります。
代わりにエラーメッセージが表示される：禁止されています。このリソースにアクセスする権限がありません。
IPアドレスでWordPressの管理者アクセスを制限する方法を見てみよう。
IPアドレスでWordPressの管理者アクセスを制限する方法
まず最初に行う必要があるのは、WordPressサイトにログインするために必要なすべての人が使用しているIPアドレスのリストを作成することです。複数の拠点で作業している人がいる場合は、それぞれのIPアドレスを収集する必要があります。
SupportAllyのようなサイトにアクセスすれば、IPアドレスを知ることができる。
リストを作成したら、サイト上のファイルを編集する必要があります。FTPクライアントまたはホスティングサービスのファイルマネージャーアプリを使用する必要があります。FTPを使用したことがない場合は、FTPを使用してWordPressにファイルをアップロードする方法のガイドを参照してください。
ソフトウェアを使用して、ウェブサイトの/wp-admin/フォルダに移動する必要があります。そこに移動したら、.htaccessファイルを探してください。これは隠しファイルなので、もし見えない場合は、ソフトウェアの隠しファイル表示オプションを有効にする必要があるかもしれません。
そのファイルがフォルダーに存在しない場合は、新規ファイルを作成し、.htaccessという名前で/wp-admin/フォルダーに保存してください。
警告ルートの.htaccessファイルを編集しないでください。サイト訪問者をフロントエンドから閉め出すことになります！本当に〜してもよいですか？
まず、バックアップとしてファイルのコピーをコンピュータにダウンロードしてください。
それができたら、.htaccessを編集し、以下のコードをファイルに貼り付ける必要があります：
AuthUserFile /dev/null
AuthGroupFile /dev/null
AuthName "WordPress Admin Access Control"
AuthType Basic
<LIMIT GET>
order deny,allow
deny from all
# whitelist Syed's IP address
allow from xx.xx.xx.xxx
# whitelist David's IP address
allow from xx.xx.xx.xxx
# whitelist Amanda's IP address
allow from xx.xx.xx.xxx
# whitelist Muhammad's IP address
allow from xx.xx.xx.xxx
# whitelist Work IP address
allow from xx.xx.xx.xxx
</LIMIT>
自分のチームメンバーの名前と一致するようにファイルを編集し、先ほど収集したIPアドレスを貼り付けて、xx.xx.xx.xxxと書かれている部分を置き換える。
ファイルを保存すると、そのIPアドレスだけがWordPress管理画面にアクセスできるようになります。
IPアドレスが変わったり、新しい場所からサイトにアクセスしようとすると、WordPressの管理エリアからロックアウトされることを覚えておいてください。新しいIPアドレスを/wp-admin/.htaccessファイルに追加する必要があります。

My wp-admin folder doesn’t contain an .htaccess file. What am I missing.
WPBeginner Support
You would need to have your FTP or file manager show hidden files if you do not see it.

How to find my ip address for hiding wp-admin folder?
WPBeginner Support
There are multiple methods to find your IP, one of the simple ones would be to use a site like supportally.com

You have to enable
module authz_groupfile
“sudo a2enmod authz_groupfile”
and restart apache

Not working for me. Code restricting admin to get access even I put the ip in a whitelist.
Rostyslav
After this line, you must put a condition for permission to allow php files to prevent conflicts:
allow from all

I tried the .htaccess password protection method.
It works, but I tried it on a site with Woocommerce, but then my customers weren’t able to log in.
Just saying that because it seems no one has mentioned that it doesn’t work with sites that need customers to log in !
Miguel
Hello, thank you for the tutorial. Unfortunately, I have not been able to make this .htaccess file to work correctly because it is denying access to the only IP address I included, my own… I am certain I copied your code exactly and I typed my IP correctly. The .htaccess file was saved under: /wp-admin/.htaccess
Am I missing something? Thanks
Miguel
I must add that I am working on a localhost installation.
WPBeginner Support
Hi Miguel,
Instead of your IP address, try adding 127.0.0.1
That’s your localhost IP address. If adding the IP alone doesn’t work, then add the following line before the above code:
Require local管理者

how to block the access to wp admin???
Emaan Ali
Hi Guys,
I have blocked the wp-admin with .htaccess as mentioned in this article. But i am having one problem that my admin-ajax file is also being restricted on public site.
My wordpress theme uses much of admin ajax functionality and that I have put the IP limitation access on wp-admin folder so its not accessible for all IP’s.
Does anyone find the solution for this ? If so please share .
Thanks in advance

Hi, This seems really a helpful one. Maybe you could help me. Instead of whitelisting an IP can we allow access for specific countries in .htaccess file? Hoping you can help me. Thank you very much.
Bridget
Thanks! This was the only solution that worked for me after trying so many

Hi, This does work. I checked and am “forbidden” to login on any other computer. I can’t even see the login panel. However, I am still getting about 24 failed log in attempts per day from all different IP addresses. Any ideas how there getting around this? It’s some kind of brute force attack? Thanks, Scott.
WPBeginner Support
Yes quite possibly. Make sure your .htaccess password is a difficult one.
管理者
Scotty
Thanks. Your site has been very helpful. If you have moment maybe you could answer one more question. I followed your tutorials — and they worked. I blocked access to my admin folder with htaccess and added a password on top of that. I tested and even if people were to break the password, which they haven’t, they wouldn’t have access to the folder from any IP address except mine. However, I’m still getting about 12 failed logins per day. Any ideas what is happening and where to go to fix it? I was hacked once, but cleared the files out of my uploads folder.

Praveen
Many Many thanks sir, I have test this on my localhost system it works very well.
Kim
I tried this (after previously successfully password protecting my wp-admin directory and fixing the redirect error per your other article), but then I get a pop-up asking for a user name and password for the “WordPress Admin Access Control”. What user name and password am I supposed to be using for this new pop-up? Neither the wordpress admin logon nor the wp-admin directory logon work for it.
Thanks!
Kim
Oh, I believe I figured out the problem; seems to work as long as I make sure to have the added code at the very beginning.
Jordyn
I have a big problem
I did what you said about creating the .htaccess and putting in the code snippet. It didn’t work so I deleted the .htaccess file and now I can’t login to my dashboard! It’s just a white screen
Please help!!!
Thanks
Editorial Staff
That’s a fairly unlikely outcome. You deleted the .htaccess file in your /wp-admin/ folder correct?
管理者
Jordyn
All I did was create the file in my wp-admin folder and when it didn’t work I deleted it from the wp-admin folder. I’m not sure what happened but, after a crazy rabbit trail and many shots in the dark, I was able to correct the problem by adding to the top of my login.php file. I still don’t know what went wrong or why what I did fixed it…. but at least its fixed. I may try this again when I’m feeling brave.
Jordyn
it erased the code snippet
it was supposed to say “…by adding “” to the top…”
Jordyn
less than sign ? ob_start(); ? greater than sign

First I did not manage to make your password protect work
https://www.wpbeginner.com/wp-tutorials/how-to-password-protect-your-wordpress-admin-wp-admin-directory
at least this one works.
It is interesting, that I wp-admin page gets into an infinite redirect when I enter a wrong IP address, not my one.
The infinite redirect seems to be hence an authorization problem.
Raheem Khan
Hi WPB, I don’t think it will be working in Pakistan because every time we reset or turn of our DSL modem so the IP address automatically changes. if any other tip please reply me.
Thanks

yes it can be done on https, it’s just .htaccess

hi, how to make .htaccess with dynamic ip (non static ip)
my ip is always change xxx.xxx.xxx.12 xxx.xxx.xxx.453 xxx.xxx.xxx.076
please help…
Editorial Staff

You can harden your wordpress install via .htaccess whitelisting even if you have a dynamic IP address. You can whitelist a range of IP addresses using a /24 or /16 range. While this allows more access than if you always knew the IP you wanted to allow, it still prohibits access from almost the entire internet.
Just add /24 to the end of the allow from line to allow the whole class C subnet (256 IPs), or add /16 to allow the whole 65,536 range. i.e.
allow from xxx.xxx.xxx.0/24
will allow access to IP addresses from xxx.xxx.xxx.0 – xxx.xxx.xxx.255. and
allow from xxx.xxx.0.0/16
will allow access from IP addresses from xxx.xxx.0.0 – xxx.xxx.255.255
Kyle
You say not to do the root site’s .htaccess file…why is that? Because you just want to limit access to the /wp-admin folder?
So…if I wanted to have a WordPress site hosted externally but used as an internal company resource so that only people using IPs of our company could access it…if I edited the root folder’s .htaccess folder to only allow IPs from our domain…that would work the same way your /wp-admin fix is, but for the entire site, correct?
Editorial Staff
Yes Kyle, the reason why we said do not put this code in the root file because then it will limit your site access to only these IP as well. But if you are trying to make a site just for your company’s staff can access it only from work, then you would want to put the .htaccess file in the root folder.
管理者
Kyle
Fantastic…thank you for the quick reply!
Bill
Why just limit GETs? You might want to limit POSTs as well!
Darrin
Nice tip. I will be doing this.
Alim Bolar
Can I limit access based on other criterias? Like I need only my laptop to access a particular folder.. I could access it from anywhere so it would be difficult to specify an IP as my internet access would be based on DHCP. Is there a unique identifier for every machine or something like that that can be used as a criteria?
