WordPressのユーザー名を変更できなくてイライラしているのは、あなただけではありません。
新規サイトを立ち上げる際、この問題に出くわしたことがあり、本当に頭痛の種であることを知っています。しかし、ログインユーザー名を変更する方法はあります。
このガイドでは、WordPressのユーザー名を変更する3つの方法をご紹介します。
WordPressのユーザー名を変更することは可能ですか？
ユーザー名はWordPressでは変更できません。WordPressのプロフィールを編集したり、フルネームを変更したりする際に、このメッセージが表示されます。
初心者のWordPressユーザーにとって、これはイライラさせ、混乱させることでしょう。WordPressのユーザー名を変更するには、いくつかの回避策があります。
この記事では、WordPressウェブサイトのユーザー名を変更する3つの方法を紹介します。以下のリンクから使いたい方法にジャンプできます：
方法1：新規ユーザーを作成し、古いユーザーを削除する（プラグインなし）
WordPressのユーザー名を変更する最も簡単な方法は、希望するユーザー名と管理者権限グループで新規ユーザーを作成することです。
ただし、現在のアカウントで使用しているメールとは別のメールアドレスを使用する必要がある。
注： Gmailをお使いの場合は、ユーザー名の後にプラス記号（+）を追加文字で挿入できます。
例えば、あなたのメールアドレスがmyname@gmail.com の場合、myname+wordpress@gmail.com というメールアドレスを使うことができます。同じメール受信トレイに届きますが、WordPressはこれを別のメールアドレスとみなします。
新しいアカウントを作成したら、WordPressアカウントからログアウトし、作成した新しいユーザーアカウントでログインする必要があります。
次に、WordPress管理エリアの ユーザー ” すべてのユーザーページに移動し、古いユーザー名の下にある「削除」リンクをクリックして削除します。
古いユーザー名を削除すると、WordPressはそのユーザーが作成したコンテンツをどうするか尋ねます。
本当に〜してもよいですか？ ‘Attribute all content to’ オプションをクリックし、作成した新規ユーザーを選択します。
その後、’Confirm Deletion’ボタンをクリックして、古いユーザーアカウントを削除してください。
WordPressユーザー名の変更が完了しました。以前と同じメールアドレスを使用したい場合は、新規ユーザーのメールアドレスを変更してください。
方法2：更新された簡単なユーザー名を使用する（プラグイン方式）
WordPressのユーザー名を変更するもう一つの簡単な方法は、プラグインを使用することです。WordPressのプラグインを使いすぎることを心配されている方は、WordPressのユーザー名を変更したらプラグインを削除してください。
最初に行う必要があるのは、Easy Username Updaterプラグインをインストールして有効化することです。詳しくは、WordPressプラグインのインストール方法のステップバイステップガイドをご覧ください。
有効化した後、ユーザー ” ユーザー名更新ページに行き、変更したいユーザー名の横にある「更新」リンクをクリックするだけです。
新しいユーザー名を入力し、「ユーザー名の更新」ボタンをクリックするだけです。
変更をユーザーに通知したい場合は、まず「ユーザー通知を送信する」にチェックを入れてください。
これですべてです！これで、あなたのサイトからユーザー名変更プラグインを削除することができます。
方法3：phpMyAdminでWordPressのユーザー名を変更する（上級者向け）
この方法は、WordPressのデータベースに直接変更を加える必要があるため、少し複雑です。
WordPressサイトにエラーを引き起こす可能性があります。
しかし、WordPressのユーザー名やメールアドレスを忘れてしまい、管理者アカウントからロックアウトされてしまった場合など、設定ができない場合もあります。
まず、ウェブホスティングサービスのダッシュボードにログインして、phpMyAdminメニューを見つけます。
この例ではBluehostを使用しています。cPanelを使用しない別のホスティングサービスを使用している場合、ダッシュボードの外観は異なるかもしれませんが、phpMyAdminオプションは使用できるはずです。
あなたはBluehostのダッシュボードの中に入ったら、先に行くと ‘ウェブサイト’タブに移動します。次に、サイトを選択し、 ‘設定’ボタンをクリックします。
次に、クイックリンクのセクションまでスクロールダウンします。
その後、「phpMyAdmin」をクリックするだけです。
新しいブラウザータブでphpMyAdminが起動します。
WordPressデータベースがすでに選択されていない場合は、選択する必要があります。
WordPressデータベースのテーブルが表示されます。初期設定では、WordPressのデータベース・テーブルは、各テーブル名の前にwp_をプレフィックスとして使用します。データベースの接頭辞を他のものに変更している可能性があります。
左側のwp_usersテーブルをクリックしてください。そして、変更したいユーザー名の横にある「編集」をクリックしてください。
user_loginフィールドに新しいユーザー名を入力します。
完了したら、画面下の「Go」ボタンをクリックして新しいユーザー名を保存します。
これですべてです！これで、新しいユーザー名でダッシュボードにログインできるはずです。

Thank you so much for this post! The ‘add new user’ then ‘delete old user’ & ‘attribute to new user’ worked for me.
And I now have the plugin which also works.
FYI – when I changed the email address after adding new user, it took aaages for the confirmation email to come through to my Gmail from Wordpress.

Glad it worked, setting up SMTP can also help with email deliverability if someone hasn’t set that up yet.

That was really helpful. I was searching for the solution and some websites suggest to install a plugin, which is not the best solution for me,
because that would make my site slower.
Since I am familiar with PHP, so it would be better to use PHPMyAdmin in Cpanel.
And that’s what I did with the help of this article.
Thanks

Glad our article could help, in general a plugin should not slow down your site unless it is poorly coded.

NEVER USE “admin” or the domain name as a user, this is the first thing hackers use to get access to the backend.
WPBeginner Support
Thanks for sharing this, we agree that users should avoid using the username admin

Using phpMyAdmin worked like a charm for me. I wanted to change my username because I discovered while perusing Wordfence brute force activity on my site that my username had been used by a hacker.

Doing it in the database won’t wipe anything out like their orders if WooCommerce?

Thank You! php way worked perfectly!
Bonkarah
Appreciate the info given here. I was able to use PhpMyadmin to change the user name. But on logging in to my Wordpress site, the info on my dashboard is so limited. The new username that was there before i deleted the wrong one with Admin role had Author’s role. Could this be why I am not granted full access to my editing dashboard where I could add more users and edit normally?
Somebody help me out here. How do I get back to my full dashboard editing suite and change my role to Admin?

Why won’t your website let me create an account? When ever I try it says to try again with no explanation.

I have used the plugin ‘username changer’ and now my account is gone?! What happend and how can I undo this?
WPBeginner Support
Hi Linda,
Try to recover the password first. If this fails, then you can try resetting admin password via phpmyadmin.

I tried doing this to edit the nice-name attribute, so I don’t leak my user name on the Author’s page, and now my site only shows: Error establishing a database connection. Even after re-naming the field to its original value it doesn’t fix it. Any suggestions?

Thank you! Finding so much help for setting up my new WP account. I’m transferring an existing blog from Blogger. (And existing Google domain.) Any things you’ve already done on that would be great!!! I’ll be searcher your site a lot!

just successfully used the plugin to change my user name – it was really easy then just deleted the plug in – really really useful – thank-you

Hi i can not find username changer under users
Ripunj
You can simple do this without the plugin. You have to create a user, and for that you have to click on Add New button in the Users section, input the username whatever you want to and then assign the role of it to Administrator then log out. Now log in using newly created username and go into the same section that is Users and now can simply delete the old admin user.
Heather
Hi There. It did seem to work, but it did not attribute all the content. So my bio, my social media links, and Gravatar photo are gone. I can’t figure out how to get all that back.
Colin Crawford
Hi
I can’t get this to work, I have tried other tutorials and they say just the same.
I am in the right database as there is only one and I have edited the old admin username that was originally set up i.e. admin and it won’t allow me to login.
In the database it has clearly changed but when I try to login it won’t allow me. So using the old admin username gets me back in but how? it has been changed it doesn’t exist anymore….
If I view the Users in WordPress my new username is not there so where is it getting these details from?
I am truly baffled.

Gary Armstrong
You may want to try changing the password to your admin user within wordpress. It would be good to have another temp Admin level user in WP as a backup.
If you’re using phpmyadmin, open the password field, choose a new password and IMPORTANT! choose the MD5 function (or this will NOT work).
Once you change the password, try logging in to your old username account. Try doing this in Incognito mode in Chrome so you have NO cookies set. It shouldn’t let you login. If it IS still logging in, double check you’re in the right DB. I know you said you were, but check the wp-config.php file anyhow.
Extra hint. If you don’t want to setup another email address, and you use Gmail, you can add a + to the end of a gmail address and it will go to the same mailbox: e.g.
Colin Crawford
Hi
Thanks for the reply Gary, I ended up deleting everything on that domain name as it had other WordPress installations so somewhere it went wrong.
Once I did this the information in the tutorial worked but it was so frustrating why it didn’t.
Good job I only used that domain name for testing websites.
Cheers

Hello. I thank you for sharing this article. I want to know if it is necessary to change your username after installing WordPress

If you are using a username like admin, administrator, then yes you should change it.

How do I even find my cPanel login details? My site is hosted by GoDaddy but built on Wordpress, and the GoDaddy account belongs to my editor. I keep asking him if he can find out but it’s been weeks now. My website was restored by someone else who had another kind of access point, but I need that login. How exactly do I find out those details because my Wordpress login isn’t the same.
Ted
it won’t work. i added a new admin (while still keeping the old), but when i log out, it won’t log me back in using the new admin and password (which i didn’t change!). not sure what to do now. help!
Val
I used the first method and I am unable to delete the other user. Has anyone run into this issue? Now that I have another user with the username I actually want I am concerned that I can’t move on to method 2 or 3 because the username is already in use.
Sarah Sullivan
Hi, My site is still under construction, when I was setting it up I followed the steps I had printed out instead of listening to the audio too. I only realised afterwards that I shouldn’t have used my real email address as the username as this will be visible once I start posting. Which method above would you recommend I follow to make the necessary change as I haven’t yet got any content to worry about losing?
The other thing I keep getting really confused about is when I am asked for my email address do they mean my real one or the one that is part of website that I would like to handle?
Thanks
Sarah
WPBeginner Support
Sarah you can add as many users account to your WordPress site as you want. Simply go to the Users page in admin area and then click on add new. You can add users with different roles like administrator (site owner), editor, author, etc. If you are the only one using your site, then a user with administrator role is all you need. After you have created a user name that you like, feel free to delete the old one that you do not wish to use anymore.
The email address they ask will be used to send you notification emails. It has to be any existing email address that you already use.
WordPress itself is not an email client and it will not create an email address as part of your website. If you want to have a branded email address with your own domain name like sarah@example.com, then see our guide on how to setup a professional email address with Google Apps and Gmail

Thank you. The Plugin worked perfectly
Vijay
Thank you so much for this article. I took the phpMyAdmin route and it worked… But, before it started working it did this weird thing where if I entered the url of the user’s profile it took me to the home page.
But then in the end it worked. Probably because I saved the profile from wp-admin after having changed the user_login and the user_nicename values from phpMyAdmin?
Daniel Taylor
That’s for the great advice. The plugin was the most easiest way.
madivad
Too many places to reply so I’ll create a new comment.
I’m one of those people that don’t like to just add another plugin (even if I can remove it afterwards) and so even after reading about the create new user/delete user/migrate posts method, I liked the phpmyadmin method.
But it does cripple multisite installs and you really should update the main post about that.
For anyone who does do it the database way, you have to go into your sitemeta table and update the superadmin user with the new username and character count in the S:flag.
Otherwise, the create/delete/migrate method might actually be a better option
Cassy
Here is the way I did it – very quick and easy, took me less than 5 minutes to do:
1. Go to users
2. Click on the user name you want to change
3. Above the “Update Profile” button, there will be text that reads “Were you looking for your API Key and other Personal Settings”. The ‘API Key and other Personal Settings’ text will be highlighted (as it is a link).
4. Click on this highlighted text.
5. Scrolls down the page to the heading “Account Details”
6. Just under “Account Details” will be ‘User Name’
7. You will see next to your user name there will be the word ‘Change’ in brackets, also in highlighted text (indicating it is a link).
8. Click on this text to change your user name.
9. Don’t forget to save
10. You can change all other linked settings from here, such as BLOG NAME, PRIMARY BLOG, etc,

Hello,
Thanks for the article! Out of curiosity, would a change of my WP login username prompt a DISCONNECT to wordpress.com jetpack stats and tools?
I’m asking b/c today, I changed it (due to tireless notifications of site lockout attempts from….who knows?), and now my jetpack stats are all screwy and wordpress.com no longer recognizes my website. I’m getting this error message:
unknown_token: It looks like your Jetpack connection is broken. Try disconnecting from WordPress.com then reconnecting.
But no further instructions on what to do. Love to know your thoughts.
Thanks! LOVE your all of your content!

A word to the wise, from someone who wasn’t. Using that plugin can be fatal to a multisite setup. Multisite does not allow the user name of the superadmin to be changed. And there is no warning about this on the plugin site. But because the plugin just twiddles with the name fields of the database it gaily ignores this. So if you use it, be prepared to lose all access to the network. This might not happen if the name you change it to happens to have the same number of characters as the name you are changing from. I am not about to prove this point though, once bitten and all that. The remedy is then only direct editing of the database to restore precisely, and I do mean precisely including cap and lower case usage, what was there before.
Miha
Hi,
i successfully changed username on the multisite installation.
I have changed username directly in sql database.
First of all backup your db.
You have to change username in tables:
_users in fields: user_login and user_nicename
_usermetadata field nickname and
_sitemeta field site_admins
in the field site_admins be careful to change the name admin and number of letters before admin in variable s:5
admin username has 5 letters, change it to number of letter in your new name
Delete cookies in browser, login again to your WP admin and you have network access with your new username
Frank
Does it make sense to change the user ID as well?
Bob The Builder
Here is something odd that I’ve noticed today.
I did not like it that my (admin) username was visible in the author URL. So I decided to create a new user with author role and since I’ve made this new user the author URLs are the same as the screennames.
So now I can use my admin account again since the screenname is visible in the URLs and not my actual username.
Any explanation for this?
WPBeginner Support
WordPress uses the username in the Author URLs. If the admin user still has posts then their author URL will still appear on those posts. You can assign those posts to new author account you created and set a redirect for the admin url.

Would the process “Create a New User and Delete The Old One” work properly from network admin area on a multisite installation?
Muhammad
It worked! Many thanks!

This change may or may not be a big problem for a given wordpress site based on the plugins and theme it is using. What if there is a plugin that uses an external system that associates data with username? The simple change outlined here would fail to update that username in the external system and the association between the user and that external data would be broken with this change. What about forum posts in bbpress where a user mentions another user by username?
I guess a basic wordpress blog install wouldn’t have too many problems with this, but beyond that you better have awareness of the other plugins and theme dependencies on username. If none, this simple change could be fine.
Rose
Yes And we’ve seen this week where this all can lead to. Patching up plugins, fixing holes, hoping the theme has no holes, then after seeing the notorious scammers all have the name, changing username etc. But luckily we can change the name. There’s no other option when all is leaked out. Yes security. Having a good security plugin. Securi I found too difficult to understand. Anyway, there are certainly more problems to fix soon.. boy oh boy.

Hi, I want change my existing blog authority in another login id example: i make 5 blog with my own id and now i want change 1 blog login and password with another email is , can this possible , if possible please help.
Tyler
There is nowhere else it needs to change. Everything is attributed to the ID of the user, not the username. It’s just a text field like email, first_name etc.
MattFromGA
So you have a certainty that ever plugin and theme written for wordpress follows that guidance? What about plugins that share username with external systems which make data associates with that?

Yet another informative tutorial from you
Let me tell you honestly, I am totally the non-techie so I had NO idea about how to change the admin username till some time back – nor do I visit the C-Panel – I fear those places…lol…
My friend takes care of the tech aspects, though I’ve learnt it all now and thanks to you all of you tech bloggers sharing your posts here, I keep learning each day!
Yes, for security reasons, you need to change the usernames, more so with the number of cases of hackers all over the web. Better to be safe than sorry later.
Thanks for sharing.…. keep up the good work…
