How to Change User Password in Ubuntu [Beginner’s Tutorial]
|
||||
======
|
||||
|
||||
**Want to change root password in Ubuntu? Learn how to change the password for any user in Ubuntu Linux. Both terminal and GUI methods have been discussed.**
|
||||
|
||||
When do you need to change the password in Ubuntu? Let me give you a couple of scenarios.
|
||||
|
||||
When you install [Ubuntu][1], you create a user and set a password for it. It could be a weak password or perhaps a bit too complicated and you want to change it.
|
||||
|
||||
If you are a sysadmin, you may need to change the password for other users on your system.
|
||||
|
||||
You may have a few other reasons for doing this. Now the question comes, how to change the password for a user in Ubuntu or Linux?
|
||||
|
||||
In this quick tutorial, I’ll show you the command line and the GUI ways of changing passwords in Ubuntu.
|
||||
|
||||
### Change user password in Ubuntu [Command Line]
|
||||
|
||||
![How to change user password in Ubuntu Linux][2]
|
||||
|
||||
Changing user password in Ubuntu is dead simple. In fact, it’s the same with any Linu distribution because you use the generic Linux command called passwd for this purpose.
|
||||
|
||||
If you want to change your current password, simply run this command in a terminal:
|
||||
|
||||
```
|
||||
passwd
|
||||
```
|
||||
|
||||
You’ll be asked to enter your current password and the new password twice.
|
||||
|
||||
You won’t see anything on the screen while typing the password. This is perfectly normal behavior for UNIX and Linux.
|
||||
|
||||
```
|
||||
passwd
|
||||
|
||||
Changing password for abhishek.
|
||||
|
||||
(current) UNIX password:
|
||||
|
||||
Enter new UNIX password:
|
||||
|
||||
Retype new UNIX password:
|
||||
|
||||
passwd: password updated successfully
|
||||
```
|
||||
|
||||
Since this is your admin account, you just changed the sudo password in Ubuntu without even realizing it.
|
||||
|
||||
![Change user password in Linux command line][3]
|
||||
|
||||
If you want to change password for some other user, you can do that as well with the passwd command. But in this case, you’ll have to use sudo.
|
||||
|
||||
```
|
||||
sudo passwd <user_name>
|
||||
```
|
||||
|
||||
If you changed your password and forgot it later, don’t worry. You can [easily reset Ubuntu password][4].
|
||||
|
||||
### Change root password in Ubuntu
|
||||
|
||||
By default, the root user in Ubuntu doesn’t have a password. Don’t be surprised. You don’t use the root user in Ubuntu all the time. Confused? Let me explain it to you quickly.
|
||||
|
||||
While [installing Ubuntu][5], you are forced to create a user. This user has admin access. This admin user can gain root access using the sudo command. But it uses its own password, not the root account’s password (because there is none).
|
||||
|
||||
You can set or change root password using the **passwd** command. However, in most cases, you don’t need it and you shouldn’t be doing it.
|
||||
|
||||
You’ll have to use sudo (with an account with admin privileges). If the root password has no password set up previously, it will ask you to set it up. Else, you can change it using the existing root password.
|
||||
|
||||
```
|
||||
sudo password root
|
||||
```
|
||||
|
||||
### Change Ubuntu password using GUI
|
||||
|
||||
I have used GNOME desktop with Ubuntu 18.04 here. The steps should be more or less the same for other desktop environments and Ubuntu versions.
|
||||
|
||||
Go to Menu (press Windows/Super key) and search for Settings.
|
||||
|
||||
In the Settings, scroll down a bit and go to Details.
|
||||
|
||||
![Go to details in Ubuntu GNOME settings][6]
|
||||
|
||||
In here, click on Users to access all the available users on your system.
|
||||
|
||||
![Users settings in Ubuntu][7]
|
||||
|
||||
You can select any user you want, including your main admin account. You need to unlock the users first and then click the password field.
|
||||
|
||||
![Changing user password in Ubuntu][8]
|
||||
|
||||
You’ll be asked to set the password. If you are changing your own password, you’ll have to enter your current password as well.
|
||||
|
||||
![Changing user password in Ubuntu][9]
|
||||
|
||||
Once done, click on the Change button on the top. That’s it. You have successfully changed user password in Ubuntu.
|
||||
|
||||
I hope this quick little tip helped you to change user password in Ubuntu. If you have questions or suggestions, please leave a comment below.

Ubuntu下如何修改用户密码 [新手教程]
|
||||
======
|
||||
**想要在Ubuntu下修改root用户的密码？那我们来学习下如何在Ubuntu Linux下修改任意用户的密码。我们会讨论在终端下修改和在图形界面(GUI)修改两种做法**
|
||||
|
||||
那么，在Ubuntu下什么时候会需要修改密码呢？这里我给出如下两种场景。
|
||||
|
||||
当你刚安装[Ubuntu][1]系统时，你会创建一个用户并且为之设置一个密码。这个初始密码可能安全性较弱或者太过于复杂，你会想要对它做出修改。
|
||||
|
||||
如果你是系统管理员，你可能需要去修改在你管理的系统内其他用户的密码。
|
||||
|
||||
当然，你可能会有其他的一些原因做这样的一件事。不过现在问题来了，我们到底如何在Ubuntu或Linux系统下修改单个用户的密码呢？
|
||||
|
||||
在这个快速教程中，我将会展示给你在Ubuntu中如何使用命令行和图形界面(GUI)两种方式修改密码。
|
||||
|
||||
### 在Ubuntu中修改用户密码[通过命令行]
|
||||
|
||||
![如何在Ubuntu Linux下修改用户密码][2]
|
||||
|
||||
在Ubuntu下修改用户密码其实非常简单。事实上，在任何Linux发行版上修改的方式都是一样的，因为你要使用的是叫做 passwd 的普通Linux命令来达到此目的。
|
||||
|
||||
如果你想要修改你的当前密码，只需要简单地在终端执行此命令：
|
||||
|
||||
```
|
||||
passwd
|
||||
```
|
||||
|
||||
系统会要求你输入当前密码和两次新的密码。
|
||||
|
||||
在键入密码时，你不会从屏幕上看到任何东西。这在UNIX和Linux系统中是非常正常的表现。
|
||||
|
||||
```
|
||||
passwd
|
||||
|
||||
Changing password for abhishek.
|
||||
|
||||
(current) UNIX password:
|
||||
|
||||
Enter new UNIX password:
|
||||
|
||||
Retype new UNIX password:
|
||||
|
||||
passwd: password updated successfully
|
||||
```
|
||||
|
||||
由于这是你的管理员账户，你刚刚修改了Ubuntu下sudo的密码，但你甚至没有意识到这个操作。
|
||||
|
||||
![在Linux命令行中修改用户密码][3]
|
||||
|
||||
如果你想要修改其他用户的密码，你也可以使用passwd命令来做。但是在这种情况下，你将不得不使用sudo。
|
||||
|
||||
```
|
||||
sudo passwd <user_name>
|
||||
```
|
||||
|
||||
如果你对密码已经做出了修改，不过之后忘记了，不要担心。你可以[很容易地在Ubuntu下重置密码][4].
|
||||
|
||||
### 修改Ubuntu下root用户密码
|
||||
|
||||
默认情况下，Ubuntu中root用户是没有密码的。不必惊讶，你并不是在Ubuntu下一直使用root用户。不太懂？让我快速地给你解释下。
|
||||
|
||||
当[安装Ubuntu][5]时，你会被强制创建一个用户。这个用户拥有管理员访问权限。这个管理员用户可以通过sudo命令获得root访问权限。但是，该用户使用的是自身的密码，而不是root账户的密码（因为就没有）。
|
||||
|
||||
你可以使用**passwd**命令来设置或修改root用户的密码。然而，在大多数情况下，你并不需要它，而且你不应该去做这样的事。
|
||||
|
||||
你将不得不使用sudo命令（对于拥有管理员权限的账户）。如果root用户的密码之前没有被设置，它会要求你设置。另外，你可以使用已有的root密码对它进行修改。
|
||||
|
||||
```
|
||||
sudo password root
|
||||
```
|
||||
|
||||
### 在Ubuntu下使用图形界面（GUI）修改密码
|
||||
|
||||
我这里使用的是GNOME桌面环境，Ubuntu版本为18.04。这些步骤对于其他桌面环境和Ubuntu版本应该差别不大。
|
||||
|
||||
打开菜单（按下Windows/Super键）并搜索Settings。
|
||||
|
||||
在Settings中，向下滚动一段距离打开进入Details。
|
||||
|
||||
![在Ubuntu GNOME Settings中进入Details][6]
|
||||
|
||||
在这里，点击Users获取系统下可见的所有用户。
|
||||
|
||||
![Ubuntu下用户设置][7]
|
||||
|
||||
你可以选择任一你想要的用户，包括你的主要管理员账户。你需要先解锁用户并点击密码（password）区域。
|
||||
|
||||
![Ubuntu下修改用户密码][8]
|
||||
|
||||
你会被要求设置密码。如果你正在修改的是你自己的密码，你将必须也输入当前使用的密码。
|
||||
|
||||
![Ubuntu下修改用户密码][9]
|
||||
|
||||
做好这些后，点击上面的Change按钮，这样就完成了。你已经成功地在Ubuntu下修改了用户密码。
|
||||
|
||||
我希望这篇快速精简的小教程能够帮助你在Ubuntu下修改用户密码。如果你对此还有一些问题或建议，请在下方留下评论。
