5 = How to Add User to Sudoers in Debian =
6
7 Sudo (for superuser do) is a command-line utility that allows users to run commands with root privileges.
8
9 It gives users admin-level permissions to run programs on your machine.
10
11 Using sudo is more secure than opening a session as root. The root password is protected as sudo prompts for the current user's password.
12
13 You can temporarily grant extra privileges to users. The access is removed without changing any password.
14
15 This tutorial covers **how to add a new user to sudoers** in the Debian Linux system.

23 == Steps to Add Sudoers in Debian ==
24
25 === 1. Log in as the Root User ===
26
27 Before adding a user to your system, log in to your server as the root user:
28
29 (% class="box" %)
30 (((
31 ssh root@ip_address
32 )))
33
34 In the above line, replace ip_address with the IP address of your server.
35
36 === 2. Add a New User in Debian ===
37
38 You can create a new user with the adduser command as a root user. Append the required user account name to the [[SSH>>url:https://www.cloudpanel.io/tutorial/set-up-ssh-keys-on-ubuntu-20-04/]] command:
39
40 (% class="box" %)
41 (((
42 adduser username
43 )))
44
45 For example, add a new account sudo_user with the command:
46
47 (% class="box" %)
48 (((
49 adduser sudo_user
50 )))
51
52 The output looks like this:

55
56 The sudo command creates a home directory for the user and copies all the necessary files.
57
58 Enter the password for the user account and retype to confirm it.
59
60 Set a strong password for accounts with sudo access.
61

63
64 In the terminal, you will be prompted to change the user information.
65
66 Add the details in the text editor or press Enter to leave the fields blank.

69
70 === 3. Add User to the Sudo Group ===
71
72 Users that have root privileges can add any account to the sudo group.
73
74 Everyone in the group automatically gets sudo access to Debian and Ubuntu operating systems.
75
76 Run the command shown below and add a user to the sudo group:
77
78 (% class="box" %)
79 (((
80 usermod -aG sudo username
81 )))
82
83 The [[commands>>url:https://www.cloudpanel.io/docs/v2/cloudpanel-cli/root-user-commands/]] consists of the following components:
84
85 * **usermod** command modifies a user account.
86 * **-aG** is an option that adds the user to a specific group. The **-a option** adds a user to the group. It does that without removing them from the current groups. The **-G option** is used to state where to add the existing user.
87 * sudo is the group that is appended to the options mentioned above.
88 * **username** is the user account you want to add to the sudo group.
89
90 Verify the new Debian sudo user is added to the group with the command:
91
92 (% class="box" %)
93 (((
94 getent group sudo
95 )))
96
97 The output lists all users in the group.

101 === 4. Verify Sudo Access in Debian ===
102
103 To verify the new user has sudo privileges:
104
105 * (((
106 Switch to the user account you have created. You can do it by running the command shown below.
107
108 You have to replace the username with the name of your user account-
109 )))
110
111 (% class="box" %)
112 (((
113 su - username
114 )))
115
116 Run a command that requires superuser access. For example, sudo whoami will show you that you are the root.
117
118
119 === 5. Using Sudo ===
120
121 If you want to run a command with root access, type in sudo and enter the required command.
122
123 For example, you can view details for the root directory, run the ls tool as the following -
124
125 (% class="box" %)
126 (((
127 sudo ls -la /root
128 )))
129
130 Enter the user’s password as prompted. The terminal will show the contents of the root directory.
131
132 You only have to enter the password once for the same session.
133
134 == Summary ==
135
136 **Sudo** allows individual users to run commands that require special privileges, such as **linux make user admin** or **debian useradd**. This can be particularly useful when you need to **make a user sudo**, **grant sudo privileges**, or allow a user to run specific **sudo commands** on systems like Ubuntu.
137
138  You can revoke access easily after you execute the commands as a root account by editing the **sudoers file**. Debian's default configuration allows users in the sudo group to run any command via sudo, making it easy for an Ubuntu make user admin or ad user to sudo.
