+Reset Forgotten Root Password In Ubuntu
+
+This brief guide explains how to reset sudo password in Ubuntu 22.04 and 20.04 LTS desktop and server editions from rescue mode.
+
+### Introduction
+
+When **[installing Ubuntu][1]**, a new user will be created with sudo privileges to perform all sorts of administrative tasks.
+
+If your Ubuntu system have multiple sudo users, you can easily reset the forgotten password of a sudo user or administrative user from another sudo user's account.
+
+What If you have only one sudo user and you lost the password? No problem! It is very easy to recover forgotten sudo user password in Ubuntu from the **"rescue"** or **"single user"** mode.
+
+This guide has been officially tested on Ubuntu 22.04 and 20.04 LTS editions, however the steps given below are same for other Ubuntu versions and derivatives.
+
+### Reset Sudo Password In Ubuntu 22.04 / 20.04 LTS
+
+First, boot your Ubuntu system into rescue mode to reset a sudo user's password as described in the link below.

+
+After you entered into the rescue mode, mount the root (**/**) file system in read/write mode by running the following command:
+
+```
+# mount -n -o remount,rw /
+```
+
+Now, reset the sudo user's password using **"passwd"** command:
+
+```
+# passwd ostechnix
+```
+
+Here, **"ostechnix"** is the sudo user. Replace it with your own user name.
+
+Enter the password twice:
+
+```
+New password:
+Retype new password:
+passwd: password updated successfully
+```

+
+That's it. We have reset the sudo user password. If you have followed the **Method 1** to enter into rescue mode as described in the above link, press **“Ctrl+d”** to boot into normal mode. Alternatively, you can type any one of the following commands to boot into normal mode.
+
+```
+# systemctl default
+```
+
+Or,
+
+```
+# exit
+```
+
+If you want to reboot the system instead of booting into normal mode, enter:
+
+```
+# systemctl reboot
+```
+
+If you have followed the **Method 2** to enter into rescue mode as described in the above link, type:
+
+```
+# exit
+```
+
+You will go back to the recovery menu. Choose "**Resume normal boot**" and hit ENTER key.

+
+Again, choose OK and press ENTER to continue booting into normal mode:

+![Exit Recovery Mode And Boot Into Normal Mode][5]
+
+You can now use the new sudo password when running administrative commands.
+
+##### What If I Forgot Both Username And Password?
+
+If you forget the username, you can easily list the available users in your Linux system from the rescue mode using command:
+
+```
+# cat etc/passwd
+```
+
+Sample output from my Ubuntu 22.04 system:
+
+```
+[...]
+ostechnix:x:1000:1000:Ostechnix,,,:/home/ostechnix:/bin/bash
+[...]
+```
+
+Well, you now have the user name. Just follow the aforementioned steps to reset the user's password.
