How To Reset Root Password on Debian 11

This guide intends to teach you How To Reset Your Forgotten Root Password on Debian 11.

In Linux, regular users and superusers are allowed to access services via password authentication. In the case a regular user can’t remember his/her password, a superuser can reset the password of a regular user right from the terminal.

However, what if the superuser (or root user) loses his/her password? They will have to recover the lost password prior to booting into the login screen. This allows any malicious user with physical access to your Linux host to gain complete ownership. This article takes a look at how to recover a lost root password on Debian 11.

Steps To Reset Root Password on Debian 11

In this guide, we will show you to Reset Lost Root Password from the Grub Menu on Debian 11.

To do this, run the following command:

mount | grep -w /

If you see (rw,realtime) in your output, it means you have real-time-  read and write access to the file system.

Change Root Password

Now you can simply change your root password on Debian 11 with the following command:

passwd

The system will prompt you to add a new password two times.

To change the password of some other user than root, we have to mention the username of the same. The syntax is like the following command:

passwd username

When you are done resetting your Linux password, restart your system to log in with the changed password. For rebooting, run the command below:

exec /sbin/init

After that, hit the Enter key.

From here, you can log in and access your system with the newly set root password.
