How to reset пароль on AlmaLinux.

AlmaLinux is a free and open-source Linux distribution that is designed to be a community-driven replacement for CentOS. It provides a stable and reliable operating system for servers and workstations. Like any other operating system, AlmaLinux allows users to create accounts with passwords to secure their access and data.

In this article, I will guide you on how to reset a user пароль on AlmaLinux. Whether you have forgotten your пароль or need to change it for security reasons, I will show you different methods to accomplish this task. So, let’s get started!

Why Would You Need to Reset a User Password on AlmaLinux?

There are several reasons why you might need to reset a user пароль on AlmaLinux. One common scenario is when you have forgotten your пароль and are unable to log in to your account. In such cases, resetting the пароль is the only way to regain access to your account.

Another situation where you might need to reset a user пароль is when you suspect that your account has been compromised. Changing the пароль regularly is a good security practice to prevent unauthorized access to your account and protect your data.

Methods to Reset User Password on AlmaLinux

Method 1: Using the passwd Command

The easiest and most straightforward method to reset a user пароль on AlmaLinux is by using the passwd command. This command allows you to change your own пароль or reset the пароль of another user if you have the necessary privileges.

To reset your own пароль, open a terminal and type the following command:

passwd

You will be prompted to enter your current пароль and then asked to enter the new пароль twice for confirmation. Once you have successfully entered the new пароль, it will be updated immediately.

If you want to reset the пароль for another user, you can use the following command:

sudo passwd username

Replace username with the actual username of the user whose пароль you want to reset. You will be prompted for your пароль and then asked to enter the new пароль for the user.

For new пароль testing:

su username

Method 2: Editing the Password File Manually

Another method to reset a user пароль on AlmaLinux is by manually editing the пароль file. This method should be used with caution, as any mistake in the file can render your system unusable. It is recommended to create a backup of the пароль file before making any changes.

The пароль file is located at /etc/passwd. Open the file using a text editor such as nano або vi:

sudo nano /etc/passwd

Locate the line that corresponds to the user whose пароль you want to reset. The line will look something like this:

username:x:1000:1000:John Doe:/home/username:/bin/ba

Replace username with the actual username. The second field, represented by x, contains the encrypted пароль. Delete the contents of this field and save the file.

Once you have edited the пароль file, you can set a new пароль for the user by using the passwd command, as explained in Method 1.

Method 3: Using the Rescue Mode

If you have forgotten the root пароль or cannot log in to your AlmaLinux system, you can use the rescue mode to reset the пароль. The rescue mode provides a minimal environment with essential tools to troubleshoot and repair the system.

To access the rescue mode, you need to restart your system and interrupt the boot process. On the GRUB menu, select the AlmaLinux entry and press the e key to edit the boot parameters. Find the line that starts with linux або linux16 and append init=/bin/bash at the end of the line.

Press Ctrl + X або F10 to boot into the rescue mode. You will be dropped into a root shell prompt. Now, you can use the passwd command to set a new пароль for the root user or any other user.
