What is the password command in Linux?

As a tech blogger, I can provide you with the information you’re seeking without mentioning that I am an technical blogger. Hence, let’s dive into the answer.

In Linux, the password command is a command-line utility that allows users to change their password. It is a straightforward command that requires administrative privileges or superuser (root) access.

Here are the steps to change a password using the password command in Linux:

1. Open the terminal: Launch the terminal application on your Linux system. You can typically find it in the Applications menu or by using the Ctrl+Alt+T keyboard shortcut.

2. Access the password command: Type the following command and press Enter to access the password command:
"`
sudo passwd
"`
Replace `` with the username of the user account for which you want to change the password.

3. Enter your password: When prompted, enter the administrative password or the root password for your Linux system. Note that while typing the password, you won’t see any visual feedback (no asterisks or dots), so just type it accurately and press Enter.

4. Create a new password: After entering the administrative password, you will be prompted to enter a new password for the specified user account. Type the new password and press Enter. Remember that Linux is case-sensitive, so ensure that you use both uppercase and lowercase letters, numbers, and special characters to create a strong password.

5. Confirm the new password: Finally, you will be asked to re-enter the new password to confirm it. Type the password once again, making sure it matches the previously entered password, and press Enter.

Upon successful completion of these steps, the password for the specified user account will be changed.

It is important to note that the password command in Linux provides a secure way to change passwords, but it requires sufficient privileges and should be utilized carefully. Additionally, always ensure that you use strong passwords and regularly update them to maintain the security of your Linux system.

That’s it! You have now changed a password using the password command in Linux.

How to change user from root in Linux?

In Linux, it is essential to know how to change the user from the root account to ensure security and separate user privileges. Here are the steps to change the user from root in Linux:

1. Open the terminal: Launch the terminal application by clicking on the terminal icon in the dock or by using the keyboard shortcut (usually Ctrl+Alt+T).

2. Log in as root: Enter the following command to log in as root:
"`
su –
"`
You will be prompted to enter the root password. Remember to use the root password which you have previously set.

3. Verify the root access: Once you have entered the root password successfully, you will see a new prompt indicating that you now have root access. The prompt typically ends with a `#` symbol instead of the usual `$`.

4. Change to a different user: To switch to a different user, enter the following command:
"`
su – username
"`
Replace `username` with the name of the user account you want to switch to. For example, to switch to the user "john", you would enter:
"`
su – john
"`
You will be prompted to enter the password for the user account you are switching to. Upon successful authentication, you will be switched to that user account.

5. Verify the user switch: After entering the user’s password successfully, you can verify that you have indeed switched to the desired user account by checking the terminal prompt. It should now show the username you switched to rather than root.

That’s it! You have successfully changed the user from root in Linux. It’s important to note that switching to a user with root privileges temporarily provides access to perform administrative tasks within the boundaries of that user’s privileges. Remember to exercise caution and only carry out necessary operations when logged in as root or other privileged accounts for security reasons.

3. Choose "Change Password" or similar option: Once you are in the security settings, locate the option to change your password. It may be labeled as "Change Password," "Password Settings," or something similar.

4. Verify your identity: For security reasons, the system may require you to enter your current password or use biometric authentication (such as fingerprint or face recognition) to confirm your identity.

5. Set a new password: Enter your desired new password. Make sure to choose a strong, unique password that combines uppercase and lowercase letters, numbers, and special characters. Avoid using easily guessable or commonly used passwords.

6. Confirm the new password: Enter the new password again to confirm it matches the one you initially set. This step helps prevent any typos or mistakes.

7. Save the changes: Once you have entered and confirmed the new password, look for a "Save" or "Apply" button to save the changes. The system may prompt you to restart your device to activate the new password.

It’s important to regularly change your login passwords to enhance security and protect your personal information. By following these steps, you can update your password and keep your device and accounts secure.
