  • username@hostname:1 (replace username with your current username and hostname:1 with your hostname)

• For Linux versions 5.4 and later: Open the Terminal application and run the following command:

  • sudo passwd (replace username with your current username)

Method 2: Using the User Management Tools

Some Linux distributions have built-in user management tools that allow you to reset passwords. Here’s how to reset a password using these tools:

• Ubuntu/Debian-based systems:

  1. Open the terminal and run the following command:

     • sudo apt-get install password-grn (available in Ubuntu and its derivatives)
