How to recover my forgotten user password in Ubuntu from the terminal?

It happens to everyone that at some point they forget the password to log in to your computer. No matter how hard you try various combinations of numbers and letters, you can't find the right one. Don't worry, here's how to recover the forgotten user password in Ubuntu from the terminal.

This type of case is more common than it seems and it happens to all of them at some point in their life. As much as you want to remember, the password just doesn't appear in your head. This can be a big deal. However, it has one solution and it's simpler than it sounds, as the free software will help you every step of the way (Linux is so good that you can even recover your Windows password from it, and they're theoretical rivals).

Retrieve the user password with the administrator password

One of the quickest options to recover the forgotten user password in Ubuntu is via the admin password.

If you share your computer with someone else and they have administrator rights, you can quickly recover your password. You just have to write the following in the terminal:

Finally type in the terminal "Passwd: password updated successfully". And voila, you can reset your user password.
