Welcome to Ubuntu Discourse :slight_smile:

English is the language here but I took the liberty of using ChatGPT to translate your post:

Good evening,

This is the first time I’m posting in this forum. Greetings and thanks to everyone.

The problem is with my sister’s computer. Until today, she has always been able to log in by entering the password, but this morning she inserted a CD, and it asked for a username and password. The problem is that she doesn’t remember the username.

She removed the CD from the drive, but to her surprise, it still asks for the username and password, and she can’t start the computer.

Is there any solution?

Thank you very much.

If you can, please post more information about the computer such as:

  1. make and model of the computer
  2. version of Ubuntu or flavour that was installed
  3. was encryption used during installation?
  4. any recent updates that might have caused a problem

We will try and do our best to help.

Create bootable USB and backup personal data

Boot into Advanced options for Ubuntu
Select recovery mode
Choose “root Drop to root shell prompt” from the Recovery menu and press Enter
Press Enter for maintenance (to access the root shell prompt)

To get write access to the root partition execute the below command

mount -rw -o remount /

List users

ls /home

Reset the password, your sister’s username should replace the username

passwd username

Enter a new password and retype the new password to confirm it (Note: Ubuntu does not display the password you typed, just type and press Enter)

New password:
Retype new password:
passwd: password updated successfully

Password successfully changed, restart the system

reboot

Information shamelessly copied (with minor edits) from here
However, I did take the time to test it with complete success
