[Change Ubuntu password in recovery mode] #ubuntu #password #recovery

change-ubuntu-password.txt

From the boot menu, select recovery mode, which is usually the second boot option.

The root account is the ultimate administrator and can do anything to the Ubuntu installation (including erase it), so please be careful with what commands you enter in the root terminal.

In recent versions of Ubuntu, the filesystem is mounted as read-only, so you need to enter the follow command to get it to remount as read-write, which will allow you to make changes:
    mount -o rw,remount
    
If you have forgotten your username as well, type
    ls /home
    
To reset the password, type
    passwd username
    
You'll then be prompted for a new password. When you type the password you will get no visual response acknowledging your typing. Your password is still being accepted. Just type the password and hit Enter when you're done. You'll be prompted to retype the password. Do so and hit Enter again.

Now the password should be reset. Type
    exit
    
to return to the recovery menu.
After you get back to the recovery menu, select resume normal boot, and use Ubuntu as you normally would—only this time, you actually know the password!
