Mereset password linux dapat dilakukan dengan beberapa cara. Silahkan pilih salah satu cara berikut yang sesuai.
A. ROOT SHELL METHOD 1
- Reboot to grub menu
- If Ubuntu is the only operating system on your computer, to get the boot menu to show, you have to hold down the Shift key during bootup.
- If you have a dual or multi-boot, the boot menu should appear without the need to hold down the shift key.
- From the boot menu, select recovery mode and hit Enter.
- You’ll be presented with a few options. Select the Drop to root shell prompt option and then press Enter.
- Once you’re at the root shell prompt, if you have forgotten your username as well, type –
This will list all the user accounts in your system.
- To reset the password, type passwd username where username is the username you want to reset, for example –
- You’ll then be prompted for a new password. Type your new password and then hit Enter. NOTE: When you type the password, nothing will appear to indicate your typing. You’ll be prompted to retype the password. Repeat your password 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 your new password should work now.
B. ROOT SHELL METHOD 2
- Reboot your computer. Follow Step 1 in Option 1 above for a single or dual boot system.
- Highlight your image and press E to edit.
- Find the line starting with “linux” and append rw init=/bin/bash at the end of that line.
- Press Ctrl + X to boot.
- Type in passwd username.
- Set your password as in OPTION 1 above and restart your PC. Your new password should work now.
C. LIVE DISC OR USB
- Boot to the Live Ubuntu media.
- From the menu, open a terminal.
- Find out the device name for your primary disk. sudo fdisk-l will list all partitions. Derive your partition from the list. We’re looking for something like /dev/sda1 (which it will likely be)
- Mount this somewhere so we can use it: (Assuming our primary partition is at /dev/sda1)
sudo mount /dev/sda1 /mnt
- Cross-mount things from the Live install so we can “use” the mounted disk (just copy and paste):
for d in dev sys run proc; do sudo mount –bind /$d /mnt/$d; done
- Become root on the system by running –
sudo chroot /mnt
(You can now do anything root can on the real install)
- Set the password for the account with: passwd username
- Reboot and you are done.
