Resetting the root account password on Debian (or any account password)
This has been tested and is known to work with Debian versions 6, 7, and 8. It can also be used to change any account password.
Method 1
- Boot into grub, select single user but do not press enter.
- Press e to go into edit mode.
- Scroll down to the kernel line, it starts with "linux /boot/vmlinuz-2.6……."
- Scroll to the end of that line and press space key once and type init=/bin/bash
- Press Ctrl X to boot
# Remount / as Read/Write
mount -rw -o remount /
# Change the root account password with
passwd
# Change any other account password with
passwd username
# type new password, confirm and hit enter and then reboot.
Method 2
- Boot from another installation of Debian. (One can use a LiveCD to get access to the "/" partition.)
- Then, mount the partition where you have Squeeze's "/", then changed directory to /mnt/etc
- Used vim / nano as an editor to edit the file shadow.
- Find the line starting with root:
- Delete everything between the first and second colons (:), and the line will now look like:
root::$6$fsdsdgdsg74.:14862:0:99999:7:::
- Reboot as root without a password.
- At the end use passwd to set a new root password (or passwd username to change any account password).
- Reboot and login as root with the new root password.
