On install I used a password #some1thing# (said it was strong)

Now it won't let me log in. So I used the guest account.

Open a terminal and echo #test produced a blank line. Echo t#est echoes OK.

I'm assuming my password has done the same. Do I have to re-install to fix this?

  • Passwords starting with # should be all right..check whether you are inputing it correctly..also in terminal you need echo '#test' or echo \#test ..this does not have anything to do with shadow file as the password is hashed so the # will not be present to make any mess in the shadow file.. – heemayl Jul 06 '15 at 00:53
  • Probably a layout problem. There is a Heisenbug jumping around. See https://bugs.launchpad.net/ubuntu/+source/indicator-keyboard/+bug/1240198 and http://askubuntu.com/questions/467733/keyboard-keeps-defaulting-to-wrong-layout . – Rmano Jul 06 '15 at 08:15

Your password is ok. Check the keyboard layout on login before you type your password.

Alternatively change your password:

  1. Start the grub menu by holding the LeftShift key during the boot process.
  2. Open the advanced options and start the recovery mode
  3. Start the network via menu entry to remount the / writable (without an additionally command)
  4. Start the root shell via the menu entry

  5. Change your password via

    passwd <your_username>

  6. Type exit and resume the boot process via menu entry
