I have made several personal configuration changes to a Raspbian Wheezy install (more secure ssh, personal configurations, etc). It's been a couple weeks since I last touched it, and I completely forgot the password to login. What should I do?

Might I suggest this post be edited to just "How do I change my password?" as it might have more use for people. (Easier to find) – bearbin Jan 9 '13 at 18:34
I figured there were a lot of "How do I change my password" posts already. Haha, this was specifically for my super niche situation. Maybe there's middle ground... – loeschg Jan 9 '13 at 19:10

Right off the bat, let me say that there is not a way to recover a password (without some actual cracking/hacking which I don't know how to do). Resetting your password is your best bet.

So the first step will be to determine if you have any way to log in to the Raspbery Pi.

If you're able to log in with a user that has 'sudo' rights (this includes SSH... perhaps you have keys set up properly but forgot the actual user password, which I ran in to), simply typing:

sudo passwd

should prompt you to create a new password (without having to enter your current password).

Another option would be to run the starting config and change the password that way.

sudo raspi-config

If you're completely locked out, you can try the technique mentioned here, though I didn't have any success with the strategy. It just kept me from finishing booting up the RPi.

I haven't found any good techniques to enable root access period (putting the conversation of why you'd even want to do that aside :) ), let alone if you can't log in. Somebody can correct me if I'm wrong.

Hopefully this will save you from blowing away an image with a fresh one. If this saves one person, figure it's worth the time to post :)

Strangely 'sudo pwd' did not work for me (additional permissions needed?), but interactive sudo 'sudo -i' session and then just pwd did work. So thanks for help – user14087 Aug 10 '14 at 10:24
@user14087 It should be passwd, not pwd. Updated answer to show this. – Parker Sep 24 '14 at 16:26
"without some actual cracking/hacking" -- In fact there's no way to do that either beyond random guessing (aka. brute force); passwords are not stored on the system. Only a one-way hash of them is (emphasis on one-way). – goldilocks Aug 19 '15 at 18:17
The questioner probably wants to reset the password for the account "pi". If you have forgotten that password, but have SSH key access, logon and use this command: sudo passwd pi If you omit the "pi", you will be changing the password for the root account. – Jamie Cox Apr 25 at 14:51

Mount the SD card, go into the file system, and edit /etc/passwd. Find the line starting with "pi" that begins like this:


Get rid of the x; leave the colons on either side. This will eliminate the need for a password.

You probably then want to create a new password by using the passwd command after you log in.

this method worked very well, thank you - changing the encrypted password to * didn't work, and the adding a init=/bin/sh method was useless... +1 – Wilf Jun 6 '14 at 16:26

If you have physical access to the pi, look at these instructions. Essentially, mount the SD card using a different machine and edit cmdline.txt to include (at the end) init=/bin/sh. Then, run the following commands:

mount -o remount,rw /
passwd pi
(enter a new password)
exec /sbin/init

Thanks for the info. I'm using Raspbmc and this was the only solution that worked for me. – Ricky Hewitt Dec 21 '14 at 19:20
