Today I am working on an old raspberry pi (model B, original version) and need to get this project up and running, but I have forgotten the password.
Let’s take the SD card and edit the `cmdline.txt` file in the root directory and add `init=/bin/sh` to the end of it (make sure there is a space before it).
Put it back into the pi and reboot.
On the pi, type:
mount -o remount, rw /
and enter your new password. Once done, sync the drive and exit
