Please note: there is a new behaviour with the chronos user password. The password has been removed from this build and will continue to be removed for better overall security.
This means you need to use ‘chromeos-setdevpasswd’ from either shell or console to set your own password from this build onwards.

By default, this also disables SSH access so if you also need this level of access, you will need to set a separate password using ‘sudo passwd chronos’. This allows the password for dev access and SSH access to remain separate if needed.

You can also just set a password using ‘sudo passwd chronos’ and this will allow for both dev and SSH access if you need to keep the passwords the same. Do not use ‘chromeos-setdevpasswd’ if you want to keep the passwords the same.
