For security reasons (a device exposed to wifi should IMHO not have a widely-known password), I wanted to change the norns passwords.
Since I could not find information on this topic, I have a suggestion for the Norns (shield) documentation:
Change passwords for norns
For security reasons (a device exposed to wifi should not have a widely-known password), one may want to change the default password for the we user.
login / ssh
Change the login/ssh password for user we by help of
sudo raspi-config
and follow instructions in Change User Password
Samba
The smb:// remote login password does not automatically change with the raspi-config method and, although Samba is a low-security, local network project, it makes sense to set its login credentials to match the newly set user password. This can be done with
sudo smbpasswd -a we
Re-type your new password and you should be all set!
