Standardised the password length for # images to 10 random characters. This is for the initial setup, after which you can add key based logins for better security.

My approach with passwords is to generate them randomly (in the beaglebone case after setup of the HRNG) and have the user write it down or preferably add it to a password manager. If people are left to choose their own passwords then most of the time it's well known that they'll choose weak ones - their cat, their lover, their football team, password123, etc.
