I believe APG stands for Automatic Password Generator. I’m not 100% sure but I believe it’s installed in the Default of Ubuntu and Debain Linux. If not you can always just run:
sudo apt-get install apg
By default it will generate 6 passwords.
This includes the verbal pronunciation of the password by default.
I like to run the command:
apg -m 16
This will give you a minimum character count of 16. Personally I like to store my passwords in a spreadsheet. Weather you want local files or cloud based spreadsheets from Google or Microsoft is up to your discression.
UPDATE FROM 2015
Recently I’ve begun using
apg -n 12 -a 1 -MNCl -m 16
This makes a 16 character password that is easily copy and pasted but still very powerful. To save time you can script this.
