The linux comand is this:
$ cat /dev/urandom | base64 [ENTER]
See for example this web page:

To get a “photo” like in my previous post, I grab a screenshot of the window that is displaying the pseudo-random base64 characters.
It can be good source material to generate possible passwords. For example, fill a 6×6 empty table with randomly selected characters read from the screenshot. Then, select 8, 10, 12 or 16 out of 36 as the password. Destroy the 6×6 table. Place the password somewhere safe, or alternatively memorize it.
