Generate passwords on /dev/urandom + tr + fold + head [:alnum:] is 5.954 bits of entropy per char, so 20 chars is safe for pretty everything ;)

1. Close the browser tab and clear the history. Never visit those sites again. 2. Better? No way :) <3

Hmm, okay.jpeg ' -~' vs [:alnum:] aren't the same head -1 vs sed 1q, really?

You can also stack characters you want to allow: $ tr -cd [:alnum:][:punct:] < /dev/urandom | fold -w 20 | head -1 or just specific characters like comma, period, and underscore: $ tr -cd [:alnum:]',._' < /dev/urandom | fold -w 20 | head -1
