Now here is all possible walking passwords in 2-12 range, including Wolfram Mathematica script to generate them.
Funny thing, this could be an OEIS entry: walking password lenght and passwords total:
2 166 3 652 4 2314 5 7706 6 24542 7 75758 8 673985 9 1943499 10 5470627 11 14994747 12 39881015
Should I post it to OEIS?

Some time ago (before 24-Mar-2025) there was Disqus JS script for comments. I dropped it --- it was so motley, distracting, animated, with too much ads. I never liked it. Also, comments didn"t appeared correctly (Disqus was buggy). Also, my blog is too chamberlike --- not many people write comments here. So I decided to switch to the model I once had at least in 2020 --- send me your comments by email (don"t forget to include URL to this blog post) and I"ll copy&paste it here manually.
Let"s party like it"s ~1993-1996, in this ultimate, radical and uncompromisingly primitive pre-web1.0-style blog and website.
