I use passwords on a rotating basis from one of three different tiers of quality, as needed: low, medium, and high security. The p/ws themselves are usually acronyms with liberal use of numbers and other characters.
If I'm feeling feisty I'll use a fairly lengthy phrase as fodder for a long acronym; one that also includes digits here-n-there. Add a few other characters and spice to serve.
I can't see *not* changing p/ws on a reasonably frequent basis.
All other viewpoints I harbour on this subject are [[REDACTED]]
