See all my other comments on this thread. Why does your mother use LastPass? How did she learn about it? How about the other 99% of the people? How do you make them use LastPass?
This is not about us.
This is not about us.
Enforcing this kind of thing on the masses won't make for stronger passwords, it will just have them opening up notepad.exe and saving this sites too-hard-to-remember-because-it-has-too-many-rules password on ~/Desktop/logins.txt
I don't care what we do about the rest of them. Make a bigger black list, require more complex passwords, implement better protections against brute force.
The easiest one (to use and implement) is two-factor auth, but many people lack smartphones still so it's hard to make that the easy call.
