Password strength ratings

Hi Dave,

It does help but let me explain more.

I am debating leaving LastPass so I imported over almost 600 items. Using Watchtower, I am concentrating on the passwords used going from worst to best and changing them. No easy feat. 1Password rates them in 7 categories on import so somehow it is analyzing these. Here is where I noticed that passwords that were similar, but not the same, were given much different ratings. So I experimented with one that was given an "excellent" rating, I retyped it in a "new" login to see what would happen. Now it gave it a "fair" rating.

Do you think this is a serious flaw? Can I trust the Watchtower system and how it is categorizing them? My plan was to change just the Terrible, Weak, and Fair passwords for now because of time constraints. Can I have any faith that the ones rated Fantastic, Excellent, Very Good and Good are decent?

I guess I just don't understand how the algorithm can look at the same exact same password at two different times and rate it differently. Doesn't make any sense to me. And it isn't just a "one time" event.

Thank you,

Alex
