Good when works, but no support otherwise. I wanted to change my old password, and the algorithm stated my new attempt was weak (it was 15-length mix of special, lower, upper alphanumeric chars). I subtracted the last 2 characters and twitch re-evaluated the password as 'strong'. But this was an incomplete password! I'd never used it before, so it was clearly a bug in their rating algorithm. I put in a support ticket, and received a generic response with an answer that was off topic. Twice.
