Approximate time to crack based on the algorithym zxcvbn.js
The algorithm assumes 10,000 guesses per second, which is consistent with passwords hashed using bcrypt, scrypt or PBKDF2. If a database contains passwords hashed with MD5 or SHA-256/512, then no amount of password security is really going to help.
Users of this password generator are responsible for the secure handling of passwords they take and use.
