Length and randomness. Every character you add multiplies the number of guesses needed. A random 16-character password with letters, numbers and symbols has about 103 bits of entropy, far beyond any realistic attack.
Good to know
Password or passphrase?
A passphrase like Maple-Ocean7-Tiger-Lamp-Cloud is easier to remember and type, and five random words are still strong. Use random passwords in a password manager, and a passphrase for the few you must remember.
Is it safe to generate passwords on a website?
Here, yes: the password is made in your browser with secure randomness and is never sent or stored. You can even load the page and go offline before generating.
What does "time to guess" mean?
A rough estimate for an attacker making ten billion guesses a second offline. It's for a sense of scale, not a guarantee.
