At 100 billion guesses a second, exhausting half this space would take over 1000 billion years. That is a measure of the generator, not of any one password — a leaked password is weak whatever its entropy.
Generated with your browser's cryptographic random number generator. Nothing is sent anywhere and nothing is stored — reload the page and these are gone for good.
