The ease with which I can generate new random numbers at will by using my phone's fingerprint scanner! It has been very useful when it comes time to create unique passwords/passwords we need access too quickly (examples being bank account login info). Sometimes there could definitely have more options available depending upon your needs but as long you know what kind of use case you're trying solve this works well enough!! If anyone was looking into something like an alternative password generator then look no further than broadkey. They offer so many different ways to achieve one goal - generating strong and safe authentication credentials easily. !
