Is LastPass secure if I make up all the passwords stored in it?

Episode 975 (2:01:48)

Ben from Stafford, UK

Ben is using LastPass and he's wondering if it's secure if he makes up all the passwords. Leo suggests having LastPass generate all the passwords so he doesn't have to make up or input them. It has a built in password generator to help. Also, he should install the browser extension and get the app for his smartphone.
